This is about as simple as you can get to wire lights for your Lifan powered bike. Here is a link for the regulator: 12V 4 Pin Voltage Rectifier Regulator (Half wave) a.co/d/3nHbYPl
This is hands down the best channel for rebuilding/restoring old motorcycles using new motors. I need to check, but knowing how to wire up the brake light (for braking - not just running brake light) would also be very useful.
@@MiniBikeMike I will try this. Thank you so much. I've been restoring a 1962 Honda C110 Super Sports Cub (I put a Lifan 125cc in it) and your videos have been CRUCIAL.
Thank you so much bud. I've never worked on a 2 stroke engine before. I just got a smoking deal on a custom 3 wheel bike. It's pretty fun to ride. Currently the front LED stopped working & the battery won't hold power now. That's a bummer for me. I did started workingbon it following wire by wire slowly 😅 I did kind of sort of figured it out "backwards.😁" But going forward got a bit to confusing 😱🤔 But i found you, & instantly after this well explained video step by step ((forward 😅)) You became our HERO my 3 wheeler & mine. I liked & subscribed to you're channel. Looking forward to educate myself more on this amazing small engines but yet they do have some power to them. Blessings buddy
This here has definitely been a straight narrow most direct video to better understand what it takes to wire from ground zero and yes as far as blinker seems easy enough if we have (+)(-) multi meter ends to find (R)(L) id assume.thanks again awesome vid
😂 too simple just plug and play. How about converting the 30v AC to 12v DC.No readings were givin. Only said green to engine did not say engine as ground.
Thank you for the helpful video it is easy to follow. if you don't mind can you explain how to ad the stock key switch to this setup. I watched the other video and couldn't figure it out. Thank you.
Hi Mike my new lifan 125 does not have a white wire it has red- blue and white- dark green-black-yellow-green and brown. From the wiring harness that came with it the colors are green yellow white and blue with white stripe and black with red stripe any ideas would be much help.
Hi Mike . I'm in the UK I'm struggling to the rear brake foot lever and bracket that sits on the spindle and rear brake cable for a ct70 . Would you have one I could purchase ? Kind regards.
My lifan 125cc has a pink and yellow coming out of the 5 wire stator. Is the pink the same as the “white”? I was able to wire a full wave rectifier but the voltage coming out is high. I would like to get the half wave rectifier work if feasible.
@@effie5125 I had one with a pink wire and never figured out how to get it to work. I wound up buying a new stator on Amazon for $17. It had the white and yellow and worked great.
Hello, Good video! We have an issue with to high voltage, it just blow bulbs and voltage up to 24V. Without the regulator up to 45-50V. I did not wire exactly as you but nearly, i did take everything from the regulator (red wire) didn't split the yellow.. i have tryed with several diffferent regulators but with no luck. another thing is that it seams like it comes AC out of the regulator also.
Mike, thanks for the info. Just got the engine. I see the plug for the kill switch. Is that normally open and when you want to run engine off it closes? Thanks
Hey mike, quick question, i have a skyteam st125 coming, it starts and runs fine on the kickstart but not on the button, has a new battery, everything works when running from kick but nothing from the button, other than checking fuse, ignition switch wiring, is there anything else i could check? Its also running 2 extra guages that work fine also, any tips would be great.
Can you hear the starter solenoid clicking, when you push the button? If you can get to the starter solenoid, check to make sure it’s getting 12v. If it is, jump across the two posts and starter should spin. You can also put 12v directly to the starter. If it doesn’t spin, the starter is bad.
Would there be any difference in running standard bulbs vs led using this method? Would it require some sort of relay? Just ordered this engine and honestly I'm not sure... Any response would be greatly appreciated
I hooked up a battery but it didn't make the headlight brighter my battery is new 12v 7ah led acid battery also will the stator alone power a brighter bulb I have a dirt bike plastic headlight uses a scooter headlight bulb it's to dim it's more of a day running light thanks
The stator can be wired a couple different ways from the manufacture. Most Lifan’s with a yellow wire and a white wire are half wave. The headlight can be powered AC or DC, depending on which wire you hook it too. The yellow wire is AC, the red wire is DC.
My engine doesn’t have a white wire coming out of it, just the 2 yellow wires. so I have nothing to connect the white wire on the voltage rectifier too. Can I get lights to work with out the white wire?
Sounds like a full wave system. Take one of the yellows from engine and tie it together with both the yellow and white wires in the harness. The other yellow from engine goes to ground.
