I put a voltage meter at the alt. on my 72 and at screeming belt speed, putting out like 18 volts. Disconnected the white wire at the plug and the screeming stopped, at 14.5 volts but the light on the dash is on now. Does anyone have any idea whats going on?
HELP!!!

I don't know much about electrical systems, but on my 69, I was having some over-charging as evidenced by white stuff bubbling out of the battery. Dash lights were also flickering. Then, I heard that screeching sound from the alternator while driving, pulled over, and opened the hood. The horn relay, voltage regulator, and all associated wiring were totally fried and/or melted. The core support got so hot the paint started bubbling on my LH fender. I hope you can figure this out before you have a similar meltdown.

I bought new engine and forward lamp harnesses from M&H, modified for an internally regulated alternator (sourced from a 78 Camaro) and everything works great now.
