Inspection
Pinion GAP
1. Remove field coil from “M" terminal of magnetic
switch.
2. Connect the battery between "S" and "M" terminal
of magnetic switch.
CAUTION
Do not try continually the connection longer
than 10 seconds to prevent coil from being
burned out.
3. Slightly push the protruded pinion with hand and
measure the returns (moving distance). This
distance is the pinion gap.
4. If the pinion gap exceeds the reference value,
increase or decrease the number of fiber washers
between the magnetic switch and the front bracket
to adjust the gap to the reference value. Pinion
gap decreases as the number of washer is
increased.
Reference value : 3.0mm
Pull-in Coil Test in The Magnetic Switch
Pull-in coil is normal if the plunger is inserted and
then the pinion pops out when the battery is
connected between “S" and "M" terminals of
magnetic switch. If it does not pop out, replace the
magnetic switch.
CAUTION
• When this test is performed, remove the
connector from "M" terminal.
• Do not try continually the connection longer
than 1 0 seconds.
Holding Coil Support Test In The Magnetic
Switch
Pull out the pinion to the stopper position by hand as
battery is connected between "S" terminal of
magnetic switch and body. If pinion returns when It
is released, holding coil is normally functioning.
