    I think so, I would call your local parts stores and see if they will do it for you.

    Around here Autozone and Murrays both have testers that check all aspects of staters and alts.

    The parts stores will test it but it's not under a load. You could do the same with jumper cables and a starter switch (just a push on/let up off heavy duty switch).

    I've done it without a switch. Just touch the jumper cable to the positive cable solenoid lug.

    I have a question about Norstar engine starters, is it true the engine has to be removed in order to remove the starter? I was told this by folks that did my radiator job.

    Re: bench test a starter?

    Thanks for the info guys, I just removed it and tested it It all works fine on the bench. To get to the starter on my 94 sts I had to remove the intake manifold it is under there. not as hard as it sounds.

    Heres a question tho, after I tested the starter and the drive, and reinstalled it It still just spins, at least thats what it sounds like, and the motor does not turn anyone have any Ideas? could there be a problem with the gear that the starter conects to that turns the crank? it doesent seem to me like it would be a part that would break

    They obviously know nothing about the Northstar. The starter is under the intake in the valley.

    When you bench tested it, did the pinion just spin or did it move to the rear and then spin?

    So when you bench tested it, the pinion moved to the rear but did not spin?

    Hmm, that's strange. Just the way it should. Not sure why it won't do the same when in the car.

    I know its kinda agravating especially when it happened at the same time my tranny went in to neutral when I was driving, So I don't know if they are related or a coincedince but it is frustrating.

    It's possible the one way clutch is slipping under load. It'll feel good by hand but slips when it tries to turn the engine. You can replace just that part but it can be hard to find.

    The gear on the flex plate can get damaged teeth. If you take the starter off again look at them.
