Setting the controls
All of the controls for your charger are located on the front of the charger. Read these
instructions to properly set the charger controls.
Ammeter
The Ammeter indicates the amount of current, measured in amps, that is being drawn
by the battery. As a battery takes on a charge, it draws less current from the charger.
Correspondingly, the meter will show less current being drawn by the battery. When the
current stops decreasing, the battery is charged.
The 2 amp charge rate may indicate some activity on the meter, although the meter
does not have the resolution to display this low rate. For the 2 amp charge rate, a
triangle has been provided. Its accuracy has been calibrated for use with small batteries.
• Percent of Charge
The percent of charge is based on the current drawn by the battery. For this reason,
accuracy will vary with the size and battery type.
LED Indicators
• Full Charge LED - Indicates the battery is fully charged and the charger is in
Maintain Mode.
Battery Type Switch
Use this switch to set the type of battery to be charged; Standard or AGM. Both settings
are for regular and deep cycle batteries. If you are not sure what type of battery you
have, select the AGM setting.

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.
16.3 When an UNKNOWN OPERATING PROBLEM arises, please read this 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.
