Inputs and Outputs

Various switches provide information to the SMEC. These switches include the speed control, neutral safety, A/C compressor clutch and brake lamp switches. If one or more of these switches is sensed as being `on', the 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.
