PERFORMANCE TEST OF STARTER
NOTICE: These tests must be performed within 3 to 5
seconds to avoid burning out the coil.
1. PERFORM PULL-IN TEST
(a) Disconnect the field coil lead wire from terminal C.
(b) Connect the battery to the magnetic switch as shown.
Check that the clutch pinion gear moves outward.

While connected as above with the clutch pinion gear out,
disconnect the negative (-) lead from terminal C. Check
that the pinion gear remains out.

netic switch assembly.
3. INSPECT CLUTCH PINION GEAR RETURN
Disconnect the negative (-) lead from the switch body.
Check that the clutch pinion gear returns inward.
If the clutch pinion gear does not return, replace the
magnetic switch assembly.
4. PERFORM NO-LOAD PERFORMANCE TEST
(a) Connect the battery and ammeter to the starter as
shown.
(b) Check that the starter rotates smoothly and steadily
with the pinion gear moving out. Check that the
ammeter shows the specified current.
Specified current:
12 V type 180 A or less at 11 V
