Cruise Control Switch Test; Brake Pedal Switch Tests - Simplicity Broadmotor Series Service & Repair Manual

K. Cruise Control Switch Test
The cruise control switch has a N.O. contact and closes
when the cruse control is engaged.
SWITCH TESTS
NOTE: It may be easier to test the switch if the switch is
removed. See Component Location and Replacement for
switch removal procedures, earlier in this section.
1. Pull the wire harness off the back of the switch.
2. Set VOM to Ohm. With the cruise control knob in the
disengages position (plunger not depressed) probe
the switch terminals (see Figure 35). The VOM
should show continuity (zero ohm).
3. Engage the cruise control knob. Probe the switch ter-
minals (see Figure 35). The VOM should show conti-
nuity (closed).
4. Replace a switch that does not pass all tests.
L. Brake Pedal Switch Tests
The foot pedal switch has two terminals and is a normal-
ly open switch.
An N.O. contact is normally open, meaning that when the
brake pedal is at rest (up, not depressed) the switch is
open and will not conduct current. Depressing the brake
pedal (or switch plunger) closes the switch.
SWITCH TESTS
NOTE: It may be easier to test the switch if the switch is
removed. See Component Location and Replacement for
switch removal procedures, earlier in this section.
1. Pull the wire harness off the back of the switch.
2. Set VOM to Ohm. With the brake pedal up (plunger
not depressed) probe the switch terminals (see
Figure 36). The VOM should show no continuity for
N.O. contacts and continuity for N.C. contacts.
3. Depress the brake pedal and engage the parking
brake.
4. With the brake pedal depressed (plunger depressed)
Probe the switch terminals (see Figure 37). The VOM
should show continuity for N.C. contacts and no con-
tinuity for N.O. contacts.
5. Replace a switch that does not pass all tests.
