MASTERSWITCH REMOVAL OR REPLACEMENT

The Masterswitches can be removed for servicing by removing 4 masterswitch mounting screws and opening the console. As the masterswitch is removed, feed the control wires into the masterswitch mounting bracket.

NOTE: When replacing the masterswitch, make sure that the Y ("-") axis (cast into the mounting flange) faces forward. Refer to the Electrical Schematics, code No. 5P, for wiring diagrams.
