A. Trouble-Shooting Static Rectifier Chargers
A common problem is low output voltage in chargers that have copper oxide
rectifiers in the control circuits. Copper oxide rectifiers (and to a lesser
degree selenium rectifiers) have a tendency to deteriorate after long use,
causing a reduction in output voltage. When this condition occurs,
rectifiers should be replaced with silicon rectifiers, which have a slow aging
rate.

rate.
Oscillations in output voltage can occur in some types of battery chargers
during light or no-load conditions because of resonance between the battery
and the charger. These oscillations can be damped out by connecting a
small load resistor (about 100 watts) across the output of the charger.

Always refer to the manufacturer's service manual for detailed instructions
regarding operation, maintenance, and care.
