GENERAL INFORMATIONM1162000100202
If the ignition switch is turned to the "START" posi-
tion, current flows in the pull-in and holding coils pro-
vided 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" posi-
tion after starting the engine, the starter clutch is dis-
engaged from the ring gear.
An overrunning clutch is provided between the pinion
and the armature shaft, to prevent damage to the
starter.

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.

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.

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.

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 c able 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

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 it s axis, turn the armature
slowly. The armature is normal if the iron strip is
not attracted to the armature or it does not vibrate.
