Sheesh I put this in engines' on accident but here goes-
This is concerning a 216 48' Chevy Aerosedan w a 12volt conversion using the 6volt starter. Has never done this before... the starter keeps spinning after I let off the stomper until I disconnect the battery.
Having a bit of a problem (a few but here's the one on deck now)
the braided wires that go to my brushes have grounded and shorted out against the starter hosing on the inside. The copper contacts on the starter foot stomp sylinoid have welded together in the engaged position. I pried them apart. Happened twice and I cleaned and smoothed contacts and it did it again.

Prior to this I painted the pieces of housing, nose cone and end plate. Just now I thought to bare metal the mating surfaces continuous to the bell housing face. I also replaced the brushes and that is all.

I am scared [censored] to run it again until someone has some input. On another note I've noticed that tons of images of starter brushes haven't got any kind of insulation on their braided copper leads so I hesitate to tape mine up. Do you think that my creating a continuous ground from end to end to bell housing will fix my problem? Best regards and do take care, freezer'

ps- all four braided wires are damaged in the same manner. ANY helpful comments much appreciated. fb
