The following information contains troubleshooting and replacement procedures for the intermediate transmission type starter/solenoid. To determine if the starter or solenoid should be replaced, proceed as follows:
Be sure battery is fully charged and that battery voltage can be read at terminal 30 of the starter.
Important: Place transmission selector lever in park or neutral.
With a suitable jumper, bridge terminal 30 and terminal 50. Do not allow connections to touch chassis ground. If the starter runs, check the ignition/starter switch and terminal 50 path. Repair as necessary.
If the starter does not run, remove the jumper from terminal 30 to terminal 50 and install from terminal 30 to terminal B. Do not allow connections to touch chassis ground. If the starter motor runs, replace the solenoid. If the motor does not run, replace the entire starter. If the solenoid is to be replaced, proceed as follows:
