12000rpm Tacho Part 1 Wiring 

I was thinking about buying one of these but all the reviews were POOR, mostly because of missing or inaccurate wiring instructions. This video is the reason I bought it. Can't wait for your set-up video, but I feel fairly confident about that. I did see from one of your other videos that if you have a single cylinder, you should leave that setting alone. I have a single, so thanks for that. Also, have you had it out in the rain? I saw a video where someone had fog inside the unit. I'll probably make a breathable cover. THANKS for this video!

Very helpful thank you.

Hi there and thanks for great videos. I'm halfway through installing it on my Ural and have found it so far to be quite straightforward, but only because of your instructions! I have a couple of (hopefully) helpful comments... The yellow/black wire I connected to one of the primary wires going to the coil, rather than wrapping it around the ignition lead. The red lead should be straight to the battery, so always powered. The black wire should go to a switched power source, and I used the wire that powered the backlights of my previous speedo. It's a common problem people have with this speedo that they only wire the black to constant 12V, so it's always turned on. I don't have a fuel sensor, so to stop the fuel gauge from flashing I had to put a 330 Ohm, 1 Watt resistor onto the blue/white wire before connecting it to ground. It reads half full, but that's better than flashing. Connecting it straight to ground kept it flashing for me. I only had one flasher light on my dash, so took leads off the wiring that went to the handlebar switch. My first power on.... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0nfwcrq8vK4.html

Thank you! THis really really helpful

Hello sir, Thank you for the video, you definitely helped me understand how to wire the tach! Luckily I got one with the same wire colours as you and pretty much everything works now except for the Neutral light that seems to be burnt out but I will hook that up to the running lights indicator. However I cannot get the tachometer to work, I have a 1989 Honda CBR600 and I hooked it up to the Blue wire of the Pulse Generator but no sign of movement from the tach. Would you be able to help me out?

Hi great vid. I've got the speedo rigged up all good, speed reads fine up to 30mph then it goes haywire after that jumping up to 70 when I'm at 40 and gets worse the faster I go any ideas cheers Alex

Thanks for the Video, I purchased this speedo for my 2006 V Star 250, Took the old Speedo off and found a mess of wiring that the previous owner has installed ( Im Assuming to add the ape hangers ) so hopefully I can work out which wire is for what so I can wire this in lol

Mine didn't come with a connector on the speed sensor side. Which wires go to which on the 20 pin?

Great work. Huge thanks for helping everyone out.Before I purchase this gauge, I have to ask...do you think this will hold up on a dual sport bike that is subject to a lot of vibration and banging around?

Regarding the red wire (constant power). You mentioned it will cause the needle to get stuck. Will it also cause the speed to not function correctly? Mine sometimes works and other times, the needle will get stuck. The fuel and mph doesn't display. The lights displayed on the speedometer still work properly though (Neutral, turn signals, etc)

Hi there Is the red permanent power supply from battery or from ignition? Also, is the black from ignition or once the bike has started?

Another question. Did you physical solder the black and yellow wire to the pick up post or merge it with a different wire outside the engine.

Probably my last question since I've gotten everything thanks to you. If your bike doesn't have an already made gear indicator on it, how do you wire the gear wires?

Hi, thanks for the video, could you tell me what is meant by the speedo positive, negative and signal please I have the same wiring as you.

My old speedo has just one connection for both right and left indicator as it had just one indication light on speedo for both .How can i wire up with this speedo so that this new speedo lights up both right and left indications separately ?

Just ordered a speedo like this and researching it all to be ready when it shows up. I think I got it all figured out but the fuel sender. I putting this in a buggy with a 2 or 3 gallon tank and wondering what sender are you using? All the ones I keep finding look like they are way too big to fit in my tank but yours looks small enough to work.

Can you please me what to do with the black cable on the speedo? Where does it go?

Hello!! What fuel sensor did you use? My gas tank doesn’t have one so I have to also install one on it.

Hey, thanks for such a great video but I do have one question about it. In the Video, when you talk about the first 3 wires, would the black be the Ignition since the red is running power? I'm wiring up a 2005 Kawasaki Z750s and I think that is the last part I need before I can dive in.

Hi again Do you know what kind of signal it should be for the tacho ? Thanks

Hi, just need a confirmation. So basically on the diagram, the black/yellow wire which says speed signal wire will be directly connected on those pick-up post. I have the same diagram on your link but my wiring has different colors. I'm having trouble which is for the tacho.

great video - how do you set the milage on this tacho?

This video helped me a lot, thanks for that. On my cb360 the Tacho won't receive the RPM signal. When I use test light I can see the light pulsing so I know I have the correct signal wire. This two cylinder bike has two coils and I have the tacho set on 2, for two cylinders but it doesn't read. Is there wasted spark on this bike and should I have left it set on 1 ? Any suggestions will be appreciated.

