Solenoid Testing 101 

Perfect video. Length, clarity, important points, and the customer isn't always right. Perfection.

I can do all that already. But it was a real confidence builder to see what another man does. Thank you for putting this video on and speaking the information also.

Thankyou, your technical explanation is very clear and straightforward. Hope to see you on your other lesson. God Bless.

Great you understand mechanics 💪I also fix such issues but customers don’t understand anything so you have to be vigilant about their complain Thank you so much

Thanks 😎 you just helped me save a starter motor from the scrap yard 👍

Wow, great teacher and teaching! We general customers just go to parts store and dealers. The dealer I went just offer to replace my start for a price and refuse to say if they can tell if the starter was good or not.

More videos please! You guys are very informative.

Thank you. excellent information about the ground strap.

Thanks for showing the solenoid should indeed draw in when dismounted from the battery and supplied power. All the other videos I'd seen were testing the solenoid as you had done during the first part - with the starter fully assembled - and now I can see why that can lead to bad conclusions. By bench testing my starter solenoid independently of the connected brushes, armature etc., I was able to confirm it was faulty.

Thanks for this. I have seen solenoids jumping, vibrating and now if makes sense to me that the brushes / commutator had problems. Thanks again,

Thank you for the information, regards from Denmark

I wanna see more videos like this. Very informative. Very professional

Great information and explanation.

Really good explanation and especially your expertise about starters and how they work!! Thank you

VERY GOOD EXPLANATION...THANKS

Great Video, good information!

Very well done and informative.

Very thorough.. little to advanced for me.. but still made sense! Nice job!

Excellent video guys thanks so much!!

Thanks for sharing this video.

Excellent video!!

good video and explanation

Outstanding video... VERY informative and helpful

good video, many thanks

I had a tractor that I almost replaced the starter. After watching this I took the starter apart and put it back together. It runs again. Thanks.

So interesting lesson

Good video. I just took apart my starter and gave it a clean and this explains why my brush wires looked like a rainbow! The problem was the fuse on my starter keeps blowing, like it's going straight to ground and bypassing the motor. I'll reinstall it tomorrow and see if a cleanup did the job, it was a bit gunked up, but not VERY bad..

Good stuff thanks

Great explanation sir

It is a draw back for sure, but what can you do? We will not share anything on RU-vid that hasn’t worked for us time and time again. This starter is toast and it has nothing to do with the Solenoid the person wanted to replace. Thank you for your support 👍

Thank you. I'm subscribe on your channel right now . Greetings.

Good job.

Ok thanks i really grabed alot i love the video

Thank you so much

Thank you boss.❤

Great video! Thanks for taking the time to educate us. It's always great to see and hear from pros. I'm working on a delco 28mt I see it's obsolete is there a problem with the design or did they just move on and stop making it?

good job

thanks

I love it

شرح مفيد ولو كان مترجم للعربى كان NICE EXPLAINED IS THIS MAN STILL ALIVE

Nice

Excellent video. Why do some starters though go out repeatedly? I have a 1981 Mercedes 240d diesel and have replaced the starter in the last 2 years 5 times. The ignition is also replaced a year ago to make sure that wasn't the problem. I am getting starters from O'Reilly's and often when you put the starter on the first couple of times you can hear the starter motor spin but it won't engage the bendix gear with the fly wheel. The last starter I got from them was a rebuild from Wilson. It lasted 11 months and then at a gas station it just stopped working with no warning. I got the car going though with a push start and popping the clutch and got to my destination. All of their starters are rebuilt using Bosch starters. Even the last one rebuilt by Wilson that I bought at O'Reilly's was a rebuilt Bosch. AAA said the battery was good and the wires were good. When I took the starter down to O'Reilly's they put it on a machine and it would not even click. I put another store brand O'Reilly's rebuild and two times it spun the motor but would not engage the bendix gear. Then after the 3rd time it finally worked but it still sounds underpowered compared to the Wilson when it was working.

What is the video called for your amp draw talk , i searched amp draw solenoid , , but brings up a list of a few , I've started with ' Solenoid Not Working On Early Delco Starters' , but re-watching this and thought I would ask

This Is a great information sir.but how about if the solinoid doesn't draw in?what could be the problem?

