ABORTED CHARGE

If charging cannot be completed normally,

charging will abort. When charging aborts,

the charger’s output is shut off and the

CHARGING

(yellow) LED will ash. The

digital display will show an error code

(see the Troubleshooting section for a

description of the error codes). To reset

after an aborted charge, unplug the charger

from the AC outlet, wait a few moments and

then plug it back in.

DESULFATION MODE

Desulfation could take 8 to 10 hours. If

desulfation fails, charging will abort and the

CHARGING

(yellow) LED will ash.

COMPLETION OF CHARGE

Charge completion is indicated by the

CHARGED/MAINTAINING (green) LED.

When pulsing, the charger has switched to

the maintain mode of operation.

MAINTAIN MODE

(FLOAT-MODE MONITORING)

When the CHARGED/MAINTAINING (green)

LED is lit, the charger has started maintain

mode. In this mode, the charger keeps the

battery fully charged by delivering a small

current when necessary. If the charger has to

provide its maximum maintain current for a

continuous 12 hour period, it will go into abort

mode (see Aborted Charge section). This is

usually caused by a drain on the battery or the

battery could be bad.

MAINTAINING A BATTERY

The 28.71326 charges and maintains both 6

and 12 volt batteries.

NOTE: The maintain mode technology

allows you to safely charge and maintain a

healthy battery for extended periods of time.

However, problems with the battery, electrical

problems in the vehicle, improper

connections or other unanticipated conditions

could cause excessive current draws. As

such, occasionally monitoring your battery

and the charging process is required.

USING THE ENGINE START FEATURE

Your battery charger can be used to jump

start your car if the battery is low. Follow all

safety instructions and precautions for

charging your battery. Wear complete eye

protection and protective clothing.

WARNING: Using the ENGINE START

feature WITHOUT a battery installed in the

vehicle will damage the vehicle’s electrical

system.

NOTE: If you have charged the battery and

it still will not start your car, do not use the

Engine Start feature, or it will damage the

vehicle’s electrical system. Have the battery

checked.

1. With the charger unplugged from the

AC outlet, connect the charger to the

battery following the instructions given

in the CHARGING A BATTERY IN THE

VEHICLE section.

2. Plug the charger AC power cord into the

AC outlet.

3. With the charger plugged in and

connected to the battery and chassis,

press the RATE SELECTION button until

the ENGINE START LED is lit.

4. Crank the engine until it starts or 3 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.

5. If the engine fails to start, charge the

battery for 5 more minutes before

attempting to crank the engine again.

6. After the engine starts, unplug the AC

power cord before disconnecting the

battery clamps from the vehicle.

7. 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.

ENGINE STARTING NOTES

During the starting sequence listed above,

the charger is set to one of three states:

• Wait for cranking – While waiting for

cranking, the digital display shows rdy.

The charger waits until the engine is actually

being cranked before delivering the amps for

engine start.

• Cranking – When cranking is detected, the

charger will automatically deliver up to its

maximum output as required by the starting

system for up to 5 seconds. The digital

display shows a countdown of the remaining

crank time.

• Cool Down – After cranking, the charger

enters a mandatory 3 minute (180 second)

cool down state. The digital display indicates

the remaining cool down time in seconds. It

starts at 180 and counts down to 0. After 3

minutes, the digital display will change from

displaying the countdown to displaying rdy.
