Engine Start
1. Set the charge rate and timer to the off positions.
2. With the Charger unplugged from the AC outlet, connect the Charger to the battery.
3. Plug the Charger AC power cord into the AC outlet, then move OFF to HOLD position.
4. Set the charge rate to the engine start position that matches the vehicle battery, and then
crank the engine. Follow the duty cycle printed on the front panel of your charger for
proper ON/OFF times. During extremely cold weather, or when the battery is severely
exhausted, charge the battery for about five minutes before attempting to crank the en-
gine.
5. If the engine fails to start, charge the batter y for five more minutes before cranking the
engine.
6. After the engine starts, move the charge rate switch to OFF and unplug the AC power
cord from the outlet before disconnecting the DC cable clamps.
require 1 to 1-1/2 hours of charging at the 40 amp rate to reach the full charge state. For the
same battery with its timer set to maximum, 3 hours overcharging will occur. Slight overcharging
will not likely harm a battery that was otherwise in good condition. When the state of charge
is unknown, start out with a timer setting of one hour or less.
Hold: This position defeats the timer function, allowing for continuous operation. Use it when
you want to charge more than 3 hours. This is normally used when the 2 amp charge rate
is selected. Be sure to monitor the charging and stop the charge when the battery is fully
charged.
Rotary Switch: Use the rotary switch to select the charge rate or engine start setting your
require. Read the switch dial for the appropriate setting.
Ammeter: The ammeter indicates the amount of current measured in amperes that’s drawn
from the battery. For example, in the 40 amp charge rate a typical discharged battery will ini-
tially draw approximately 40 amps. As the battery continues to charge, current will taper to 15
to 20 amps at full charge. When cranking an engine, the starter motor draws upward to 200
amps. The meter needle will be at the extreme right side. The 2 amp charge rate may indicate
some activity on the meter. The meter doesn’t have the resolution to display this low rate.
Operation (continued)Troubleshooting
Symptom: Ammeter display reads maximum.
Probable Cause: Defective battery.
Remedy: Check or replace battery.
Symptom: No ammeter reading.
Probable Cause: 1. No power to charge. 2. Battery cables not making connection.
3. Two amp charge rate being used.
Remedy: 1. Check power and cable outlet connections. 2. Clean battery cables and reset
cable clamps. 3. None, meter will not indicate here.
Symptom: Charging current not to full output.
Probable Cause: 1. Battery is partially charged. 2. Defective battery, will not hold full
charge.
Remedy: 1. Continue charging. 2. Check and/or replace battery.
