October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
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.
