VI) TROUBLESHOOTING (cont.)
3. Charger output is not
properly connected to
batteries.
3. Refer to d.c. wiring
installation diagram for
proper connection to
batteries.
4. Blown output fuse
4. Replace with another of
correct value (see section
III D, “d.c. output Wiring”)
5. Defective charger.
5. Return for analysis/
repair by servicing dealer
where charger was
purchased or contact
NEWMAR for Return
Authorization Number.
D. Charger repeatedly
blows input fuse with no
batteries connected.
Internal short.
Same as above.
E. Reverse polarity
connection to charger has
caused charger to stop
charging.
d.c. Output fuse and
possibly other
components blown.
Replace output fuse with
another of correct value. If
fuse again blows, return to
servicing dealer or contact
NEWMAR for Return
Authorization Number.
F. High output voltage
measured across charger
output terminals.
1. Batteries not connected
to charger. It is normal to
read 1/2 volt higher across
any output bank when no
batteries are connected.
1. Check for tight
connection of charging
leads from charger to
batteries.
2. Equalize function
activated
2. Check to verify proper
installation and operation
of equalize timer
G. Charger will not stay in
bulk/absorption mode
when re-initialize button
on remote panel pressed
Batteries at or nearing full
charge (Not a problem
condition)
Verify proper operation by
pressing reinitialize button
(on optional remote panel)
and applying a large d.c.
load
C. Charger does not
charge. (continued)