I connected the black power switch cable to my ignition but the problem is my speedo stays on the entire time, even when the bike is off. Any suggestions that could help me?

Like everyone else, I found your video when researching this gauge. I've gotten everything to work except for the same things everyone else is having trouble with. My 84 Magna does not use a fuel float so I need to ground that, unless you have ideas on how to make the low fuel thermistor sensor work? Also, the bike doesn't have a gear sensor, but it did use an overdrive light to indicate "6th" gear. Due to how this gauge is set up, I can't seem to make it work.

How is the wiring changed to accommodate positive ground?

Hello and thanks for all you do. I still have a problem with the RPM. I have a BMW K75 and tried different things but nothing work. I tried the four wire come from the hall effect sensor (black, red, orange and brown) but nothing.Do you already heard something about this problem ? Thanks again

If you have a two-stroke engine, do you have to set it to 2 cylinders because it ignites every rotation? My 50cc ATV is showing me around 1800RPM in Idle with the default settings

Hi my bike revs up to 12,500 rpm can I still use this tach or will the needle get damaged if my bike reclines. Its a 2007 ninja 250 or ex250

Hello mate I have speedometer like your but I have 2 problem rpm.and setup speedometer I have in setting of circumference 3 number I not sure how set up

FUEL GAUGE Some of the posts on this and other videos state that grounding the fuel gauge wire (blue and white) will cause the fuel gauge to stop flashing. With my ones (3 of them) this was not the case. I have found that you need to ground it via a resistance of between 30 to 500 ohm. Anything more or less wont have any effect. 500ohm displays 1 bar (of 8) i.e. almost empty. 30ohm displays 8 bars (full). (about 330ohm is half full etc.) So if grounding the fuel wire doesn't work for you, try grounding it through a resistor between 30 and 500 ohms.

The pulse generator usually already has a wire coming off it... Can you just use that for the tach? If so... Isn't it pretty obvious to use that for the tach signal since thats what the OEM gauge uses?

HI there. I followed your instructions and everything works like a charm but I have an issue. when I have the battery on the tach it gets stuck at 4000 rpm. when I REMOVE the battery ENTIRELY off of the bike everything works as expected. I'm getting my signal from my pick up coil negative . The bike is a 1984 (OR 1985) YAMAHA XT 250 CDI ignition triple coil (charge,lights & pickup coil)

Which one is the rpm sensor?

Hi Mate, Any idea how to keep the fuel indicator from blinking all the time? I'm not going to use it but the blinking is super annoying.

How did you calibrate the speed??

Great video bud! I have everything working perfectly, besides the tachometer. /sigh. The bike is a 2012 Harley iron 883 sportster. I tried hooking the yellow and black wire to the coil with a resistor. No luck. Also tried hooking it to the crank position sensor. Also no luck. Any ideas? Thank you so much!

Mine lights up but shows no data, just a blank backlight, and no neutral light. The high bean light and indicators work, but I can not get the settings function up despite trying all the methods shown on these vids. Ive double checked all the wirings. Does anyone know if there is a factory reset function on these things?

Great video but why do you say it can damange the tach if you connect it to the coil? Almost all tachometer manuals says you should connect it to the coil.

Hola, podría por favor enviarme el manual si ud lo tiene. Desde ya muy agradecido. Soy de Argentina, compre uno y aun no puedo instalarlo. Gracias

The wiring diagram is not there anymore

I want to buy this meter...please tell me from where can i buy this.? or can you deliver this to me,???

how to speed up the hand when the clock turns on quickly go to the end and return?

which wire is the neutral light

Hi, I still wanted to thank you for the help you gave me for the ducati monster that works fine! I wanted to ask you another advice, I have a 4-cylinder Triumph of 2002/2005 and I have to mount the same speedometer and I have the same problem I had with the ducats, that is, I can not run the tachometer; I wanted to know if I have to mount it the same way from ignition pick-up or that kind of motorcycle since it's infection should be mounted differently ?? thank you so much

Hello, sorry my english but i'm using google translator, i wanted to ask you a question; I have purchased your own speedometer but I can not run the tachometer how can I do it? I have a ducati monster 600 with carburettors and I can not get it running, could you give me a hand? thank you so much

I now got it working and doing the sweep, etc. But the modes don't come up when Ido the on-off 5 secs? Just CCC 000, which I believe is trip milage set? And no mode number comes up. When I try to move on to the next mode, it trips out to begin again? Am I a dickhead or what?

Hey classic Celica I plan on using the same ebay tachometer in my classicCelica, would you happen to still have the schematic for this? If so you can contact me back via mobile, email, or social media. Thanks in advance and you videos are very helpful