The stator can’t handle the added lights of turn signals, so the first thing you’ll need is to add a battery. If you’re doing all that, it would be much simpler to install a complete 12v harness, for all lights. Trail Buddy has an excellent harness, part number TB422.
@@MiniBikeMike Wow I really appreciate that. I am planning on putting a zs212 into a '76 ct90, planning on running a battery and wanted to do a 12v conversion at the same time. Would that kit still apply for a ct90? I assume so.
@therodenthitman Harness and engine don’t care what frame you put them in. Just be aware, the CT90 uses a different engine mounting spacing. Your engine is NOT a direct bolt in, you’ll need an adapter.
Hey mike i followed your instructions perfectly and ran a switch to my light , only running headlight , my issue is my light worked but it was dimming when i reved & then after turning the light on and off 3 times the light stopped working its an 18w led mini light bar , i ran yellow and red wire from the rectifier to the switch and i attached the red wire from my light to that & the green ground to the switch and then to the light , did i do something wrong ? I also grounded to the frame
Quick question I bought a used kazuma Chinese atv for my girlfriend and the wiring on the starter switch/headlight switch so does the horn but not the head light traced the wires and can’t seem to find where the power is going any help would be greatly appreciated👏
It would be a lot easier to just purchase a full 12v harness from Trail Buddy, that has all the wiring in it. Their part number is TB422. But, if you wanted to run your own wires, tap into the red wire and connect to flasher. From the other terminal on flasher, send wire to turn signal switch. Then, from switch out to signals.
In looking at the wiring coming out of my 110cc engine, instead of a yellow and a white wire for charging it has two yellow wires instead. Is there a way to determine how to hook them to the yellow & white wires in the harness? Thanks.
One of the yellows from engine goes to ground. The other yellow ties into both the yellow and white of harness. Doesn’t matter which yellow of engine goes where.
@@MiniBikeMike Hi Sir, I followed your instructions, using half wave rectifier but i only get 9v in Multimeter which light up a 12v bulb very weak. When I use full wave rectifier, the bulb is light up very strong but the multimeter reads nothing from the rectifier outputs (red and green). Do you know whats wrong with my system ?
I got the lifan 125cc ssr engine installing on Z50 with lights but no battery, Im following your instruction for wiring everything before you start connecting rectifier, completed connection leads from my engine harness wires to the CDI harness leads as follows: blue/white to blue white, red/black to rec/black, green to green. This leaves the white and yellow wires from the engine harness to connect to the rectifier, but I also have one green/red wire with male end in the engine harness, cut it or ignore it? And I also have one more blue/white male end wire in the CDI harness, cut it, ignore it, or splice it in with the blue/white engine wire already connected to the CDI???
The green/red is the neutral indicator wire. If you don’t have a neutral light, you can ignore it. I’ve never seen a harness with a second blue/white wire. I’d leave it unplugged. If you have spark, you can cut it or ignore it. Some harnesses do have a black/white wire that is the “Kill” wire. Are you sure it’s blue/white and not black/white?
@@MiniBikeMike My CDI harness had 3 extra leads with plastic plugs connected with wires 1 green and 1 black/white, so I cut 2 of them off and connected the other set of green + blk/wht to my kill switch on handle bar. The coil wires were already wired into the harness and had a sleeve on them, thats how this unit came packaged. And I checked the other wire from the CDI harness, it is a blue/white, so there were 2 of these that were in the cdi wire set for some reason, what it does I have no idea. the harness CDI plastic plug is good and fit in the CDI port and is connected. For now, one loose blue/white on cdi harness set, one white, one yellow, one green/red on the engine harness. And I cant start the bike, tank and muffler not mounted yet. Want to get rectifier wired in before I start it.
Question for ya I know this video is older but I have a stator with two yellow on a 2021 Apollo 125cc dirtbike how do I hook up retifirer for lighting having troubles might you be able to give me some insight please and thanks
“Most” 2-yellow wire setups are full wave and require a full wave regulator. For the wires, one of the yellows gets connected to chassis ground. The other yellow gets connected together with the yellow and white wires in the harness.
@@MiniBikeMike thank you I will try this this weekend been trying to figure this out for weeks lol and thank you for a speedy reply have a great weekend let’s go oilers lol
I have 8 AC v at idle and 50+ AC V at high rpm Only getting 3 DC v from regulator and 10 DC v at high rpm. I have yellow and white from stator to rectifier ,12v to lights and ground to frame. Any suggestions?
