outlet.
Check for open fuse or
circuit breaker supplying AC
outlet.
Check for poor connection
to battery and frame. Make
sure connection points are
clean. Rock clips back and

Unplug the charger and
reverse the clips.
Have battery checked.
Ammeter may show no
activity at the 2A charge
rate.
Continue charging battery
for two more hours. If
problem continues have the
battery checked.
Verify the voltage of the
battery is 12 volts.
Check for open fuse or
circuit breaker supplying AC
outlet.
Check power cord and
