7. INSPECT MAGNETIC SWITCH ASSY

INSPECT MAGNETIC SWITCH ASSY


(a) Check the plunger.

  1.  Push in the plunger and check that it returns quickly to its original position.

If necessary, replace the magnetic switch assy.

INSPECT MAGNETIC SWITCH ASSY


(b) Check if the pull-in coil has an open circuit.

  1.  Check the resistance between terminals 50 and C.

Standard: Below 1 W

If the result is not as specified, replace the magnetic switch assy.
