Starters - Except Pickup: Other Mazda 626 GF

MX-5 Miata

1. Disconnect field lead ("M" terminal wire) at solenoid. see scheme 2 Connect positive battery lead to solenoid "S" terminal and negative battery lead to starter body. Starter pinion drive gear should extend outward and stop.
2. Quickly measure pinion gap between end of pinion drive and circlip retainer. (Scheme 8) DO NOT operate starter solenoid for more than 10 seconds. Pinion gap should be.02-.08" (0.5-2.0 mm).
3. If pinion gap is not within specification, adjust by increasing or decreasing thickness of solenoid shims located between solenoid and drive housing.

Scheme 8

STARTER INTERLOCK SWITCH (M/T)

Starter interlock (clutch start) switch is mounted on bracket near top front of clutch pedal. Disconnect interlock switch wiring connector. Using ohmmeter, ensure continuity exists between interlock switch connector terminals when clutch pedal is depressed and no continuity exists when clutch pedal is released. If continuity is not as described, adjust or replace interlock switch.

1. Place armature in growler. Turn on growler and hold a piece of hacksaw blade over armature. Slowly rotate armature. If hacksaw blade is attracted to core or if it vibrates, replace armature.
2. Remove armature from growler. Using an ohmmeter, check continuity between commutator and core. If continuity exists, replace armature.
3. Check continuity between commutator and shaft. If continuity exists, replace armature. Check continuity between each commutator segment. If an open exists between any two segments, replace armature.

1. Clean surface and polish with No. 400 sandpaper if required. If surface is scored, out of round or pitted, turn commutator in a lathe.
2. Maximum commutator runout and minimum diameter of commutator must not exceed specification after turning on lathe.
3. Standard commutator mica undercut depth is .020" (.50 mm). Minimum mica undercut depth is .008" (.20 mm). If undercut is not within specification, undercut to standard depth.

1. Connect one ohmmeter lead to positive brush holder and other lead to negative brush holder. If continuity exists, replace brush holder assembly.
2. Check brush length. Minimum brush length is .28" (7.0 mm). If brush length is less than specified, replace brushes.

OVERRUNNING CLUTCH PINION DRIVE

Hold overrunning clutch housing and turn pinion gear by hand. If pinion turns in both directions or does not turn at all, clutch is faulty. Replace clutch.
