October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Engine Speed Switch

Switch determines engine RPM and completes electrical circuit to 3-way solenoid when more than 1000 RPM (Federal) or 1100 RPM (Calif.) is sensed.

NOTE: On models with air conditioning, the air conditioning relay is in-line ahead of engine speed switch. Whenever A/C is in on position, this relay will activate throttle positioner system, allowing slightly higher idle speeds.
