Throttle Full Open Switch: Description and Operation
Micro Switch Location
PURPOSE
The microswitch (S27/1), which is located near the cruise control actuator, senses full load throttle position.
OPERATION
With the throttle in the full load position and the engine between 1050 and 2150 RPM, the compressor is cut out by the microswitch via the compressor
cut-out control unit. Low engine speed performance is improved by this operation.
