Voltage regulator issues

I think I figured it out, I put bushes in alternator around 4 months ago, the little isolator that keeps the brush from grounding to the body of alternator is gone. I believe I probably overtightened it and broke the isolator as it is no longer there. I will reply again when I get a new one and can confirm this is the issue

This happens a LOT way TOO much and it happens with "rebuilts" You have a 50-50 chance of burning up the wiring harness, because "if you happen" to reverse the two field leads, the blue switched ignition "run" feeding one brush is a dead short to ground
