Testing the Battery

1. Wipe the battery terminals with a cloth to remove any dirt and grease.

2. Make sure the Load Knob (C) is in the off position. Connect the red (positive) Cable

Clamp (A) to the positive terminal (+) on the 12V battery.

3. Connect the black (negative) Cable Clamp (B) to the negative terminal (–) on the

battery.

4. Turn the Load Knob (C) clockwise until the DC ammeter reads 1/2 the Cold Crank Amp

(CCA) rating or three times the amp hour (Ah) capacity of the battery. The CCA and Ah

rating are printed on the battery label.

Maintain load for 15 seconds to simulate an actual load on the battery. After 15

seconds have passed, the unit will sound with a beep.

5. View the DC Volts Meter and read the battery condition. Refer to the “Battery Condition

Analysis” section on the next page.

6. Turn the Load Knob (C) counterclockwise to Off, and remove the Cable Clamps from

the battery.

Note: Freezing temperatures affect the battery test reading. Decrease the battery

rating 50 cold cranking amps for each 50°F (10°C) below freezing 30°F (0°C).

Testing the Charging System
