Starters: Other Mitsubishi Galant IX

PINION GAP

1. Disconnect the field coil wire from the "M" terminal of magnetic switch.
2. Connect a 12V battery between "S" terminal and "M" terminal. (Scheme 13)or (Scheme 14).
3. Set switch to ON and pinion will move out.
4. Check the pinion to stopper clearance (pinion gap) with a feeler gauge. (Scheme 15)
5. If the pinion gap is out of specification, adjust by adding or removing gasket(s) between the magnetic switch and front bracket.

STARTER MOTOR DOES NOT OPERATE

1. Check the starter (coil).
2. Check for poor contact at the battery terminals and starter.
3. Check the transmission range switch.

STARTER MOTOR DOES NOT STOP

Check magnetic switch.

1. Is the battery in good condition? If Yes, go to the next step. If No, then charge or replace battery.
2. Disconnect the starter motor "S" (solenoid) terminal connector. Using a jumper wire, apply battery positive voltage to starter motor "S" (solenoid) terminal. Does starter motor operate normally? If Yes, then check ignition switch, transmission range switch and the line between the battery and starter motor "S" (solenoid) terminal. If No, then go to the next step.
3. Check if the cable between starter "B" (battery) terminal and battery positive terminal for connection and continuity. Is the starter cable in good condition? If Yes, then go to the next step. If No, then repair or replace the cable.
4. Check the connection and continuity of the cable between starter motor body and the negative battery terminal. Is the ground line in good condition? If Yes, then go to the next step. If No, then repair or replace cable.
5. Is the starter motor in good condition? If Yes, problem is excessive rotational resistance of the engine. If No, then replace the starter motor.

COMMUTATOR CHECK

1. Place the armature on a pair of V-blocks and check the runout by using a dial gauge. See «STARTER SPECIFICATIONS»(ref-165234-S05500419852004082300000) .
2. Check the outer diameter of the commutator. See «STARTER SPECIFICATIONS»(ref-165234-S05500419852004082300000) .
3. Check the depth of the undercut between segments. See «STARTER SPECIFICATIONS»(ref-165234-S05500419852004082300000) .
4. Replace commutator if runout, diameter or undercut depth is not within specification.

BRUSH CHECK

1. Check the brush for roughness of the surface that contacts the commutator and check the brush length. Replace the brush holder if this measurement exceeds the limit. The minimum limit is .28" (7.0 mm).
2. In the case contacting surface has been corrected or the brush has been replaced, correct the contacting surface winding sandpaper around the commutator.

OVERRUNNING CLUTCH

1. While holding clutch housing, rotate the pinion. Drive pinion should rotate smoothly in one direction, but should not rotate in opposite direction. (Scheme 16) If clutch does not function properly, replace overrunning clutch assembly.
2. Inspect the pinion for wear or burrs. If pinion is worn or burred, replace the overrunning clutch assembly. If pinion is damaged, also inspect the ring gear for wear or burrs.

Scheme 16

FRONT & REAR BRACKET BUSHING CHECK

Inspect the bushing for wear or burrs. If the bushing is worn or burred, replace the front bracket assembly or rear bracket assembly.

ARMATURE CHECK

1. Check that the armature coil is not grounded.
2. Place armature in a growler. (Scheme 17)
3. Hold a thin steel blade parallel and just above while rotating the armature slowly in the growler. A shorted armature will cause a blade to vibrate and attracted to the core. Replace the shorted armature.
4. Check the insulation between the armature coil cores and the commutator segments. They are normal if there is no continuity. (Scheme 18)
5. Check for continuity between the segments. The condition is normal if there is continuity. (Scheme 19)

Cleaning

Overrunning clutch is pre-lubricated at the factory and solvent will wash lubrication from clutch. The drive unit may be cleaned with a brush moistened with cleaning solvent and wiped dry with a cloth.
