Voltage regulator issues

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
Thank you all for the help I appreciate it. Its all fixed now, I just installed a reman alternator instead of waiting for parts to fix old one, still will keep it in case if this reman ends up being junk. I've put a few hundred miles on it now with no issues.
