1968 Complete Electrical Failure

Arlie, there should be a main power line that comes in for the stuff that has power if the key is off and another line or lines for stuff that only works when the key is on, plus all the individual outputs. From your original post, I gathered you had absolutely no power. One thing you can do if you think the problem is a short, with the battery disconnected, is take an ohm reading from the outputs of the fuses to ground. That will show you if you have a short on a circuit. With the power appearing and disappearing though, it sounds like a bad connection or broken wire. The places most likely are the wire at the starter solenoid, the connection at the fuse block, or there is a flat, 4 wire plug under the dash that carries the main power wire into the under-dash harness that might be loose or corroded. Good luck, and let us know what you find as you go along.
