Mitsubishi Outlander: Starting System

GENERAL INFORMATION

If the ignition switch is turned to the "START" position, current flows in the coil provided inside magnetic switch, attracting the plunger. When the plunger is attracted, the lever connected to the plunger is actuated to engage the starter clutch.

On the other hand, attracting the plunger will turn on the magnetic switch, allowing the "B" terminal and "M" terminal to conduct. Thus, current flows to engage the starter motor.

When the ignition switch is returned to the "ON" position after starting the engine, the starter clutch is disengaged from the ring gear.

An overrunning clutch is provided between the pinion and the armature shaft, to prevent damage to the starter.

OPERATION

For models equipped with A/T, when the ignition switch is turned to the "ST" position while the selector lever is at the "P" or "N" position, the contact (magnetic switch) of the starter is switched ON and the starter motor is activated.

INSPECTION

PINION GAP ADJUSTMENT

1. Disconnect the lead wire from the M-terminal of the magnetic switch.

2. Connect a 12-volt battery between the S-terminal and M-terminal.

CAUTION

This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.

3. Set the switch to "ON", and the pinion will move out.

4. Check the pinion-to-stopper clearance (pinion gap) with a feeler gauge.

Standard value: 0.5 − 2.0 mm (0.02 − 0.07 inch)

Mitsubishi Outlander. Engine Electrical

5. If the pinion gap is out of specification, adjust by adding or removing gasket(s) between the magnetic switch and front bracket.

MAGNETIC SWITCH PULL-IN TEST

1. Disconnect the field coil wire from the M-terminal of the magnetic switch.

CAUTION

This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.

2. Connect a 12-volt battery between the S-terminal and M-terminal.

3. If the pinion moves out, the pull-in coil is good. If it doesn't, replace the magnetic switch.

MAGNETIC SWITCH HOLD-IN TEST

1. Disconnect the field coil wire from the M-terminal of the magnetic switch.

CAUTION

This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.

2. Connect a 12-volt battery between the S-terminal and body.

3. Manually pull out the pinion as far as the pinion stopper position.

4. If the pinion remains out, everything is operating properly. If the pinion moves in, the hold-in circuit is open. Replace the magnetic switch.

FREE RUNNING TEST

1. Place the starter motor in a vise equipped with soft jaws and connect a fully-charged 12-volt battery to the starter motor as follows:

2. Connect a test ammeter (100-ampere scale) and carbon pile rheostat in series between the positive battery terminal and starter motor terminal.

3. Connect a voltmeter (15-volt scale) across the starter motor.

4. Rotate carbon pile to full-resistance position.

5. Connect the battery cable from the negative battery terminal to the starter motor body.

6. Adjust the rheostat until the battery positive voltage shown by the voltmeter is 11 V.

7. Confirm that the maximum amperage is within the specifications and that the starter motor turns smoothly and freely.

Current: maximum 90 Amps

MAGNETIC SWITCH RETURN TEST

1. Disconnect the field coil wire from the M-terminal of the magnetic switch.

CAUTION

This test must be performed quickly (in less than 10 seconds) to prevent the coil from burning.

2. Connect a 12-volt battery between the M-terminal and body.

WARNING

Be careful not to get your fingers caught when pulling out the pinion.

3. Pull the pinion out and release. If the pinion quickly returns to its original position, everything is operating properly. If it doesn't, replace the magnetic switch.

STARTER MOTOR PARTS CLEANING

1. Never clean in a solvent such starter motor parts as the magnetic switch, brush holder, and armature. If they are soaked in a solvent, their insulation could be impaired.

When these parts require cleaning, wipe off contamination with cloth.

2. Never soak the drive unit in a solvent. If it is washed in a solvent, the grease having been packed in the overrunning clutch at the factory will be washed out. Wipe the drive unit with cloth if it requires cleaning.

OVERRUNNING CLUTCH

1. Make sure that the pinion cannot be turned counterclockwise and can be turned clockwise freely.

2. Check the pinion for abnormal ware and damage.

Mitsubishi Outlander. Engine Electrical

BRUSHES

1. Check the commutator contacting surface of each brush for abnormal roughness. Also check the height of the brush.

Replace the brush holder if the height is lower than the limit.

Limit: 7.0 mm (0.28 inch)

2. When the contact surface of the brush is rectified or the brush holder is replaced, recondition the contact surface with sandpaper wrapped around the commutator.

ARMATURE COIL

1. Check the armature coil for short circuit as follows.

2. Set the armature in a growler.

CAUTION

Clean the surface of the armature thoroughly before performing the test.

3. While holding a thin strip of iron against the armature in parallel with its axis, turn the armature slowly. The armature is normal if the iron strip is not attracted to the armature or it does not vibrate.

Mitsubishi Outlander. Engine Electrical

4. Check the insulation between commutator segments and armature coils. The armature coils are properly insulated if no continuity is present.
