72 Chevy starter....

Greetings all. I posted a subject about 2 weeks ago concerning my trucks inablity to turn over. I have not had much time to deal with it, but had time today.

I went out to the truck as usual and tried to turn it over. Nothing. No clicks, no whirrrrrsss... nothing. The battery had a full charge, and everything else looked fine.

I then placed a screwdriver across the - & + sides of the solenoid, and it began whirling just fine, but it never engaged to starter. I then went in just tio see if this made any difference, and when I turned the key, the first signs of life were evident. The ignition engaged, and the truck went through all the motions (it sounded so good, I expected it to turn over at any moment) of starting, but didn't start. I then took the key out of the ignition, tried to start it agian, and nothing. I then went and did the screwdriver trick again, and it tried to turn over again. Key out, and then in again, nothing. Screwdriver trick, and she tries to turn over again. I have completed this test several times and have gotten the same result everytime.

Anyway to isolate the starter or motor with the info provided?

What do you mean when you say, "it tries to turn over?' ....is the starter engaging, and not turning or does the starter spin without engaging?

When you shorted it out with the screwdriver, was it the terminal that the cable is on and the one right below it, or the one closest to the block.
If you short to the one right below it, it will just spin and not engage. If you go to the one closest to the block, it should engage and spin. If it does not when you go to this one, either your starter is weak or your motor is too tight. Can you turn the engine by hand?

starter..

I touched the screwdriver to the 2 largest post on the starter. I heard a sound as if something were "spinning". Then, when I jumped in the truck to try to start it, I get everything but the truck actually turning over.

You need to cross between the large post that the battery cable is connected to and the small post closest to the engine block. Usually has a purple wire going to it. That should make the starter spin and engage.

If it just clicks or just spins and doesn't engage, the solenoid needs replacing. Probably best to rebuild or replace the whole starter, if this is the case.

That is, if your motor is not seized. Try turning it over by hand 1st to make sure. It sounds like this vehicle has been sitting a lot.

driven a lot

I was driving the truck almost daily until the day it wouldn't start. The motor was just rebuilt, but I can turn it by hand. And it has started intermittantly. I will pull the starter and have it looked at. I think this is where the problem lies.

Thanks for everyones help,

ns