Hey mike. Followed the directions to a t. My lights are incredibly dim at idle. Any pointers? Ive been struggling for a while😊 now. I do have an aftermarket stator/lighting coil on the bike as i killed the lifan one in my struggles. Getting tired and ready to give up to be honest.
@S7Sking oh I got it figured out a couple months back. Needed an original lifan stator and now my lights are nice and bright at all rpms and still no battery.
Don’t know if you’ll see this, but is it possible to wire up the brake light to get brighter when front or back brakes are engaged? Also without a battery?
Hi Mike, iv a stator that has just the neutral light option on the black grommet on the box (not for all the gears) and that wire is green and red. If I were to wire in just a neutral light on the pit bike the neutral light would have two wires. What wire would I need to tap into for it to work? Thanks.
@@MiniBikeMike thanks for your reply. So the red/green single wire on the stator into the black grommet for the neutral indicator is ground. The potential neutral light would have black and red wires. Correct me if im wrong, so the red/green wire would connect to the black on the neutral light and the red wire from the neutral light would feed into to which wire then? Yellow? Or which wire? Thanks once again?
@@jonjeny Let’s start from the beginning. Does your engine have a neutral switch? Does the green/red wire connect to a round black plug that is to the top right of the stator? If not, you’re not going to get a neutral light to work. If you do have a neutral switch, the green/red wire connected to it should run up to the headlight and connect to the ground wire of your neutral indicator light. The other wire of the neutral indicator light will hook to whatever wire you have that is 12v hot, with the key on or when engine is running.
@@MiniBikeMike it's a 70cc kick start pit bike with no headlight and no key. It does have a neutral switch. Yes the red and green wire does connect to a round black plug at the top right side of the stator. The bike doesn't currently have a neutral light, I'm looking to potentially get one to wire in. Thanks again for your replies.
I just got my black lifan 125cc followed all the steps to just make it run started on the 2nd kick but can't lower the idle its stuck on full throttle I even removed the idle screw and still got high idle can you help or anyone in the community thanks
Sounds like the slide was installed in the carburetor 180° out. Take the cap off the carb and pull the slide out. Make sure the groove in the slide goes over the pin inside the carb barrel.
I just bouhgt lifan with yellow and pink wire coming from stator. I only got about 6volts from recifier(i have tried two 12v recifiers and one was brand new. I read from internet that there is half wave and full wave stators and i am pretty sure that half wave stators needs half wave recifier and full wave stators needs full wave recifier. I think that my lifan is full wave because light coil is not grounded on engines frame(read that from internet). So normally lifans come with yellow and white wires? And are yellow and white wire stators half wave and needs half wave recifier? If thats right i may need to buy full wave recifier to my full wave lifan. The reficiers that i tried was from my old chinese motor with yellow and white wire and if they were half way recifiers then they dont work with full wave stator?
@@zingzong3812 I’ve had absolutely zero luck with stators that have the pink wire. I don’t know how they’re wired, but I’ve never gotten one to work correctly. My advice is to spend the $20 on Amazon and buy a new stator setup with a white and yellow wire.
Google can probably explain it better than myself, but the half wave is just that….only half of the AC wave is converted to DC. The other half is sent to ground, if I’m not mistaken. It’s an inefficient system, but cheap. I believe the charging coil is split between 5 windings, 3 are output thru the yellow wire, which is intended to power the headlight. The other two are sent to battery. I believe a full wave system sends all AC power from both sides of the wave to the battery and all electrics are run thru the battery. If I have all this incorrect, I apologize.
The harness kill wires are typically green wire and a black/white wire. If you’re using a kill switch/button with two wires, it doesn’t matter which wire connects to which wire of the harness. The switch is just opening a connection between the green and black/white of harness. If your switch / button has one wire, that wire has to go to the black/white in harness.
@@MiniBikeMike ok thank you, and i don’t think the colors of the 2 wires my kill switch has which are the green and then black with gold stripes i can connect those to the harness wires that are green and another wire that’s black with white stripes right ?
@@Markonacr250r The semi-auto have skyrocketed in price over the past couple years. Hard to find one under $500. On the other hand, the unbranded Lifan manual is like $230 and includes carb, CDI, etc.
