PROBLEM

POSSIBLE CAUSE

SOLUTION

The charger is making an

audible clicking sound.

This battery charger is

equipped with a self-resetting

circuit breaker. This device

protects the charger from tem-

porary overloads. In the event

of an overload, the breaker

will trip open and after a short

cooling off period will reset

automatically. This process

is known as cycling and can

be recognized by an audible

clicking sound.

Battery is defective.

Shorted battery cables or ring

terminals.

Severely discharged battery,

but otherwise it is a good

battery.

Reverse connections at

battery.

Have the battery checked.

Circuit breaker cycles when

current draw is too high. Check

for shorted cables or ring termi-

nals and replace if necessary.

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 take a charge. If more than

20 minutes, stop charging and

have the battery checked.

Shut the charger off and correct

the lead connections.

Charger makes a loud buzz

or hum.

Transformer laminations

vibrate (buzz).

Shorted Diode Assembly or

Output Rectifier Assembly

(hum).

No problem, this is a normal

condition.

Have charger checked by a

qualified technician.

POWER ON (green) LED is

not lit. Charger will not turn on

when properly connected.

No power at the receptacle.

Charger is not plugged in.

Poor electrical connection.

Check for open fuse or circuit

breaker supplying AC outlet.

Plug the charger into an AC

outlet.

Check power cord and exten-

sion cord for loose fitting plug.
