My truck won't start and it all began with a rusted front brake line! I had one front brake line bad and fixed it then discovered the one next to it was also bad and in the process of fixing that line I accidentally shorted the line to the positive battery terminal and got a little zapping for a couple of seconds. After getting the line installed I went to start the truck and only got clicking at the starter. Took off the negative battery cable and cleaned it and the truck started once but wouldn't start again. So I took out the starter and even though the old one tested good I went ahead and replaced it since it has 180k miles on it anyway. Just got the new one installed and not surprisingly the new starter is just clicking like the old one.

I am at a complete loss. I checked the starter cable and am getting a bit over 12 volts so it appears to be getting full power. I took the new battery out of the Roadrunner to try it and still just clicks. Everything power item seems to work fine. I can't fine any blown fuses. Can anyone think of anything else to look for or to test??? After fighting the Roadrunner's no start problem for so long I am beyond sick of car issues and am out of patients. I would really appreciate any ideas!
