MX-5 Miata LS L4-1.8L DOHC (2001)
Starter Motor: Testing and Inspection
STARTER INSPECTION
On-vehicle Inspection
1. Verify that the battery is fully charged.
2. Crank the engine and verify that the starter turns smoothly without any noise.
-
Measure the voltage at terminals S and B when the ignition switch is in the START position.
-
If the voltage is within the specification, remove the starter and inspect the magnetic switch and the starter.
-
If the voltage is not as specified, inspect the wiring harness, ignition switch, starter interlock switch (MT), and transmission range switch (AT).
Specification: Above 8 V
No Load Test
1. Verify that the battery is fully charged.
2. Connect the starter, battery, voltmeter, and ammeter as shown.
3. Operate the starter and verify that it turns smoothly.
4. Measure the voltage and current while the starter is operating.
-
If not as specified, repair or replace the inner parts as necessary.
Magnetic Switch Operation Inspection
CAUTION: Applying power for more than 10 seconds can damage the starter. Do not apply power for more than the aforementioned time.
Pull-out test
NOTE: In case the battery is being charged, the pinion may turn while in a protruded state. This is normal because the current flows to the motor
through the pull-in coil and the motor turns.
1. Verify that the drive pinion is pulled out with battery positive voltage connected to terminal S and the starter body grounded.
-
If not pulled out, repair or replace the starter.
