ok, so this happened to me 4 times yesterday. this hasn't happened at all during the week and a half i've had my truck up and running. turned on my truck like normal, then hit the head lights and the truck shut down. after that, my ignition wouldn't do anything, the lights in the dash that usually come on briefly wouldn't and the starter solenoid wouldn't even click. i get out, jiggle the positive cable to the starter (which has a short in it, i know) and then start the truck up and it works fine including the lights! how are the lights linked up such that it would trigger the positive cable to fail, and how are they connected such that the injection pump cut-off solenoid is tripped? i don't understand the connection. i need to basically redo all of my battery wiring, which i think should fix the problem, but i just want to know why headlights would cause this problem.
