REASON/SOLUTION
Check for a poor connection
to the battery and/or frame.
Make sure connection points
are clean. Rock the clips
back and forth for a better
connection.
Unplug the charger and
reverse the clips.
If your battery does not have
.2V, you must press and
hold the CHARGE ON/OFF
button for five seconds to get
the charge cycle started.
Have the battery checked.
Have the battery checked.
Verify the CHARGE VOLT-
AGE setting on the charger.
Make sure it matches the
battery being charged.
In the case of a severely dis-
charged battery, the charger
will go into abort mode. If,
after the output turns off, the
battery voltage drops to un-
der .2 volts, the charger will
reset to the default settings
and the display will show
12V FAST on the top line
and CONNECT BATTERY
on the bottom line.
Plug the charger into an AC
outlet.
Check for open fuse or
circuit breaker supplying the
AC outlet.
Check the power cord or
extension cord for a loose
fitting plug.
Have the battery charger
checked by a qualified ser-
vice person.
