STARTER SYSTEM TEST PROCEDURE a. WIth charger UNPLUGGED, connect the tester clamps to the battery as it is situated in the vehicle: red to the positive(+) terminal, black to the negative (–) terminal. Rock each clamp back and forth to make a good connection. NOTE: The battery must be good and fully charged for this test. b. Only the live voltage will appear on the LED, unless the charger is plugged in, in which case the charge current is displayed and the FAIL LED is lit. The Starter test will be bypassed if attempting to select it, until current is removed. UNPLUG the charger. The PASS/FAIL LEDs will alternate blinking until a crank event is detected. c. Start the vehicle. d. Observe the final cranking voltage that appears on the LED: If the Volts reading is greater than volts, the Starting System is OK. The PASS LED will light.
