How To Test the Inlet Switch

continued from page 2

The inlet switch is located on the mounting plate, near the cam. The inlet switch sits on a thin plastic or papery insulator and can be differentiated from the holding switch which sits on a thick spacer. The inlet switch also uses only two wires, while the holding switch uses three.

Remove the switch by removing the two screws that hold it in place. The switch is connected by two wires. Label the wire placement on the switch before disconnecting the wires. The wires are connected to the switch with slip-on connectors. Firmly pull the connectors off of the switch terminals (do not pull on the wire). You may need to use a pair of needle-nose pliers to remove the connectors. Inspect the connectors and the terminals for corrosion. If the connectors are corroded they should be replaced.
