PERCENT CHARGED Scale
Indicates battery’s approximate state of charge. Follow the battery manufacturer’s recommenda-
tion for removing surface charge before reading voltage.
VOLTAGE Scale
The voltmeter will indicate voltage (8–6 volts), whether the charger is on or off.
CHARGING SYSTEM Scale
Use to test the alternator. When the ambient temperature is within the range of –40 to +20 o F,
(–40 to +49 o C)alternator output should indicate a reading in the “O.K.” range.
9.3 TIMER Switch
The TIMER Switch is located in the upper right-hand corner. The “OFF” position disconnects the
output of the charger. By rotating the dial clockwise the output is turned on for a duration of time
determined by the number of minutes the dial is set at. The “HOLD” function can be used when
charging times longer than 20 minutes are required. While in the timing phase, the output can be
turned off by rotating the dial counterclockwise to the “OFF” position. When determining charging
time, refer to the Quick Reference Guide and Battery Charging, section .
9.4 RATE/VOLTAGE CONTROL Switch
The charger has a RATE/VOLTAGECONTROL switch, located near the upper left-hand corner,
which controls the voltage and current. ENSURE THAT THE VOLTAGE SETTING SELECTED
MATCHES THE VOLTAGE OF THE BATTERY INTENDED FOR CHARGING. Select the amper-
age rate that suites your application as described below.
SLOW CHARGE
2 AMP: For slow charging low rated batteries used in motorcycles, snowmobiles, lawn and garden
tractors, etc. Trickle charging automotive size batteries.
NORMAL CHARGE
0–30 AMP: For charging automotive style, regular and deep-cycle batteries.
FAST CHARGE
30–60 AMP: For fast-charging automotive style, regular and deep-cycle batteries. DO NOT use on
small, low-capacity batteries. This setting can be used for parallel battery charging. (See section 2.)
BOOST CHARGE
50–80 AMP: For brief, high output charging. Follow BOOST CHARGE ratings (min/max, on/off
times) on charger’s front label. Refer to Quick Reference Guide for more details.
ENGINE START
50–250 AMP: For automotive engine starting/cranking assist only. Follow ENGINE START rat-
ings (min/max, on/off times) on charger’s front label. Refer to Quick Reference Guide and para-
graph 9.4 for more details.
WARNING: AT HIGHER AMP RATES, IT BECOMES EASIER TO BOIL AND OVERCHARGE
THE BATTERY. DO NOT LEAVE THE CHARGER UNATTENDED. REFER TO THE BATTERY
MANUFACTURER’S CHARGING INSTRUCTIONS. USE THE CHARGING TIME CHART IN
THE QUICk REFERENCE GUIDE SECTION, OR THE CALCULATION IN SECTION 11, TO
DETERMINE HOW LONG TO CHARGE.
