Hold-In Windings Test

  1. If solenoid is not removed from starter motor assembly, disconnect field lead from terminal "M" on solenoid and insulate field lead from solenoid motor terminal. Connect an ammeter and switch in series with 12-volt battery and starter solenoid terminal "S" as illustrated. See Figure. Connect a voltmeter between solenoid terminal "S" and ground. Connect a carbon pile across battery.
  2. Turn switch on and quickly adjust carbon pile load until voltage reads as specified. See PULL-IN WINDINGS SPECIFICATIONS table. Check ammeter reading. Turn off carbon pile and open switch. If amperage reading is not 10-20 amps, replace starter solenoid.
