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 10A20A
amp charger can deliver
within 24 hours. The bat-
tery may also be faulty.

unplugging it briefly or
briefly disconnecting the

hicle, turn the headlights

to reduce the battery
voltage and try charging
again.
