PROBLEM
|
POSSIBLE CAUSE
|
SOLUTION
|
|
A battery is connected
but the LCD display still shows CONNECT BATTERY.
|
The
battery clips are not making a good connection.
|
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.
|
|
The
battery connections are reversed.
|
Unplug
the charger and reverse the clips.
|
|
The
battery is severely discharged.
|
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.
|
|
The LCD display shows:
CHARGE ABORTED, BAD BATTERY and beeps four times.
|
The
battery is defective (will not accept a charge).
|
Have battery checked.
|
|
Weak
or sulfated plate in the battery.
|
Have battery checked.
|
|
Wrong
battery voltage.
|
Verify
the CHARGE VOLTAGE setting on the charger. Make sure it matches the
battery being charged.
|
|
The
LCD display shows: BAD BATTERY and beeps four times then switches to
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 .2 volts, the charger will reset to the default settings and
the display will show 8V FAST on the top line and CONNECT BATTERY on
the bottom line.
|
|
The LCD display shows
nothing.
|
The
charger is not plugged in.
|
Plug
the charger into an AC outlet.
|
|
No
power at the receptacle.
|
Check
for open fuse or circuit breaker supplying the AC outlet.
|
|
Poor
electrical connection.
|
Check
the power cord or extension cord for a loose fitting plug.
|
|
Other
|
Have the battery
charger checked by a qualified service person.
|
|
The charger is making
an audible clicking sound.
|
Circuit
breaker is cycling.
|
The
output clips are overloaded. Either due to a shorted cable or clip, 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-8A.
|
|
Severely
discharged battery, but otherwise it is a good battery.
|
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.
