Sears Official Manual for 12 Volt Battery Charger

VOLTMETER:

Foran accurate reading of your battery'svoltage before you begin charging it, use the voltmeter as follows:

1.Set the timer to the OFF position, turn the voltage selector switch to 12 or 6 volt, according to the battery you are testing, and then connect the charger as indicated in the "Charging your battery in the vehicle" section on page 9. The charger does not have to be plugged into an outlet.

2.If a battery has recently been charged or in a vehicle that has recently been operated, you may want to turn your headlights on for a few minutes before you read the meter to avoid a false reading from a surface charge. Then turn off the lights, read the meter, and follow the convenient color coding.

2.Set the BATTERY TEST switch to 12 or 6 volts, according to the battery you are testing.

3.Set timer switch to the OFF position.

4.With the charger properly connected to the battery and chassis, start the engine. Read the battery test meter with the engine at a fast idle. The battery

should be in a good state of charge before doing the test.

5.The voltmeter is divided into three color zones:

A.Green and Ughter Green --Charging system is good.

B.Yellow --Vehicle charging system output is low.

C. Red --Vehicle charging system is bad.

NOTE: If meter needle reads in the Red or Yellow, the charging system may have a loose belt, a faulty voltage regulator, or a worn-out alternator/generator. Additional tests may be required to find the exact cause. Take the vehicle to a qualified service center.
