It would help if you would tell us more about the charger, Irv. But if it's a
basic buzz box, like my old Schumacher, then I'd guess it's a bad (open) diode.
Mine came to me well used, with an open diode, and I repaired it with a diode
block from an old alternator core. It's worked fine ever since.
