PROBLEM
POSSIBLE CAUSE
SOLUTION
The LCD display shows:
BAD BATTERY and
beeps four times, then
shows CONNECT
BATTERY.
The battery is bad or
sulfated.
In the case of a severely discharged
battery, the charger will go into
abort mode. If, after the output
turns off, the battery voltage drops
to under 0.2 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.
There is nothing showing
on the digital display.
The charger is not
plugged in.
No power at the receptacle.
Poor electrical connection.
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.
The charger is making an
audible clicking sound.
Circuit breaker is cycling.
Severely discharged
battery, but otherwise it is
a good battery.
The output clamps are overloaded,
due to a shorted cable or clamp,
or there is too much power being
drawn from the AC line. Diagnose
and correct the shorted condition, or
unplug anything else that is on the
same AC line as the INC-800A.
The battery may not want to accept
a charge due to a run-down state.
Allow charging to continue until
battery has a chance to recover
sufficiently to accept a charge.
If more than 20 minutes, stop
charging and discard the battery.
Charger makes a loud
buzz.
Transformer laminations
vibrate.
No problem; this is a normal
condition.
