Throttle Opener System: Description
The throttle opener system consists of throttle opener assembly, solenoid valve, engine speed sensor and air conditioning switch. Various models also have provisions for heavy electrical and/or power steering load switches in addition to air conditioning. These include power steering, oil pressure, lighting, defogger and blower switches. When the engine speed sensor detects engine speed at or below specified value, air switching system does not operate. When engine speed is above specified value, air switching system works as designed.
