REASON/SOLUTiON
Have the battery
checked.
Circuit breaker cycles
when current draw is
too high. Check for
shorted cables or ring
terminals 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
sufficiently to take a
charge. If more than
20 minutes, stop
charging and have
the battery checked.
Shut the charger off
and correct the lead
connections.
No problem, this is a
normal condition.
Have charger
checked by a qualified
technician.
