TROUBLESHOOTING
The BCM21 charger is designed to provide years of reliable service. However in the
event that it does not seem to be operating correctly, here are some things you can
check.
AC PRESENT LED DOES NOT COME ON.
First make sure any external circuit breaker is ON. Unplug or turn off the external
power to the charger. Plug any other device into the AC receptacle or use a
multimeter to make sure AC is present. Remove the fuse and check for continuity
with a multimeter. If the fuse is open, replace it with the recommended fuse listed
on the label and reconnect or turn the power back on. The AC Present LED should
come on. If it does not, then there is an internal failure and the charger will have to
be returned for service.
BATTERY OVERTEMP INDICATION
If the battery gets too hot during charging, the charger will stop and wait for the
battery to cool sufficiently before resuming charging. If this happens frequently,
particularly in relatively normal ambient temperatures, the battery is likely damaged
or defective and should be replaced.
BATTERY LOW VOLTAGE INDICATION
If the battery is seriously discharged, and the charger voltage drops below 85% of
nominal (ie. 10V for a 12V charger), the charger will alternate between its normal
display and the Low Battery Voltage display until the battery voltage exceeds 85%
of nominal.
BATTERY FAIL INDICATION
If the charger determines that the battery is defective and will not accept a charge,
the charger will stop attempting to charge the battery. This condition requires action
on the part of the user to replace the battery before the charger will resume normal
operation. Cycling the power switch to Off and back On again in any way will reset
this condition and the charger will attempt to recharge the battery again.
CHARGER OVERTEMP
If the charger gets too hot, it will switch to Standby until it cools sufficiently to
resume normal operation.
LOW INPUT VOLTS
If the input voltage drops below the minimum voltage necessary for normal
operation, the charger will show this display. The charger will switch to Standby
and wait for the voltage to recover
