OFF: This position disconnects AC power supplied by your outlet
from the rest of the charger.
6 VOLT 15 AMP: Used for charging medium and large size 6 volt
batteries, typical application are for crank starting of farm equip-
ment and antique automobiles. Do not charge small batteries such
as used in motorcycles, lawn and garden equipment. (Manual op-
eration.)
12 VOLT 2 AMP: The 2 amp automatic charge rate is recom-
mended for use with small batteries only. If used for maintaining
the full charge level of larger batteries, limit the charge period to a
few days at a time.
12 VOLT 125 AMP START: Used for crank starting of 12 volt ve-
hicles. The engine crank position should not be used for battery
charging, doing so will cause the charger to over heat and thus
protect it’s self by cycling off and on.
12 VOLT 15 AMP: Use for charging medium and large size batter-
ies. This most popular charge rate can operate in either the Auto-
matic or Manual mode of charging. See auto/manual switch.
6 VOLT 125 AMP START: Used for crank starting of 6 volt ve-
hicles.
NOTE: Not recommended for use on 8 volt systems.
METER: The meter indicates the amount of current measured in
amperes that is being drawn from the charger by a battery. In the
15 Amp charge rate a typical discharged battery may initially draw
more than 15 Amps during the first few minutes of charge. As the
battery continues to charge current should gradually taper to within
6 to 8 amps at full charge.
The START area of the meter is reserved to indicate when a high
rate of current is being drawn from the charger. It is normal for the
meter pointer to be in this area while cranking a vehicle.
When using the 2 amp charge rate the meter may indicate some
activity but doesn’t have the resolution to accurately display the
battery’s state of charge. For this reason you should depend on
the full charge light indicator.
CRANK STARTING:
1. Connect the charger as outlined in the “CHARGING BATTERY
IN VEHICLE” section.
2. For best results charge the battery for 10 minutes before crank-
ing the engine.
3. Set the rotary charge rate selector switch to the 125 Amp start
position that matches the voltage of the vehicle’s battery
4. Crank the engine for 5 seconds, if the engine fails to start, set
the charge rate switch to the 15 Amp rate and charge the bat-
tery for the next 5 to 10 minutes before cranking again.
5. If the engine fails to start after several tries, there maybe a prob-
lem elsewhere with the vehicle.
