Starter Motor Test

If starting your vehicle is difficult, you may have unnecessary starter motor draw, which dramatically shortens battery life. This test identifies starter motor performance.

1.Make sure your engine is running at normal operating temperature, and that the battery is fully charged and in good condition.

2.Connect the Red Clamp (+) to the positive (+) terminal post on the battery. Connect the Black Clamp (-) to the negative (-) terminal post on the battery.

3.Turn the Load Knob (C) counterclockwise to the Off position.

4.Disable the engine to make sure the car will not start. Refer to your vehicle’s service / technical manual.

5.While watching the DC Volt scale (see page 6), crank the engine briefly to determine the voltage reading during cranking.

A display reading of 9 volts or less indicates excessive current draw. This may be caused by a bad connection of a failing starter motor, or, the battery is too small for the vehicle’s requirements. Consult a qualified mechanic.

6.When starter motor test is complete, remove Black Clamp (-) from battery first; then remove Red (+) clamp.

INSPECTION, MAINTENANCE, AND CLEANING

1.Periodically check all nuts, bolts, and screws for tightness.

2.Store in a clean, dry location.

3.Clean the outside of the unit with a damp cloth. Never use solvents to clean any parts of this tool. Use compressed air to blow out debris from the load vents. Allow tool to dry completely before use.

4.After each use, clean the Cable Clamps of any possible battery electrolyte. Apply a thin coat of silicon grease to prevent corrosion.
