99 Grand Am Starer/Wiring problem

[fightincowboy]

Ok so I went to jump my battery the other day and my friend hooked up the connections to the wrong terminals on her car, I didn't notice and when I tried to start my car something shorted out. So I took out the starter and got it checked at Autozone, starter runs fine. Found a wire that had blown apart so I cut the part where it blew and put on a new ground on it. We're not 100% where it came from but we found it dangling near the starter and the other end goes to the alternator. So we looked at the factory service manual and hooked up everything just as it said, but when we plugged in the battery the starter began spinning. There was no key in the ignition however. So my question is how can the starter spin with no key in the ignition, is it bypassing the ignition or is the wiring damaged from the electrical shock?

welcome to AF.

You probly have more then 1 fused link(wire) burnt up.
Plus you could have fried the starter relay and fuses under the hood or the cabin fuse boxes.

Better check those out, and make sure your Re-wire job has the correct wires connected to the right one's.

Your manual will show in the wire diagrams which wire(s) go where andwhere they are coming from .
