Troubleshooting
Performance problems often result from little things that you can fix yourself. Please read through this chart for a
possible solution if a problem occurs.
SOLUTION/REASONS
Check for poor connection at battery. Make sure
clamps and posts are clean. Battery may not want to
accept a charge due to excessive run down state.
Ammeter may show no activity at 2 amp setting.
Check AC outlet and extension cords for loose fitting
plug.
Check for open fuse or circuit breaker supplying AC
outlet.
Continue to charge battery for another two hours. If
problem continues, consult a Sears technician.
Check if test switch is in proper 6 or 12 volt position.
Continue to charge battery for another two hours. If
problem continues, consult a Sears technician.
Check if test switch is in proper 6 or 12 volt position.
Circuit breaker cycles when current draw is too high.
Separate the clamps.
Check for worn cables and replace if needed.
Have a Sears technician test the battery.
Correct connections.
Correct Volt/Amp Selector setting.
Crank time varies with the amount of current drawn. If
cranking draws more than 225 amps, crank time may
be less than 5 seconds.
Wait 4 minutes before next crank.
Use shorter or heavier gauge extension cord.
Sulfated battery will take normal charge after a period
of time. If battery will not take a charge, have
a Sears technician test the battery.
