Hi! First post, so I hope this makes sense. I just bought a 73 mach 1. When it was parked a yr and a half ago, the key would start the car, and everything worked,. Now, the key turns on the dome light and nothing else works at all. It will "jump" and run. The horn works, and the hazards work, but the headlights and blinkers do not. There are four fuses that are not blown, but have no power. ....
