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, 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.
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.
