heres something out of the factory book
I can JUST read it... could you possibly scan it at a higher resolution?
did some researching though...
Cold Feed Switch (CFS)
Screwed into the head from HZ on. It's function is to prevent vacuum spark advance until the Engine Temperature exceeds 65 degrees C to minimise emissions.
Trans Controlled Spark Switch (TCS)
Mounted on the gearbox, This makes contact when in high gear only and controlled the timing advance, part of emissions.
CFS & TCS working together
The Transmission Control Switch (TCS) is mounted on the Gearbox and only permits Vacuum Advance to the Distributor when the vehicle is in Top Gear. The purpose of it is to reduce emissions during the warmup phase.
It is placed in series with the Cold Feed Switch (CFS) switch on the Engine so that full Vacuum Advance is only available when the engine is at or above 65 degrees temperature and the car is in top gear.
Anti Dieseling Solenoid
Mounted on the side of the carbie, The anti-diesel solenoid is used to prevent engine run-on after the ignition switch is turned OFF. The system uses a valve to shut off the supply of fuel to the primary low speed circuit, when the engine is turned off. The solenoid is normally closed and when energized, the needle assembly retracts, allowing fuel to flow through the primary low speed circuit.
Temperature guage wiring still eludes me??
Still can't find the temp gauge wiring... yes i know where the sender unit is and so on... but just curious why its not in the diagram?
so you can see how they all interact and what you "could" get away with removing... but if they work... and you have them... better off with them! :thumbsup:
