How To Test the Inlet Switch (continued)

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.

Test the inlet switch

Test the switch for continuity using a multitester. Set the multitester to the ohms setting X1. Touch one probe to the side terminal and the second probe to the other terminal (if there are three terminals, test the terminal that had the wire attached to it). The reading should be zero. With the probes still in place, depress the switch, the reading should change to infinity.

If the switch fails the test, it should be replaced.
