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

MAGNETIC SWITCH PULL-IN TEST

(1) Disconnect field coil wire from M-terminal of magnetic
switch.
(2) Connect a 12 V battery between S-terminal and M-terminal.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.
(3) If pinion moves out, then pull-in coil is good. If it doesn't,
replace magnetic switch.

MAGNETIC SWITCH HOLD-IN TEST

(1) Disconnect field coil wire from M-terminal of magnetic
switch.
(2) Connect a 12 V battery between S-terminal and body.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.
(3) Pull out the pinion by hand until it comes into contact
with the pinion stopper.
(4) If pinion remains out, everything is in order. If pinion moves
in, hold-in circuit is open. Replace magnetic switch.
FREE RUNNING TEST
(1) Place starter motor in a vise equipped with soft jaws and
connect a fully-charged 12-volt battery to starter motor
as follows:
(2) Connect a test ammeter (loo-ampere scale) and carbon
pile rheostat in series with battery positive post and starter
motor terminal.
(3) Connect a voltmeter (15volt scale) across starter motor.
(4) Rotate carbon pile to full-resistance position.

(5) Connect battery cable from battery negative post to starter
motor body.
(6) Adjust rheostat until the battery voltage shown by the
voltmeter is 11 V.
(7) Confirm that the maximum amperage is within the specifi-
cations and that the starter motor turns smoothly and freely.
Current: Max. 90 Amps
