Charging/Gauge Power gremlins

Yes, there is a way to safely run a 60A alternator—it is described in detail at the first link in post #3 of this thread.

A good regulator is better and more reliable than a cheesy one. My preference for the pre-'70 system is this one. It looks a little different to the original, but fits and hooks up directly.
Thank you! Of all places, my local NAPA actually had a square back 36a in stock that I grounded the extra field connector on and with a new voltage regulator it no longer is flickering the headlights or gauge lights. My coworkers are Mopar guys and one of them had an extra IVR4 so I have that now as well, but am yet to wire it in. Will post an update when that is taken care of.
