NOTICE:
These tests must be done within 3 to 5 seconds to avoid
burning out the coil.
1. DO 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.
2. DO HOLD−IN TEST
With battery connected as above with the clutch pinion gear
out, disconnect the negative (−) lead from terminal C. Check
that the pinion gear remains out.
3. INSPECT CLUTCH PINION GEAR RETURN
Disconnect the negative (−) lead from the switch body.
Check that the clutch pinion gear returns inward.
4. DO 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
reads the specified current.
Specified current:
1.2 kW, 1.4 kW type
90 A or less at 11.5 V
1.8 kW, 2.0 kW type
