After installing my remanufactured starter, it sounds like the unit is failing to disengage once the engine starts. On the bright side, the car now starts. :rolleyes: I pulled it back out to compare with the old unit and didn't notice anything obvious. I just wanted to check to see if there was any possible adjustment on these things. For example: positioning on the engine or horizontal travel adjustment of the starter pinion. I don't see anything of the sort. I have a '94 LT1 and there were no shims on the original unit when I took it off.
It sounds like the solenoid is not disengaging. Did you use the old solenoid, or did the rebuilt starter come with a new solenoid? You will burn up the starter motor if it does not disengage. Another possibility is that the the starter was misaligned and the gears were binding. Before you reinstall the starter, test the solenoid with external 12 volts (battery charger) applied and determine if the solenoid drive mechanism recoils after being energized.
No, the rebuilt one came with a new (reNEWed) solenoid as one assembly. I like your idea about testing the mechanism. How do I do this? The smaller connection post is the solenoid, right? So, I'm guessing I need to put +12V here and ground the chassis (and no connection to the larger terminal post).
To test your starter/solenoid out of the vette.....if you have a batt charger with a "start" voltage feature, connect the ground wire to a starter flange (any place that provides solid contact) and touch the "large" post on the batt with the positive cable. This will "jump" the solenoid switch and activate the starter motor. When you remove the positive cable from the post, the drive should recoil.
