Set the charge rate switch and the timer to the OFF position.1.
With the charger unplugged from the AC outlet, connect the charger to the battery 2.
following the instructions given in Section 6 (FOLLOW THESE STEPS WHEN THE
BATTERY IS INSTALLED IN A VEHICLE).
Plug the charger AC power cord into the AC outlet, and then move the timer switch 3.
from OFF to the HOLD position.
With the charger plugged in and connected to the battery of the vehicle, set the 4.
charge rate selector switch to the engine start position.
Crank the engine until it starts or 3 seconds pass. If the engine does not start, wait 3 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.
If the engine fails to start, charge the battery for 5 more minutes before attempting to 6.
crank the engine again.
After the engine starts, move the charge rate selector switch to the OFF position and 7.
unplug the AC power cord before disconnecting the battery clips from the vehicle.
Clean and store the charger in a dry location.8.
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 four basic steps required to test the battery state of charge:
With the charger unplugged from the AC outlet, connect the charger to the battery 1.
following the instructions given in Sections 6 and 7.
Set the charge rate switch and the timer to the OFF position.2.
Plug the charger AC power cord into the AC outlet, following the instructions given in 3.
Section 8.
Read the voltage on the voltmeter.4.
Using the Alternator Performance Tester
Overview
This battery charger has a built-in alternator tester that displays an estimate of the
alternator’s relative output compared to normal alternators. The alternator % values
displayed should be taken as a general reference, not a precise diagnosis. The
alternator tester functions the same as the built-in battery voltage tester (see previous
section for details) with a few differences.
Testing Sequence: There are four basic steps required to operate this unit as an
alternator tester:
With the charger unplugged from the AC outlet, connect the charger to the battery 1.
following the instructions given in Sections 6 and 7.
Set the charge rate switch and the timer to the OFF position.2.
Plug the charger AC power cord into the AC outlet, following the instructions given in 3.
Section 8.
Start the vehicle and turn on the vehicle’s headlights. Read the voltage on the voltmeter.4.
