POSSIBLE CAUSE
Check for poor connection to battery and frame.
Make sure connection points are clean.
Rock clips back and forth for a better connection.
Correct connection.
Replace the battery or try using a manual
charger to bring above one volt.
Make sure nothing is touching the control panel,
then unplug the unit and plug it in again
Reset the charger by unplugging it. Select the
desired charge rate and battery type again,
if necessary.
If the battery is in a vehicle, turn the headlights
on for a few minutes to reduce the battery voltage
and try charging again. Also try a lower charge
rate selection.
A sulfated battery will eventually accept a charge.
Continue charging for a few hours. The charging
(Yellow) led will blink. If not, have the battery
checked or call customer service.
No problem; this is a normal condition.
The settings may be wrong.
Check the charger settings.
Have the battery checked.
Circuit breaker cycles when current draw is too
high. Check for shorted cables or clamps and
replace if necessary.
The battery may not want to accept a charge due
to a run-down state. Allow charging to continue
until battery has a chance to recover and take a
charge. If more than 20 minutes, stop charging
and have the battery checked.
Shut charger off and correct the lead connections.
Check for open fuse/circuit breaker supplying AC outlet.
Check power cord and extension cord for loose fitting plug.
Check for poor connection at battery and frame.
Make sure connecting points are clean.
Rock clamps back and forth for a better connection.
