I have a '73 350 w/ Auto Trans. Tonight while driving along, the car cut off, the headlights went off - no power at all. I coasted for a ways so I could get out of the way - after about 30 seconds - power restored and the car cranked and ran fine. I was running AC, radio and headlights. I turned off AC but it happened a 2nd time while sitting at a stop light - power all shut down - then about 30 seconds late - all restored. I have had it happen in the past when it was raining - radio, headlamps, windsheild wipers and AC running.
I figure that there must be a short somewhere and the system is getting overloaded? Any ideas. I would love to fix - it is kind of dangerous.
Thanks, Chris
