Hi Folks,
This is my first request for info on this excellent forum (see my intro on how the forum has helped me).
Ive seached high and low for the pinout info, including the #501 repair thread, the Haynes manual (which mentions “designated terminals” but doesnt specify them for the earlier model), as well as any wiring diagrams I could get hold of. I need to check the flap resistances and temp resistance in order to track down a cold idle problem (see separate post).
Maybe its been staring me in the face somewhere, if so, apologies in advance, any help much appreciated,
Thanks
Mark

Hi Geoff,
Excellent, thanks for your quick rsp.
So I can measure air temp across EG and flap position across DF or FC (looks like stepped rather than ‘infinite’ resistances looking at the AFM repair thread pix)
How does the fuel pump switch work? Mine seems to run continuously with ignition on, even engine off…
Thanks
Mark
