Park Brake Switch Test
The parking brake switch is a single pole plunger type switch (normally open)
with two terminals. When the plunger is depressed (parking brake ON), the
circuit closes and there is continuity between the terminals. This allows battery
voltage to flow to the rest of the safety interlock system.
Parking brake ON, the switch should have continuity (closed).
Parking brake OFF, the switch should NOT have continuity (open).
