INSPECTION
1. INSPECT STARTER ASSEMBLY
CAUTION: These tests must be performed within 3 to 5 seconds to prevent the coil from burning out.
a. 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 in the illustration. Then check that the clutch pinion gear moves outward.
3. Disconnect the negative (-) lead from terminal C. Check that the pinion gear remains out.
4. Disconnect the negative (-) lead from the starter body. Check that the clutch pinion gear returns inward.
If the result is not as specified, replace the magnet starter switch assembly.
b. Perform operation test without load.
1. Connect the field coil lead wire to terminal C.
Torque: 5.9 N.m (60 kgf.cm, 52 in.lbf)
2. Mount the starter in a vise.
3. Connect the battery and ammeter to the starter as shown in the illustration.
4. Check that the starter rotates smoothly and steadily while the pinion gear is moving outward. Then measure the current.
If the result is not as specified, replace the magnet starter switch assembly.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
