charger is different. It employs a circuit that produces an extremely well-filtered d.c.
output. Therefore the charger is able to power virtually any d.c. powered device
(within the unit's rating) without the battery attached in-line (if, for instance, the
battery must be removed for any purpose and a.c. is still available). All but the most
sensitive d.c. powered electronic devices will function as normally as if powered by
a battery. In addition, the current limiting circuitry enables the charger to handle the
high start-up surges associated with inductive loads, such as d.c. motors in radar
sets.
INSTALLATION NOTES
VI) TROUBLESHOOTING
CONDITION
A. Batteries not coming up
to full charge.
1. Extremely discharged
batteries requiring long
recharge time.
1. Turn off all d.c. loads
and allow charger 24-48
hours to recharge
batteries.
POSSIBLE CAUSE
SOLUTION
2. Charger limiting its
output due to overload or
over temperature
conditions.
2. Reduce d.c. load and/or
determine cause of over
temperature state (See
section III B, “Location”)
3. Fan not operating
properly, or filter clogged,
causing charger to protect
against over-heating by
reducing power output
3. Clean or replace
clogged fan filter or
replace fan if necessary
B. Charger continues to
charge at 3 amps or more-
-does not taper back in
charge.
1. d.c load still connected
to batteries. (Not a
problem condition)
1. Turn off main battery
switch to d.c electrical
panel or turn off all d.c.
loads if you wish to
confirm charger will
output minimal amperage
to fully charged batteries.
2. Check for shorted cell
in all wet lead-acid
batteries using a
hydrometer. Replace
battery if cell is shorted.
Refer to manufacturer for
testing maintenance-free
batteries.
2. Bad cell in one of the
batteries to which the
charger is connected.
C. Charger does not
charge.
1. Blown input fuse.
1. Replace fuse with
another of correct value.
Check to see if a.c input
select switch is in proper
position. Check to see if
input fuse value is correct
for input a.c voltage.
2. Charger is not receiving
a.c. input voltage or is not
receiving correct a.c. input
voltage.
2. Using a voltmeter,
confirm a.c. input voltage,
check input connections.
Confirm a.c. input select
switch is in correct position
or correct a.c. connector/
adaptor is installed.
Warning: Do Not replace the gray slotted cap of the fuseholder without a fuse
installed. It will not be retrievable. If this occurs, contact the factory.
