damaged equipment and serious injury or death to personnel.
Before performing any repairs on the battery charger:
1.
Loosen the screws (1) that secure the access door (2), and open the access door.
2.
Set the multimeter to the Vdc (Volts direct current) setting. Connect the positive multimeter lead to a positive fuse
terminal (3) and the negative multimeter lead to the negative terminal strip (4). Note the voltage. Repeat this operation
for the other three positive fuse terminals. If no voltage is noted on any of the positive fuse terminals, proceed to the next
step. If voltage is noted, check that the battery isolation switches are properly secured.
3.
Set the multimeter to the Vac (Volts alternating current) setting. Connect the positive multimeter lead to the input side of
the 220 Volt fuse (5) and the negative lead to a clean case ground. Note the voltage. If no voltage is noted, proceed to
the next step. If voltage is noted, check that the battery charger circuit breaker is properly secured.
