This battery charger is equipped with a self-resetting circuit
breaker. This device protects the charger from temporary over-
loads. In the event of an overload, the circuit breaker will trip
open and after a short cooling off period will reset automati-
cally. This process is known as cycling and can be recognized
by an audible clicking sound.
1. Before charging any battery, make sure electrolyte (battery
liquid) in each cell is at correct level.
2. Set Switch #2 in the OFF position.
3. If the battery is being charged inside the vehicle, use
connection procedure outlined in Section E. Should the
battery be removed from the vehicle, follow the instructions
in Section C, (step 6) and Section F. Plug the power cord in
AC outlet.
4. Set switch to desired charge position 2 amp or 10 amp.
NOTE: This battery charger is not automatic and can
overcharge a battery if permitted to operate for extended
periods of time.