Thanks for the educational stuff, quick question for you.. my car starter works fine but at the end of the crank up makes a kharrr krrkk sound.. wondering if the entire starter needs replacing or if we can just do with replacement armature

If I understand you right . Both the starter and Solinoid must have a good ground together get the Solinoid to work. I'm talking Mercury outboard. If I bypass either Solinoid or battery. They work. This has been a two month work shop for me.

nice

Should the Pull-in Winding and Hold-in windings each have such low resistance? Ohm tested them both on a good starter, each reading was .4 ohms.

Is there a possibility that a starter can put out the volts but have trouble turning over?

How do you wire the solenoid for it to run? I bought a new one and try to ran it and it didn’t work

Hagmeister ty, In my quest... if i see a gd secondhand starter this the same same, and has the number of teeth and the mounting holes are the same centre to centre would the be right to purchase specially as its half the price of Auto Parts Suppliers, notice they have two dif brands but the specs are the same as recommended for my vehicle

I live in Minnesota and I had a problem last winter with my starter on my 93 Chevy. When starting in the cold weather all it would do is spin. Thought it was a bad bindex or sticking, so I bought a rebuild starter and it worked for a couple of weeks and back to the same problem. Summer comes and no problem works great. Now problem returns now that is getting colder out side. I replace heavy cable going from batter to the starter and checked all the ground cables. and the battery is new. Can't figure it out. Any suggestions?

V NICE

I've changed starter n I believe now it's the solinoid but I'm getting smoke in cab .what can it be.when I get it started I hear grinding n then I see smoke in cab .what can it be.?

Something caused the started to be overdriven as evidenced by the armiture flying off. It it possible that the solonoid was staying engaged and keeping the pinion gear in contact with the flywheel. Either way your right they need a new one.

thats okay your sharing thats knowing.

culd it by posibel to use a alternator ore starter motor ass a magneto? I have a problem I use plazma ignition aperantly baterry has 14-15v put gets no amp faster starter motor turning bether spark but dont know why my alternator stop working aperantly alternator light come ON and stay's ON until I go higher rews so I dont know how bypass that voltage regulator I have small GM alternator 1small fiald wire and 1 big lead to baterry positive. that dual/plazma ignition is strange staff. does the dummy light size has somthing to do with it? culd I bypass that dummy light and simply put thise 2 terminals on alternator together because Im not shure if that is back charge Europ delco remy alternators are diferent from USA delco so Im puzelled why that baterry has no amps even tought evry thing ells works.

Should the small terminal on solenoid that goes to ignition have continuity to ground when the key is not being turned?

Thank you for your good video, but recently i took my car to a mechanic to do some work after one week the starter seems week to crank... I am suspicious........ what you think?

Is called a commutator which is apart of the armature... and if you replaced the brushes and sanded the commutator a little to get rid of any high points as well as sanded the ground contacts on both points than the starter motor would still work for some time but could go out .. could work for a good while seeing as some of the broken comm bar was still there to energize that section of the motor windings.. as long as the brushes dont get torn up by the broken spot and the thing would work fine because the opposite side of the commutator would still propel the armiture enough to start it spinning.. that is if nothings shorted together on it.. those old motors had a bit more beef under their balls than todays motors because of all the cut corners and penny pinching...

Is it normal positive terminal of battery has contenuity with starter motor casing

How many pounds or ounces of pull should it take to pull the starter drive out to the position where it would engage the ring gear? The starter is in a 1993 GMC Vandura with a 5.7L engine.

Hello there- I just replaced my starter in a Chevy 1990 4.3 V6. The problem is that after replacement, I cranked it for the first time and all was well. The second time that I tried to start the engine, I had no power on the dashboard and my battery poles literally melted. I don't know what to do....Any Ideas?

I would like to know why people don't rebuild alternators and starters locally anymore. There used to be an old man around here that enjoyed doing it. Is it a bearcat to do? Have the replacements become cheap enough that people just gladly exchange the old parts for new and never consider rebuilding it themself or locally?

Could you show me how a Folo-Thru bendix starter drive works? This is on an old 1948 Willys Jeep, CJ2A with an Auto Lite starter with a tag that reads, MCH 76203 10N, Also stamped on the body is Rebuilt - 3382

The bar on that armature threw a bar because the brushes wore out and when the starter stalled it over heated that bar. Aftermarket cheap brushes were the cause of all the damage!

