So Im sitting at a stop light about 4 miles from my house in my '69 and it just goes dead. Nothing. No dash warning lights, no lights, etc.
I left the negative battery cable disconnected because the car has a drain and I had removed the quick disconnect as part of my very limited roadside debugging. So before calling it a night once I had the car back in my garage I reconnect the neg cable and now I have interior lights. So then I go to start it and as soon as I turn the key everything goes completely dead again. So I walk away for the night.
Tonight, still dead, that is, I have no interior lights, no headlights, no warning lights when I turn the key on, etc. I check the hot lead on the alternator, the one that comes off the starter solenoid and I have power there. I then go and check power at the horn relay and I have power there also but at some point, the issue goes away again, and everything is back to "normal". Don't know why - all I was doing was using a simple test light to check for 12V at the alternator and horn relay.
I know I had juice at the alternator but can't say for sure about the horn relay since at some point everything came back when I was checking it. Any ideas on where I should be looking or most likely issue if alternator has 12V but nothing else does? Looking at the wiring diagram it appears to me the next major junction is the horn relay.
Thanks,
Jack
