Starter Motor - Positive Circuit Test
NOTE: Always make the multimeter connection at the component terminal rather than at the wiring end of the connector. Making a connection at the wiring end of the connector could result in false readings because the meter will not pick up a high resistance between the wiring connector and component.
1. Make sure the battery is fully charged. REFER to: BATTERY .
2. Perform a battery drain test. REFER to: Battery Drain Check .
3. Connect a remote starter switch between starter solenoid "S" terminal and the battery positive terminal.
4. Connect the multimeter positive lead to the battery positive post. Connect the negative lead to the starter solenoid "M" terminal.
5. Place gear selector lever in Park or Neutral.
6. Engage the remote starter switch. Read and record the voltage. The voltage reading should be 0.5 volt or less.
7. If the voltage reading is 0.5 volt or less, perform Starter Motor - Ground Circuit Test in Component Test(s) .
