PINION GAP ADJUSTMENT
)
)
- Disconnect the field coil wire from the M-terminal of the magnetic switch.
- Connect a 12-volt battery between the S-terminal and M-terminal.
- Set the switch to "ON", and the pinion will move out.
CAUTION)
- Check the pinion-to-stopper clearance (pinion gap) with a feeler gauge.
Standard value: 0.5 -
2.0 mm
)
- 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
)
)
- Disconnect the field coil wire from the M-terminal of the magnetic switch.
- Connect a 12-volt battery between the S-terminal and M-terminal.
CAUTION- If the pinion moves out, the pull-in coil is good. If it doesn't, replace the magnetic switch.
MAGNETIC SWITCH HOLD-IN TEST
)
)
- Disconnect the field coil wire from the M-terminal of the magnetic switch.
- Connect a 12-volt battery between the S-terminal and body.
CAUTION- Manually pull out the pinion as far as the pinion stopper position.
- 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
)
)
- 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:
- Connect a test ammeter (100-ampere scale) and carbon pile rheostat in series between the positive battery terminal and starter motor terminal.
- Connect a voltmeter (15-volt scale) across the starter motor.
- Rotate the rheostat to full-resistance position.
- Connect the battery cable from the negative battery terminal to the starter motor body.
- Adjust the rheostat until the battery positive voltage shown on the voltmeter is 11 V.
- 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
)
)
- Disconnect the field coil wire from the M-terminal of the magnetic switch.
- Connect a 12-volt battery between the M-terminal and body.
CAUTION- 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.
