SOLUTION/REASONS
Check for poor connections to
battery and frame. Make sure
connecting points are clean.
Rock clips back and forth for a
better connection.
Ammeter may show no activity
at the 4-amp charge rate.
Continue charging battery for
two more hours. If problem
continues, have the battery
checked.
Verify that you are using a
12-volt, lead-acid battery.
Use a shorter or heavier gauge
extension cord.
A sulfated battery will eventu-
ally take a normal charge if left
connected. If the battery will not
take a charge, have it checked.
Continue to charge the battery.
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 and replace if
necessary.
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 tested by a Sears
or other qualified service dealer.
