Starting System: Inspection

INSPECT STARTER ASSY
NOTE: These tests must be performed within 3 to 5 seconds to prevent the coil from burning out.
1. Perform pull-in/ holding test
  1. Disconnect the field coil lead wire from terminal C.
  2. Connect the battery to the magnetic switch as shown. Then check that the clutch pinion gear moves outward.
