charging issue... AGAIN!!
so i was out side before and letting the truck idle after driving, and out of no where a strange high pitch noise came through the speakers. i looked down at the vlotage meter in the cluster and it was pulsating and seemed like it wanted to move down to 18v. i tuned everything on, lights running lights, hit the brakes, radio, defroster and hazards. nothing happend and it continued to make the noise for about 30 seconds after than stopped and voltage meter dropped down to 14 again!!!???!??!??! im so far confused and am getting sick of electrical problems! some one please help! thanks james

ok so i was looking around and from what i can find trucks pre 92 have external regulators either on the fender or firewall. 92 and up have the regulators built into the ECM.

lots of these trucks have grounding issues. a buddies truck was having issues like yours, we added an new ground to the rad support and that cured it. another issue that we found at the same time was that his battery had a film on it, and we were getting 8 volts from the battery case to ground , maybe that was screwing up the pcm . ithink the pcm regulates the alternator on the 93 . good luck
