OPERATING INSTRUCTIONS
Testing the Battery
CAUTION! Undercharged
NEVER TEST OR CHARGE A FROZEN BATTERY.
1.To help ensure a good connection, clean battery terminals with a solution of baking soda and water, and wipe the battery terminals with a cloth to remove any dirt and grease.
2.Connect the red (positive) Cable Clamp (A) to the positive terminal (+) on the 6 or 12 V
3.Connect the black (negative) Cable Clamp (B) to the negative terminal
4.With the clamps connected, the tester’s gauge will show the battery’s current charge. If it is less than 12 V, disconnect the battery and recharge before testing. If recharging will not bring the reading above 12 V the battery is defective. If it shows no reading, verify that the tester is connected properly. If the tester is connected properly, the battery is defective.
5.Press (and hold) the Toggle Switch (C) for at least 5 seconds to simulate an actual load on the battery.
