OPERATION
TESTING THE BATTERY
1. To help ensure a good connection, clean the 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 lead-
acid battery.
3. Connect the black (negative) cable clamp (B) to the negative terminal (-) on the battery. Twist
the clamps slightly on the post to ensure a good connection.
4. With the clamps connected, the tester’s gauge will show the battery’s current charge. If it is
less than 12V, disconnect the battery and recharge before testing. If recharging will not bring
the reading above 12V, 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.
6. View the meter display (D) and read the battery condition. Refer to the Battery Condition
Analysis table.
7. Release the toggle switch (C) and remove the cable clamps from the battery.
TESTING THE CHARGING SYSTEM
NOTE: The engine should be at normal operating temperature during this test.
1. Connect the positive and negative cable clamps (A & B) to the battery as
previously described.
2. Outside, or in a well-ventilated area, start the vehicle’s engine and run at fast idle speed.
Never start and run the vehicle’s engine in a closed garage.
WARNING! Avoid carbon monoxide poisoning. This gas comes from the vehicle’s exhaust and is
colourless and odourless. It can cause serious injury or death if inhaled. Never run the vehicle’s
engine inside a garage or any other enclosed space.
3. View the meter display (D) and read the charging system condition (far right on the gauge).
Refer to the Battery Condition Analysis table.
CAUTION! Do not press the toggle switch (C) during this test.
