FWIW, I have a smaller Schumacher charger (2/10/50 IIRC) that was given to
me after it died.  Its problem turned out to be diodes (as I think someone
already suggested).  I grabbed a diode plate out of an old dead alternator
and mounted that in place of the original diodes.

I've had to replace a few other items (circuit breaker and battery clips, it
really needs a new AC line cord); but 20 years later those old alternator
diodes are still doing the job.
