When you tried to rotate it, the shaft had no bearings, thus it was scraping against the magnets. Once the end caps bushings are in place, it rotates as it should. Good idea to bench test a starter before doing the re-install. With AMC/Ford/Autolite starters, it is a matter of grounding the case (usually a bolt flange on the aluminum end cap) and applying 12V to the battery cable stud. I have an issue with an AMC/Jeep starter I bought. Will not run - only arcs at the lug when you touch the jumper cable to it. However, when I took the sheet metal bendix cover off and pressed the bendix arm to open those two large contacts, it spins up fine(?) Anyone know if this indicates a direct short somewhere?
