INSPECTION
1. INSPECT STARTER ASSY
NOTICE:
These tests must be performed within 3 to 5 seconds to
avoid burning out the coil.
(a) Do pull±in test
(1) Disconnect the field coil lead wire from terminal C.
(2) Connect the battery to the magnetic switch as
shown in the illustration on the left. Check that the
clutch pinion gear is extended.
If the clutch pinion gear is not extended, replace the magnetic
switch.
(b) Do hold±in test
(1) Disconnect the negative (±) lead from the terminal
C with the above condition (a) is being maintained.
Check that the pinion gear remains extended.
If the clutch pinion gear returns, replace the magnetic switch.
(c) Inspect clutch pinion gear return
(1) Disconnect the negative (±) lead from the switch
body. Check that the clutch pinion gear returns.
If the clutch pinion gear does not return, replace the magnetic
switch.
