Severely discharged

battery, but otherwise it is

The settings may be

wrong. Check the charger

settings.

Have the battery checked.

Circuit breaker cycles

when current draw is too

high. Check for shorted

cables or clips and replace

if necessary.

The battery may not want

to accept a charge due to

recoversufcientlytotake

a charge. If more than 20

minutes, stop charging

and have the battery

checked.

Shut the charger off

but is not charging.

Clips are not making a

good connection.

Check for poor connection

at battery and frame.

Make sure connecting

better connection.

BEFORE RETURNING FOR REPAIRS17.

When a charging problem arises, make certain that the battery is capable 17.1

of accepting a normal charge. Use a good battery to double check all

connections, the AC outlet for a full 120-volts, the charger clips for correct

polarity and the quality of the connections from the cables to the clips and

from the clips to the battery system. The clips must be clean.

When a battery is very cold, partially charged or sulfated, it will not draw 17.2

the full rated amperes from the charger. It is both dangerous and damaging

to a battery to force higher amperage into it than it can effectively use in

recharging.
