GR8 ELECTRICAL SYSTEM TESTER
The Midtronics GR8 battery system tester is designed to help diagnose the cause of a defective battery. for directions on using the Midtronics GR8 battery tester. Refer to BATTERY, STANDARD PROCEDURE .
STARTER SOLENOID
| WARNING | Check to ensure that the transmission is in the park position with the parking brake applied. This may result in personal injury or death. |
- Verify battery condition. Battery must be in good condition with a full charge before performing any starter tests. Refer to «BATTERY - DIAGNOSIS AND TESTING»(ref-646227-S31898064892014072800000) .
- Perform Starter Solenoid test BEFORE performing the starter relay test.
- Perform a visual inspection of the starter/starter solenoid for corrosion, loose connections or faulty wiring.
- Locate and remove the starter relay.
- Connect a remote starter switch or a jumper wire between the remote battery positive post and terminal 87 of the starter relay connector. If engine cranks, starter/starter solenoid is good. Go to the Starter «RELAY TEST»(ref-646337-S18471276792014072800000) . If engine does not crank or solenoid chatters, check wiring and connectors from starter relay to starter solenoid and from the battery positive terminal to starter post for loose or corroded connections. Particularly at starter terminals. Repeat test. If engine still fails to crank properly, trouble is within starter or starter mounted solenoid, and replace starter. Inspect the ring gear teeth.
STARTER RELAY
| WARNING | Check to ensure that the transmission is in the park/neutral position with the parking brake applied. This may result in personal injury or death. |
SAFETY SWITCHES
For diagnostics of the Transmission Range Sensor. Refer to the appropriate Transmission Service Information for more information.
If equipped with Clutch Interlock/Upstop Switch. Refer to DIAGNOSIS AND TESTING .
IGNITION SWITCH
After testing starter solenoid and relay, test ignition switch and wiring. Refer to the IGNITION SYSTEM - SERVICE INFORMATION - 1.4L or IGNITION SYSTEM - SERVICE INFORMATION - 2.0L & 2.4L and SYSTEM WIRING DIAGRAMS article for more information. Check all wiring for opens or shorts, and all connectors for being loose or corroded.
