Is the truck totally dead electrically or do you still have headlights? If it is totally dead I would look for a blown main fuse or fusable link. If you still have lights I would look for a bad solenoid, starter problem or low battery. If you try to start it and the lights stay bright look at the solenoid. If the lights dim down your battery is low or you have a starter problem. I dont know if your other problems are related but a short heavy enough to blow a main fuse would play hob with all your systems. |
