Battery/Starter Load Test (ARBST Test)
- Connect large Red ARBST tester cable to battery positive. Connect large Black ARBST tester cable to battery negative. Place Gray inductive current pick-up around battery positive cable.
- Ensure that 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 Anti-Lock Brake System (ABS) models, 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 displays average amperage drawn by starter during cranking.
- Amperage at 40°-80° F (5°-27° C) should be 80-120 amps, greater than 120° F (50° C) should be 70-110 amps, and less than 40° F (5° C) should be 90-130 amps.
- Tester display will display CRANKING VOLTAGE, which displays average battery voltage during cranking. If voltage is less than 9.5 volts, perform battery load test.
- Tester display will display GOOD STARTER or BAD STARTER. If display reads BAD STARTER, replace starter motor.
