Reliant L4-153 2.5L SOHC (1986)
Air Conditioning Switch: Description and Operation
Various switches provide information to the logic module or SMEC.
These switches include the idle, neutral safety, A/C compressor clutch speed control (1988) and brake lamp switches.
If one or more of these switches is sensed as being ON, the logic module or SMEC signals the idle speed motor to change idle speed to a pre-set
RPM.
In addition, when the A/C is ON and the throttle plate is above a specified angle, the wide open throttle cut-out relay prevents the A/C clutch from
being energized until throttle angle is reduced.
