G. OPERATING INSTRUCTIONS:
ENGINE START
1. Connect the battery charger to the vehicle according to
section E (CHARGING BATTERY IN VEHICLE) found earlier
in this manual.
2. Performance will be enhanced if you charge the battery for
5-10 minutes in the 12v 15 amp position before attempting
to start.
3. Set the charge rate selector switch to the 110 amp start
position.
4. Crank the engine for 2-4 seconds.
5. If the engine fails to start, charge the battery in the 12v 15
amp position for another 5-15 minutes and then attempt to
start the engine again.
6. If the engine fails to start after several attempts, there may
be a problem elsewhere with the vehicle.
7. When disconnecting, always disconnect power cord first,
then remove clip from vehicle chassis, and finally remove
the clip from the battery terminal.

The approximate time required to bring a battery to a full charge
state depends upon the number of ampere hours (AH’s) de-
pleted from the battery. AH’s are determined by multiplying the
number of hours times the number of amps supplied by a bat-
tery to a load. For example - if a load was connected to a battery
which drew 10 Amps for a period of 5 hours, the battery will
have supplied 50 AH’s. The approximate recharge time required
to restore the 50 AH’s depleted from the battery would be calcu-
lated by dividing 50 AH’s by the selected charge rate. If the 15
Amp charge rate is chosen then divide 50 AH’s by 15 Amps, this
equal to 3.3 hours or 3 hour and 20 minutes. During the charge
cycle, the 15 Amp charge rate will not remain constant, rather
as the battery charges it will taper to approximately 6-7 Amps.
Also not all of the energy going into the battery is directly con-
verted, some is lost in the form of heat. For these reasons allow
an additional 25% in charge time. For this example add 50 min-
utes to the 3 hour and 20 minutes for a total recharge time of 4
hour and 10 minutes.
