TROUBLESHOOTING

POSSIBLE CAUSE
The charger is in tester
mode, not charger mode.
You might have acciden-
tally activated a special
diagnostic mode.
The charger may be
defective.
The incorrect BATTERY
TYPE may have been
selected.
This will happen if the
battery did not reach full
charge within 24 hours.
May be due to a very
large battery or a bank of
batteries requiring more
power than a 15A40A
amp charger can deliver
within 24 hours. The bat-
tery may also be faulty.
Starter motor may be
drawing more than 120
amps.
The battery may be
fully charged or recently
charged, leaving the bat-
tery voltage high enough
to appear to be fully
charged.
The incorrect BATTERY
TYPE may have been
selected.
