PROBLEM
Charger will not turn
on when properly
connected.

16. BEFORE RETURNING FOR REPAIRS

16.1 When a charging problem arises, make certain that the battery
is capable of accepting a normal charge. 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.
16.2 When a battery is very cold, partially charged or sulfated, it
will not draw 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.
POSSIBLE CAUSE
AC outlet is dead.
Poor electrical
connection.
Connections are
reversed.
Battery voltage
is too low.
Battery is defective.
