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 battery and replace if
necessary.
2. Remove the source of the overload
or short. Disconnect the charger’s
black (NEGATIVE) 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.
1. On-board DC systems are
drawing between 1.5 – 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 battery 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-10).
2. Clean and tighten or repair all
terminal connections.
3. Load test the battery and replace if
necessary.
4. Red LED
flashes on and
off.
1. Reverse polarity connection
from the output terminals of
the charger to the battery
posts.
1. Disconnect AC power to the
charger.
2. Reconnect output terminals of
chargers to correct battery posts,
Positive (Red or White) charger
terminal to positive battery post, and
negative (Black) charger terminal to
negative battery post.
5. 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.
