2. With the charger unplugged from the A.C. outlet, connect the charger to
the battery following the instructions given in Section 6 (FOLLOW THESE
STEPS WHEN THE BATTERY IS INSTALLED IN A VEHICLE).
3. Plug the charger A.C. power cord into the A.C. outlet, and then move the
timer switch from OFF to the HOLD position.
4.
With the charger plugged in and connected to the battery of the vehicle, set
the charge rate selector switch to the engine start position.
5. Crank the engine until it starts or 5 seconds pass. If the engine does not
start, wait 3 minutes before cranking again. This allows the charger and
battery to cool down.
NOTE: During extremely cold weather, or if the battery is under 2 volts, charge
the battery for 5 minutes before cranking the engine.
6. If the engine fails to start, charge the battery for 5 more minutes before
attempting to crank the engine again.
7. After the engine starts, move the charge rate selector switch and timer to
the off position and unplug the A.C. power cord before disconnecting the
battery clips from the vehicle.
8. Clean and store the charger in a dry location.
NOTE: If the engine does turn over but never starts, there is not a problem
with the starting system; there is a problem somewhere else with the vehicle.
STOP cranking the engine until the other problem has been diagnosed and
corrected.
Using the Battery Voltage Tester (Models SE-2254 and SE-4022 only)
1.
Set the Voltage Selector switch to the correct setting (6V or 12V) to match
the battery to be tested.
2. Set the timer to the OFF position.
3. Connect the battery to the charger as specified in sections 6 and 7. The
charger does not need to be plugged into an A.C. outlet.
4. Read the voltmeter.
Keep in mind that this reading is only a battery voltage reading, a false charge
may mislead you. We suggest that you turn on the headlights for a couple
of minutes and then wait a couple of minutes after you have turned them off
before reading the meter. Then, follow the convenient color code shown on the
meter.
Using the Battery Load Tester (Model SE-8050 only)
1. Set the Voltage Selector switch to the correct setting (6V or 12V) to match
the battery to be tested.
2. Set the timer to the OFF position.
3. Connect the battery to the charger as specified in sections 6 and 7. The
charger does not need to be plugged into an A.C. outlet.
4. Press the Battery Load Test switch to LOAD ON for 10 seconds and read
the voltmeter.
Green – Indicates the battery capacity is OK. The battery may or may not be
fully charged. Check the specific gravity to determine the state of charge. If the
specific gravity shows less than a full charge, check for an electrical drain on
the battery or for possible charging system problems. Recharge the battery to
full charge.
Yellow or Red but the needle remains steady – Indicates that the battery
capacity is not satisfactory. The battery may be either defective or not fully
charged. Check the specific gravity of the battery to see which condition exists.
If charging does not bring the battery up to a full charge, the battery should be
replaced.
