Well, my voltage is fluctuating from high 13.6-15.8v at idle. (Lights on, HVAC off) Headlights at idle are now almost flashing bright/dim because of the voltage fluctuation. Pretty sure this is caused by poor V reg quality. Yes, I’ve got an additional ground cable on my alt to the chassis

I put in one of those Eagle Auto Ebay high power alternators in 3/17. That reg died in 11/19 where I replaced with a Hella.

Who makes the absolute best, longest lasting V reg for this car??

I’m between Bosch or a German company called KAE. Any input???

Any idea where to find a Monark long brush voltage reg??
