72 overcharging

An answer has been found.......or at least a solution possibly. I'm going to say cautiously that both cheap voltage regulators were(are) junk. Some day I'll try them out in my '75 D300 dump truck to see what happens.

I had run it the other day when the temp was back down to 9 degrees F. With a resting pre-start battery voltage of 12.6V, it shot right up to 15V once running. Warmed up and idling voltage was 15.1V to 15.3V whether or not I had any electrical loads on it. Enough of this!

I installed a new adjustable VR.

With plowable snow in the forecast, I dialed in the new adjustable VR after getting the engine warm. Right now we're talking 14.10 at idle, 14.3 with a crusty '72 heater blower howling away. Have not run it much but it's snowing hard .......
