Question about Ford Super Duty
I have replace alternator twice. I can ground my indicator wire and indicator light, lights up. When I plug it in the alt it dont. I have no charge at all. I have 12 volts at battery temp sensor terminal. If I switch the indicator terminal and the battery sensing terminal, it will charge only if the battery feed wire is disconnected. I have tried an external battery and completely eliminated the vehicle. Still does the same thing.

Rest at ease the 14 volts will not hurt your system idealy your alt will charge at around 14 to 14,5 volts at the alternator and probably have a slightly lower charge rate at your battery at around 14 to 13.5 at the battery this is completely normal
