Message: [QUOTE="TurboM700, post: 605648, member: 59"] FYI on battery voltage. Normal driving down the road with lights,ac and heater on high you should be seeing 14.5 and with no load you want 14.7 . This is for all vehicles except VW, Audi they only charge there battery to 14.2 and by doing this they shorten the life of there batterys. A typical automotive battery is fully charge at 12.7 and 12.5 volts if 50% charge and 12.2 its 25% charge. If this was my truck I would take a really close look at the alternator and make sure its not putting out AC voltage and screwing with the computers in the truck. I have seen pletny of superdutys that will loose a diode or 2 in the rectifier and cause weird issues. Just my 2 cents. [/QUOTE]
