sixxty7, sounds like you have a short from positive juice onto your purple S wire somewhere. From the battery cable or the other red wire. I would go in yet again and inspect all of those cables with a fine-toothed comb and a bright light. If one shorts to the metal tube (if it's grounded), you could make a giant metal-melted mess, maybe start an insulation fire, and destroy your battery. In my opinion, there's no way the wires just being that close together, insulated, can inductively transfer enough current to energize the solenoid.

6t7gto and george k, thanks for that line of thinking about mechanical hanging up making the starter not stop. 6t7gto, you didn't hijack the thread; this could have been closely related. I just checked and the snap ring is fine, the starter parts all look good and the solenoid looks good too. I've disassembled and reassembled it all. It runs fine on the garage floor; 15 times so far. Since the "starter won't shut off" problem only happens with the starter in the car, I've concluded the starter gear is probably vertically too close to the flexplate, making it bind too tight for the solenoid return spring to pull it back out while running. I'll do the paperclip check advised in numerous other starter posts. I have a single 1/16" shim in there so far; this has seemed to cure a hot start problem that occurred earlier with no shim.

I've seen so much good advice in many of these posts from george k he should be called "master guru" or something...
