STARTER INSPECTIONA6E471418400203MZR-CD (RF Turbo)
On-vehicle Inspection
1. Verify that the battery is fully charged.
•Charge if necessary. (See G–6 BATTERY RECHARGING.)
2. Crank the engine and verify that the starter rotates smoothly without any noise.
•If not as specified, inspect the following:
—Remove the starter, and inspect the magnetic switch and the starter.
—Inspect the related wiring harness and the engine switch.
No Load Test
1. Verify that the battery is fully charged.
•Charge if necessary. (See G–6 BATTERY RECHARGING.)
2. Connect the starter, battery, voltmeter and
ammeter as shown.
3. Operate the starter and verify that it rotates
smoothly.
4. Measure the voltage and current while the starter
is operating.
•If not as specified, replace the starter.
