STARTING SYSTEM
GENERAL INFORMATIONM1162000100202
If the ignition switch is turned to the "START"
position, current flows in the pull-in and holding coils
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.

PINION GAP ADJUSTMENT
1. Disconnect the field coil 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 mm5. 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 in order. 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 battery
(+) terminal and starter motor terminal.
3. Connect a voltmeter (15-volt scale) across the
starter motor.
4. Rotate the rheostat to full-resistance position.
5. Connect the battery cable from the battery (-)
terminal to the starter motor body.
6. Adjust the rheostat until the battery voltage shown
on 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:
<4G1> maximum 95 Amps
<4G6> maximum 90 Amps

MAGNETIC SWITCH RETURN TEST1. 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.
