Solenoid Pull-In Coil Test

NOTE: Perform the following solenoid tests with starter assembled and field lead disconnected from starter at solenoid.
CAUTION: DO NOT  engage starter solenoid for longer than 5 seconds during testing or damage to coil winding may result.
  1. Disconnect field lead from solenoid field lead (solenoid-to-starter wire) terminal. See Fig 1 . Ensure field lead does not touch starter housing. Connect negative lead of 12-volt battery to solenoid field lead terminal (terminal "C"). See Fig 1 or 6.
  2. Connect another negative battery lead to starter drive housing. Connect positive battery lead to solenoid ST terminal. See Fig 1 .
  3. Pinion gear should extend quickly and completely when solenoid is energized. If pinion gear does not operate as indicated, replace solenoid.
