Starters - Evolution Mitsubishi Lancer Evolution VIII

DESCRIPTION & OPERATION

If the ignition switch is turned to START position, current flows in the coil provided inside magnetic switch, attracting the plunger. When plunger is attracted, the lever connected to plunger is actuated to engage starter clutch. On the other hand, attracting plunger will turn on magnetic switch, allowing "B" terminal and "M" terminal to conduct. Thus, current flows to engage starter motor. When ignition switch is returned to ON position after starting engine, starter clutch is disengaged from ring gear.

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

The interlock switch contact is switched OFF when clutch pedal is depressed. When ignition switch is switch to START position, electricity flows to starter relay and starter motor, contact (magnetic switch) of the starter is switched ON and starter motor is activated.

Note. If the ignition switch is switched to START position without clutch pedal being depressed, electricity flows to starter relay (coil), clutch pedal position switch (contacts) and to ground, with result that contacts of starter relay are switched OFF and because power to starter motor is thereby interrupted, starter motor will not operate.

PINION GAP

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

TROUBLE SHOOTING

STARTER MOTOR DOES NOT OPERATE

1. Check the starter (coil).
2. Check for poor connection at the battery terminals and starter.
3. Check starter relay.
4. Check the interlock switch.

STARTER MOTOR DOES NOT STOP

Check the magnetic switch.

ON-VEHICLE TESTING

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, starter relay, interlock 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.

STARTER RELAY CHECK

For starter relay testing (Scheme 3)

Scheme 3

MAGNETIC SWITCH PULL-IN TEST

1. Disconnect field coil wire from "M" terminal of the magnetic switch. (Scheme 4)
2. Connect a 12-volt battery between "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.

Scheme 4

MAGNETIC SWITCH HOLD IN TEST

1. Disconnect the field coil wire from "M" terminal of the magnetic switch. (Scheme 5)
2. Connect 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 pinion moves in, hold-in circuit is open. Replace the magnetic switch.

Scheme 5

MAGNETIC SWITCH RETURN TEST

1. Disconnect the field coil wire from the "M" terminal of the magnetic switch. (Scheme 6)
2. Connect a 12-volt battery between the "M" terminal and body.
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.

Scheme 6

FREE RUNNING TEST

1. Place the starter motor in a vise equipped with soft jaws and connect a fully-charged 12-volt battery to starter motor.
2. Connect a test ammeter (100-ampere scale) and carbon pile rheostat in series between the positive battery terminal and starter motor terminal. (Scheme 7)
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 11V.
7. Confirm that the maximum amperage is 95 amps, and that the starter motor turns smoothly and freely.
