REASON/SOLUTION
Plug the charger into an AC
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
forth for a better connection.
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 that you are using a
12-volt, lead-acid battery.
Use a shorter or heavier
gauge extension cord.
A sulfated battery will
eventually take a normal
charge if left connected. If
the battery will not take a
charge, have it checked.
Continue to charge the
battery.
