The alternator field power (the warning light) shares its power source with the brake lights and the back-up lights. If you have a ground fault in either circuit, it will pop the fuse and effectively "turn off" your alternator.

I think I found the problem. Fuse was not blown. I crawed under the car to take a look at the master cylinder and it looks like there are two wires the go to the presure switch. Although the switch on the master cylinder only has a spot for one wire. I looked in the autoatlanta catalog and it looks like it shows a 2 pole switch and a single pole switch for 1973.
so it look like the previous owner put in a new master cylinder with a single pole switch when it needed a double. Does anyone know why 2 different switches in 1973. From the wiring diagram it looks like it sends 12v to the MC and when you step on the break the presure switch completes the Circuit..... |
