Brrty light on
batteries charged, alternator working....idiot light on dash is on, where do i go next? 7.3, manual 6 spd, 4wd, 431K miles.
I have to ask, but by saying the alternator is working, do you mean spinning or actually charging and you have more than 13.5volts at the battery with the engine on? If the light is still on the dash, look at all the wired connections for corrosion or splits and frays to the alternator, and battery.
