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 4 seconds pass. If the engine does not
start, wait 5 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 timer switch to the OFF position and
unplug the AC 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
Overview
This battery charger has a built-in voltmeter to test your battery's state of
charge. The charger does not have a built in load tester. As such, a recently
charged battery could have a temporarily high voltage due to what is known as
"surface charge". The voltage of such a battery will gradually drop during the
period immediately after the charging system is disengaged. Consequently, the
tester could display inconsistent values for such a battery. For a more accurate
reading, the surface charge should be removed by temporarily creating a load
on the battery, such as by turning on lights or other accessories for a couple
of minutes before you read the display. Read it a couple of minutes after you
have shut the headlights off.
Testing Sequence: There are two basic steps required to test the battery state
of charge:
1.
With the charger unplugged from the AC outlet, connect the charger to the
battery following the instructions given in Sections 6 and 7.
2.
Read the voltage on the voltmeter and compare it to the chart shown
below.
6 Volt Battery
Voltage Reading
6.4 or More
6.1 to 6.3
Less than 6.1
General Charging Notes
Fan: The charger is designed to control its cooling fan for efficient operation.
Consequentially, it is normal for the fan to start and stop when maintaining a
fully charged battery. The fan does not run in Tester Mode. Keep the area near
the charger clear of obstructions to allow the fan to operate efficiently.
Voltage: The voltage displayed during charging is the charging voltage and is
usually higher than the battery's resting voltage.
12 Volt Battery
Voltage Reading
12.8 or More
12.2 to 12.7
