TROUBLESHOOTING 14.
Before Returning For Repairs
When a charging problem arises, make certain that the battery is capable 14.1
of accepting a normal charge. Use a good battery to double check all
connections, AC outlet for a full 120-volts, 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
14.2
the full rated amperes from the charger. It is both dangerous and damag-
ing to a battery to force higher amperage into it than it can effectively use
in recharging.
When an UNKNOWN OPERATING PROBLEM arises, please read the
14.3
complete manual and call the customer service number for information
that will usually eliminate the need for return.
If the above solutions do not eliminate the problem or for information about
troubleshooting or replacement parts, call toll-free from anywhere in the U.S.A.
