I installed a NORS mechanical voltage regulator (from Halifaxhops) on my 67 GTX today in order to replace the solid state one that was putting out 15 volts+. It’s allowing a charge fine and I’ve about got the voltage dialed in to where I want it but the alternator gage needle is jumping constantly. It was steady before. It’s staying to the right slightly - not going into discharge. I thought maybe it would settle down after the battery was charged back up, from when I started the car. But I ran it quite a while and it didn’t settle down. I don’t see any big jumps on my voltmeter which is hooked up to the battery - just the usual .03 to .04 volts variation.
So what causes amp gauge jumpiness? The regulator points contact were cleaned with electrical contact spray, no-ox applied to terminals, mounting screws are tight. I’ve got a few other regulators I can try if this one I no bueno.
