Starter Inspection

Ensure battery is fully charged, battery cables and terminals are clean and tight, and engine grounds are okay. Turn the ignition switch to START and verify that the starter turns smoothly with normal operating sound while cranking. If the starter does not operate, measure voltage at starter "S" and "B" using a voltmeter. If voltage is greater than 8 volts and vehicle does not crank, repair or replace starter as required. Remove the starter and inspect the magnetic switch and starter harness. If not, inspect the wiring harness, ignition switch, starter interlock switch on manual transmission vehicles, and transmission range sensor on automatic transmission vehicles.
