A faulty solenoid switch can be replaced separately. To remove the solenoid switch, first remove the starter as described above. Remove the nut from the field-winding connecting strap shown in Fig. 6-1 above, and remove the strap from the solenoid. Remove the two screws holding the solenoid to the starter, lift the solenoid plunger's pull rod up and off the engaging fork, and remove the solenoid. Installation is the reverse of removal. Apply a sealer to the screw heads after installing the solenoid.
