- It's always best to test a starter in-vehicle, however, some are very difficult to get to. On some, testing in-vehicle would be near impossible. In cases like these I like to bench test them. If I can get them to fail then I can feel comfortable putting a new one in and covering everything back up. Otherwise, if they will not fail, then I will go through the effort of trying to test the wiring while everything is open.
Cool. You packed lots of valuable information in this video.
It's like a comprehensive mini seminar on Starters.
@B Spin Thanks! That's what I try to do. I'm mostly by myself here and I miss being able to share things with others and pass on what I've learned!
Good video, I bench tested a starter and it seemed to work fine, put it on the car and it would spin, sometimes the bendix would jump out but still wouldn't engage the flywheel properly. I've gone ahead and ordered a new starter
what does hitting it with a hammer do?
@bumblbesss It's a trick for any DC electric motor. DC motors are comprised of a bunch of electric coils that each create magnetic fields that actually move the motor. So if one of those coils burn out and the motor happens to stop on that burnt out segment then the motor will not spin. Give it a whack with a hammer and sometimes you can jostle it to a new segment that does work. Then the motor can spin. This can work for fuel pumps, blower motors, etc. You just have to be careful with starter motors because they'll be lined with strong permanent magnets that are fragile. So if you hit it too hard you can damage the starter.
@@eurbanautotech i thought they would get rusty stuck and the hit loosened them up lol. thx for the detailed answer !!!
