OPERATING INSTRUCTIONS
Ensure that all installation and operating instructions and safety precautions are understood and
carefully followed by anyone installing or using the charger. Follow the steps outlined in “Important
Safety Instructions” at the front of this manual.
Charging Indicators
Red LED – Bad connection, battery not able to accept charge, reverse polarity connection
Yellow LED – Connection correct and charging
Green LED – Battery fully charged
When the charger is properly connected, the LED will illuminate, indicating the inside smart circuit is
functioning to judge the battery status. This procedure may take up to 2 minutes if the battery
voltage is lower than 12.8 volts.
Connecting the Charger with the Terminal Clips
The charger’s output leads have color-coded battery clips (Figure 2) (RED-POSITIVE
and BLACK-NEGATIVE). These connect directly to the corresponding connectors on
the battery posts.
Follow the steps outlined in “Important Safety Instructions” at the front of this manual.
Connecting the Charger with Terminal Rings
The charger’s output leads have crimped,
color-coded ring terminals (Figure 4) (RED-
POSITIVE and BLACK-NEGATIVE). These rings
connect directly to the corresponding
connectors on the battery posts.
1. Remove the nuts from the bolts of the battery
post’s connectors.
2. Position the RED terminal on the bolt of the
POSITIVE battery post connector.
3. Position the BLACK terminal on the
NEGATIVE post connector; then replace the nuts.
4. If there is any problem connecting the output leads, check with a
reputable auto supply store or contact the Customer Service Department
toll-free at (800) 544-6986 for assistance in finding an appropriate
connection device for your particular application.
Note:
ALWAYS disconnect the AC power cord from the AC power outlet before
connecting (or disconnecting) the charger to (or from) the battery.
Connecting the Charger with the DC Accessory Plug
The charger’s output leads also contain a DC accessory plug (Figure 5).
1. Insert the DC plug into the vehicle’s DC accessory outlet.
2. Insert the AC plug of the charger into any standard 110/120 volt
AC wall outlet.
Note:
Some vehicles require that the ignition be turned to the ACC
(accessory) position to acitvate the DC accessory outlet.
