TROUBLESHOOTING/FAULT CODES

Error Code Condition
Poor clamp connection.
The charger does not
detect a battery
Battery voltage is under
connected to it.
1.5 V (battery must have
a MINIMUM of 1.5 V to
activate charger).
The battery voltage is
less than 10 V after some
time charging.
Battery voltage is too
high.
Actual charge rate
exceeds selected
charging rate.
The temperature of the
charger is too high.
Cause
Charger does not
recognize the battery.
The battery is defective.
A load may be connected
to the battery.
Battery is not a 12 V
battery.
A load may be connected
to the battery.
Charger error.
High ambient tempera-
ture or poor ventilation.
Solution
Connect battery to charger
BEFORE connecting charger to
AC power.
Ensure battery posts are clean.
Rock clamps back and forth on
battery posts to ensure a good
connection.
Check battery voltage with a
volt meter. If LESS than 1.5 V,
replace battery. (A battery with
less than 1.5V is likely beyond
salvage due to extreme
sulphation or some other
internal failure.) You may try to
boost the battery using booster
cables connected to another
vehicle. This may raise the
battery voltage above 1.5 V
allowing the battery charger to
activate.
Replace the battery.
Do not use the battery
during charging.
Confirm that the battery is 12 V,
not 24 V.
Disconnect the load and attempt
to charge again.
Disconnect the battery and the AC
power; attempt to charge again.
Ensure adequate ventilation.
The charger will resume
charging after cooling.