Hello sir I have unusual question. I have gasoline engine and I try kinde of finde disel starter motor with planetary gear set . I found one nearly identical even tought its from different car . I managed to use all 4 insulated brushes and use thick cabels I managed to reverse direction for the starter motor because me gasoline engine turns oposite way. Now me problem is the reduction gear has couter grewes drilled and the clutch on the bendix turns the oposite direction. Is it posibel to disabel that clutch function? Ore modify that bendix in any way? I need badly high torque starter motor because I like me engine advanced ignition timing for bether fuel economy. So any help please? Im not shure how I shuld atach the selenoid he does not realy work . It is a magnet starter motor so I have dificulty finding parts . I have years problems with starter motors expecialy in winter time they do perform porely . And I wanted to know why some starter motors have 2 and 4 brushes ? Can they actualy be 6v starter motors if you actualy remove 1 pair of those brushes? Me curiosety get the bether of me . But in the old days they suposedly used relays ore selenoids if Im not mistakeing the old delco alternators to excite field coil in the alternator is that correct? I do have after all delco starter motor with S and R terminal selenoid so culd that thing tehnicaly excite the alternator with diode? This is just tehnicaly speakeing of course. How do you actualy test polarity be coils for starter motors? What will it actualy do to the alternator if you for some reason reverse polarity be those starter motors.

Hail l am from Rodrigue island ,I have an old Mitsubishi and when l start ,the starter continued running even l stop the contract ,to stop l must take out the positive cable on the battery , could you help me understand the problem

Got an,issue with starting, sometimes the motor starter wont turn over, though not tech tests conducted yet it starts well 98 percent of the time, so battery and starter are in good shape. Can you suggest the solution with only that scarce info.. Gracias por todo.. Aufwiedersehen.. Terracan crdi 2.9 SUV..

Was there a spring in the solenoid?

❤❤❤

You need to have better lighting so we can actually see where your leads are connected, or tell us which terminals are being used, other than that it is very informative

Frry good

First, how much power(ampire) does this starter consume? Second, is it possible to operate this starter for 20 continuous minutes?

It would help me if I could see how each wire is connected in a drawing.

Was hoping you were going to remove one way clutch.

I like your video, I Resently had a starter taken apart, was full of salt water, dried it out , soaked it with , cleaner , all looked well , put it together, put it on the motor , worked fine, started the motor , few times , then it quit again, ? Why,

Your video is not accurate. You state several times that the solenoid was not seeing a good ground yet you can clearly see at the beginning that the solenoid is drawing amps because of the intense sparking. If the grounding was interrupted, there would be no sparking. What more likely happened is that the physical damage to the motor caused the solenoid lever to become jammed in place, thus not allowing movement of the solenoid plunger. That is why there was no click yet there was amp draw. Then after you removed the solenoid and tested it by itself, you unjammed it from the motor assembly and it worked by itself. So the solenoid was mechanically jammed because of damage in the motor housing, not because of an interrupted ground connection.

Where could I get a new started with a solenoid for a 1978 Rolls-Royce Silver Harry 2

My land cruiser does a single clink if I hit the starter with light hammer it starts

What could be reason starter solenoid damage

I am fedup of my Hilux 5l starter motor after cleaning it and changing the carbon bushes and cleaning the ground connection on that back cap the motor works fine for 24 hours after running the pickup for hours and the switching the engine of and restarting it after few seconds it doesn't work it can't rotate the engine properly

02:24 Is NOT a ground and its a common misconception - All starters i know have no ground, ground is via bolt to engineblok

Why are you testing with 24 V rather than 12 V?

Hi starter runs continuesly even after the ignition is off

you are wrong that braided copper wire is actually positive current that flows to the brushes and not negative and the brushes that are grounded are actually soldered on the case itself so what you were doing when the light turned on was actually shorting out the cables that's why every time you touched the positive it'll drop so much current and you say you have 30 years in business well i have 3 years repairing corvette wiper motors, headlight motors and starter motors and you sir are wrong about the braided strap being ground.

Mine just click

Let’s be honest, 8 out of 10 times it is just the solenoid.

Can u watch my latest uploaded video and confirm is my starter motor?

After seeing the whole video… this is a great video… but NOT what the title claims… But in typical RU-vid and Google fashion … I can’t edit the goddamn comment Hagemeister… thanks… And my apologies… But SOOOOLE… SOOOOLE LENOID

Your camera is too far away… have no idea where you connected tester snd power wire on solenoid test.

Soooooooole le noid… sooole…sole…sole… Len…noid Not sell le noid

Time waster….. SOLE LEN NOID TESTING…. not The history of starters

Good viedo! Thank you!