Oops from the motor there is no white wire but there is a pinkish colored wire that does not match up with the wiring harness so im guessing it does what the white one would do. That leaves a green and brown striped wire and a green one witch I think is the neutral switch
I have never had any luck with the stators that use the pink wire. I honestly don’t know what’s different about them, but if I’m trying to hook up lights, I’ve never gotten it to work with the pink wire stator. So…..if you’re trying to run lights, I’d spend the $15 and get a new stator with the correct wiring. It can be bought here: 12v stator plate amzn.to/3WOMDnh
Thanks buddy ,I’m going to try to use the stock wiring harness on my 68 CL90 if I can’t get it to work I’ll use this method. I don’t think that I could have gotten this far without your help on your videos so thanks so very much for posting them. If you are ever in Cookeville TN look me up dinner will be on me.
@@dannywilmoth6402 We were just in Cookeville in October. Went to a couple of the falls parks. Had dinner one night at Father Toms Pub, had a great time.
We have a lot of great places to eat in Cookeville and Father Tom’s is one of them. There is a great brewery down from there Red Silo good beer and Music. Look me up if you are in town again .
Hello y’all, Mike. I have done exactly what you are showing here, still the max voltage I get from the engine is 8. Do you or anyone here have an idea why and how can I fix it? I have a battery that I’d like to charge. Thank you.
@@MiniBikeMike I’m not sure on that, it’s a generic Lifan 110 gn110 pit bike motor, most use a normal 4 pin regulator but mine just keeps blowing bulbs when you rev it up. I have tried multiple known working ones too Will order half wave one and go from there Thanks Mike
@@MiniBikeMike I had a look unfortunately they don't sell them I would also make my own but I don't own a welder and I don't think one that's just bolted together would be very sturdy guess we will find out
Ok; so when you made your 'T' connection on the yellow wire from the rectifier and connected the stator yellow and headlight on the same wire, you were pulling AC directly from the Stator?
@@JetSkiBuyFixPlaySellChannel sorry may sound a silly Question would I be running the + then for the light from the regulator as well as a think fused + to the battery for charging
Ok Mike if you could give me a quick response..I got my wiring harness for taotao 125 but it doesn’t have a front brake plug,Where can I run the front brake wires from?Can I just plug into the back brakes??Thanks for your thoughts..
@@joseplaisance7451 The front brake switch should have two wires. One is for power in and the other is power out. The power out wire can be hooked to the same power out wire as the foot brake switch.
When you say it would go too your switch instead of your headlight do you mean the negative really need this video to include a switch I’m so lost and I know it’s easy
In the video, the headlight is hooked directly to the yellow wire and the headlight can not be turned off, when the engine is running. If you want the ability to turn the headlight off, install a toggle switch between the yellow wire and the headlight.
@@MiniBikeMike I have a toggle switch with the yellow running too my switch negative ,and the positive for the switch running too the positive on the light and the negative of the light as a ground not sure if I grounded it properly or if I missed something because I had it working then when I went to drive the bike in my yard the lights got bright then cut maybe something came loose I’ll have to check tommorow but I’m wondering if I did something wrong as I ended up not having to use the green or red on the regulator and just the yellow and white hooked up and I made the yellow so it goes to the bike yellow and then added a wire that runs to the negative of the switch I’m using for on off for lights also my bike has no battery in my setup got *update I got it working your video deff helped turns out I had a ground going properly but I dident hook it up too my green wire so when I had it all grounded properly my light dident burn out this time lol
Hi Mike can I pick your brain for a sec? I just tried to start my bran new lifan 125cc it started once and after that nothing I do have spark it has a bran new carb Im stumped at this point
I guess if it were mine, the first thing I’d do is pull the spark plug and check for compression. If that’s good, I’d dribble some fuel in spark plug hole, reinstall plug and see if it fires. If it does, you have a fuel delivery problem. If it doesn’t, about the only thing left to check would be timing.
If you wired light as shown in video, there is no battery. Without a battery supplying a constant voltage, the light will always flicker, due to the stators random voltage output.
@@MiniBikeMike do you use a battery and voltage regulator or one or the other? Also if you are running an ignition switch made within the harness do you need a run switch?
So from engine leads, the yellow is power, the white is a ground? you dont say what the white wire is for? Guessing engine white wire is the ground lead to rectifier that ends up connecting the green wire on headlight and black on tail light
The yellow wire and white wire both come from the charging coil. Only the green wire is ground. The yellow and white work in unison to create the power output.
@@MiniBikeMike im trying to wire my ssr 125 engine so the hwad lihht and tail light will work, i took out the 6 volt bulbs and put in 12 volt. Rather not have to use the rectifier with all this, was gonna run headlight blue/white wire to xonnect with yellow and T in the eed tail light wire also. Do i need to splice in the white lead into all this too?
