9.3 RATE/VOLTAGE SELECTOR SWITCH
The charger has a RATE/VOLTAGE selector switch, located at the top
center of the charger which controls the voltage and current. Ensure
that the voltage setting selected matches the voltage of the battery
intended for charging. Select the amp rate that suits your application as
described below:
10 AMP: For slow-charging low-rated batteries used in motorcycles, snow
mobiles, lawn and garden tractors, etc. Trickle charging automotive size
batteries.
30 AMP: For fast charging automotive-style, regular and deep-cycle
batteries. DO NOT use on small, low capacity batteries.
50 AMP BOOST CHARGE: For momentary high rate output. Refer to
charger front panel for time duration.
100–200 AMP: For automotive, engine-assisted cranking-starting only.
Refer to section 9.4.
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
SECTION 11 TO DETERMINE HOW LONG TO CHARGE.
9.4 ENGINE START
The charger’s capacity to provide a high current is suitable for starting
a vehicle that will not start due to a depleted battery. With the RATE/
VOLTAGE selector switch set to 30 AMP, charge the battery for 5 minutes.
After 5 minutes of charge, select the ENGINE START position and engage
the vehicle starter.
If the vehicle does not start after 3 to 5 seconds, release the starter, return
the charger to the 30 AMP position, and wait for another 5 minutes. If the
engine fails to start after a second or third attempt, disconnect the charger.
Before replacing the battery, use a battery tester to test it.
DO NOT attempt to start a vehicle without the battery properly installed.
Damage may result to the vehicle’s electrical system.
