Battery/Starter Load Test (ARBST Test)
- Connect ARBST large Red tester cable to battery positive.
Connect ARBST large Black tester cable to battery negative. Place Gray
inductive current pick-up around battery positive cable. Ensure arrow
on Gray inductive pick-up is pointing toward starter motor
solenoid.NOTE: Place Gray inductive current pick-up around battery positive cable between battery positive terminal and starter solenoid connection. Easiest place to connect inductive pick-up is next to brake master cylinder. Battery positive cable runs under master cylinder and is covered by a protective wire conduit. This conduit does not need to be removed for this test. On models equipped with Anti-Lock Brake System (ABS), inductive pick-up can be placed between ABS master cylinder and starter motor.
- Disable ignition system by disconnecting ignition module electrical connector. Press STARTER TEST button on ARBST tester. Position tester so display can be seen from driver's seat.
- When display says CRANK ENGINE, turn ignition to START position. Tester will continue to display CRANK ENGINE for 15 seconds.
- Tester display will display CRANKING AMPS, which shows average amperage drawn by starter during cranking. Amperage should be 80-120 amps at 40-80°F (5-27°C), 70-110 amps at greater than 120°F (50°C), and 90-130 amps at less than 40°F (5°C).
- Tester will display CRANKING VOLTAGE, which shows average battery voltage during cranking. If voltage is less than 9.5 volts, perform battery load test.
- Tester will display GOOD STARTER or BAD STARTER. If display reads BAD STARTER, ensure no engine or flywheel problems and replace starter motor.
