TROUBLESHOOTING
Problem Cause Solution
1. Red LED stays
on for more than
24 Hrs.
1. One or more defective or
damaged cells.
2. Charger has reduced its output
voltage below the normal level
due to a DC overload or a DC
short.
3. On-board DC systems are
drawing more current than the
charger can replace.
1. Load test the batteries and
replace if necessary.
2. Remove the source of the
overload or short. Disconnect
the charger’s black
(NEGATIVE) ring terminal from
the battery. Reapply AC power
and the green LED only should
now light.
3. Turn off all DC equipment while
charging.
2. The red and
green LED’s stay
on for more than
24 Hrs.
SEE NOTE BELOW
1. On-board DC systems are
drawing between 1.5 – 3.5A.
2. One or more defective or
damaged cells.
3. Extremely low AC voltage at
the battery charger.
1. Turn off all DC equipment while
charging.
2. Load test the batteries and
replace if necessary.
3. Apply a higher AC voltage
source or reduce the length of
the extension cord.
4. Check battery manufacturer’s
specs on battery charging.
3. Green LED stays
on when the
battery is known
to be low.
1. Open DC output fuse.
2. Faulty or contaminated
terminal connections.
3. One or more defective or
damaged cells.
1. Replace DC output fuse with a
Bussmann (AGX-6).
2. Clean and tighten or repair all
terminal connections.
3. Load test the batteries and
replace if necessary.
4. Neither of the
LED’s turn on
when the AC
power is applied.
1. No AC power available at the
charger
2. Component failure
1. Connect AC power or reset the
AC breaker on the main panel
2. Return charger to the Guest
Service Dept.
Note: Battery size may be large enough to cause the battery charger to not transition
to float stage due to the batteries internal resistance. Hot ambient conditions will make
this condition worse.
