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 battery to the magnetic switch as shown. Check that the pinion gear moves outward.
If the pinion gear does not move, replace the magnetic switch.
2. PERFORM HOLD-IN TEST
While connected as above with the pinion gear out, disconnect the negative (-) lead from terminal C. Check that the pinion gear remains out.
If the pinion gear returns inward, replace the magnetic switch.
3. INSPECT PLUNGER RETURN
Disconnect the negative (+) lead from the switch body. Check that the pinion gear returns inward.
If the pinion gear does not return, replace the magnetic switch.
4. PERFORM NO-LOAD PERFORMANCE TEST
(a) Connect battery and ammeter to the starter as shown.
(b) Check that the starter rotates smoothly and steadily with the pinion gear moving out. Check the reading on the ammeter.
Standard amperage: 90 A or less at 11.5 V
