About a week ago both batteries died on my truck so I got autozone to check it out and alternator tested bad. Put the new one in (rebuilt 100 amp) and decided to go ahead and replace voltage regulator too and all seemed well till the next day. Been through three different regulators from Advance and today the 4th from Napa. I've never encountered this before but I'm guessing the alternator is bad and destroying the regulator? Has anybody had this happen? The regulator will get hot and the voltage guage will start climbing with the rpm's untill it finaly ends up at max. Had to turn the headlights off from fear of blowing them and the heater fan was really spinning till I shut it down too.
