1967 1600 Duetto
Yesterday while on a wonderful drive through Napa, CA. The following happens.
1. I see a very brief puff of smoke from under, or near my dash board, to my left.
2. I pull over immediately and turn off everything.
3. I examine under the dash, looking for burnt or hot wires. To my surprise I find nothing. Not even a linger hint of smokey/burnt odor.
4. As I check out what works, and what does not work, I find that I have lost my high beams (these were on when it happened, though it was not even dusk yet). I have also lost my dash/gauge lights.
5. Everything else, including the low beams work fine. We drive home, leaving the lights off and now I'm trying to find the cause. All fuses are good, I cleaned the contacts at the fuse box on all four sets of fuses, 2 for high beams, 2 for low beams, even replaced the fuses with new ones just in case.
My hunch is that perhaps the high beam postion in the steering column switch is bad, and might that be the puff of smoke I saw since nothing else appears to be hot, burnt melted etc.???
Is there a fuse or fuse link under the dash related to headlights that I'm missing?
I have a voltage/amp meter, how can I test the circuit for the high beams, and insure that the steering column switch high beam is or is not working? I'd like to test it before removing it if I can.
Is the fact that I also lost the dash/gauge light a clue? Why are these in the mix, but the low beams are still working??
Any help greatly appreciated. I also requested the wire diagram from Papa Jam. I'll check that out, hoping I can make heads or tails out if it. I've replaced the clutch, pulled the engine, etc. in the past, but wiring is a weak area for me. Circuits can get confusing, but I do get the basics, at least I think...
