17. BEFORE RETURNING FOR REPAIRS
17.1 When a charging problem arises, make certain that the battery is capable 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.
17.2 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.
17.3 When an UNKNOWN OPERATING PROBLEM arises, please read the complete manual
and call the customer service number for information. This 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.
