BEFORE RETURNING FOR REPAIRS 17.
When a charging problem arises, make certain that the battery is capable of accepting a 17.1
normal charge. Double check all connections, AC outlet for the correct voltage, 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 the full rated
17.2
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.
When an UNKNOWN OPERATING PROBLEM arises, please read the complete manual
17.3
and call the customer service number for information that will usually eliminate the need
for return.
