2000 F250 SD 5.4 Battery light keeps coming on alt is charging...Help
How many volts is the alt. charging?
The Alternator may charge but it still may have a problem, bad diode, internal voltage regulator feedback, winding resistance, brush contacts bad, flying short or open circuit, just a few things that can happen. Have the system checked completely, some parts stores have an alternator tester in the store. DO NOT remove a battery cable while the engine is running, it may damage the electronics and computer systems, then your headed for a major repair bill.
