Testing
1. Disconnect the solenoid from the wiring harness.
2. With a multimeter (ohms setting), check to ensure
that terminals "c" and "d" are open (no continuity)
(Figure 20).
3. Apply +12 VDC to terminal "a" and ground

Switch, Brake

Purpose
This double pole plunger type switch has four
terminals. When the brake pedal is depressed, it
completes the safety circuit for start. On tractors with
cruise control, the cruise control circuit is connected to
the brake switch. When the brake pedal is depressed,
the switch opens and the cruise control magnet
disengages.
How it Works
This double pole plunger switch has four terminals.
When the brake pedal is depressed, it pushes on the
plunger, closing and opening the contacts in the switch.
Testing
1. Disconnect the switch from the wiring harness.
2. Using a multimeter, follow the procedures listed
below (Figure 22):
