1ELll:
Field coil wire
6ELOO!
Carbon-pile rheostat
(5)
If
pinion gap is out of specification, adjust
by adding or
removing gaskets between magnetic switch atid front
bracket.
PULL-IN TEST OF MAGNETIC SWITCH
(1) Disconnect field coil wire from M-terminal of magnetic
switch.
(2) Connect a 12V 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.
HOLD-IN TEST OF MAGNETIC S~WITCH
(1) Disconnect field coil wire from M-terminal of magnetic
switch.
(2) Connect a 12V battery between S-terminal and body.
Caution
This test must be performed quickly (in less than IO
seconds) to prevent coil from burning.
(3) 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 (16volt 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 battery voltage shown on the volt-
meter reads 11.5 volts.
(7) Confirm that the maximum amperage draw is within the
specifications and that the starter motor turns smoothly and
freely.
Standard value:
Terminal voltage 11.5V
Current Max. IOOA
Speed Min. 3,000 rpm
