Starter Test

Important

Place the gray inductive current pick-up around the battery positive cable between the battery positive terminal and the starter motor solenoid connection. The easier place to connect the inductive pick-up is in front of the brake master cylinder. The battery positive is covered by a protective wire conduit. This conduit does not need to be removed from this test.

1. Press the STARTER TEST button on the system tester. The tester will display:
2. "INPUT # CYLS." Input the number of cylinders.
3. Disable the ignition system by disconnecting the electrical connection at the ignition module.
4. Position the tester so the display can be seen from the driver's seat. When the display says CRANK ENGINE, turn the ignition to the START position. The tester will continue to display CRANK ENGINE for 15 seconds.




5. The display on the system tester will display the following information:

Cranking Amps

This displays the average amperage drawn by the starter motor during cranking. The following amperage readings are general guidelines for normal operation:

Important

As the ambient temperature decreases, the amperage required to crank the engine increases.

Cranking Voltage

This displays the average battery voltage during cranking. If the voltage is below 9.5 volts, perform the BATTERY TEST to make sure the battery is charged (green eye) and good.

Good cranking voltage and a slow starter cranking speed can be caused by loose or corroded cables.

Notice

The starter should not be engaged for more than 15 seconds at a time. If the vehicle does not start after 15 seconds, turn the ignition key to the Off position for 20 seconds before attempting to restart the vehicle.

Good Starter/Bad Starter

If the display reads BAD STARTER, replace the starter motor only after determining that there is no engine mechanical problems or flywheel binding problems.
