[QUOTE="JustinStone, post: 8805079, member: 680824"] After a recent rebuild of my engine, the charging voltage has been reduced to 13.5v from 14.7v. the cables were not disconnected from battery terminals, and everything is damn tight. It will jump from 13.5 to 14.5 or 14.7 sometimes on start-up, but there is no relation to battery temp; it will go back to 13.2 after restarting the car. I replaced the alternator's pigtail connector during the rebuild and repainted the block, but the crimps we're hella tight and the paint was scrubbed off the ground location. Not sure what's going on All batteries tested with ctek charger, and the 5 month old 300 amp alternator keeps the voltage at 13 from 13.2 even while full tilt at 2500 watts. It seems like a regulator issue, but I've switched tunes and the issue still persists? Maybe the pcm isnt getting a good ground, or the battery to block ground wire needs to be replaced. [/QUOTE]
