Hi all. I'm currently trying to get the choke warning light to operate on my 1975 2200 TC. It's never worked since I purchased the car. Looking in the manuals, I have one which illustrates a switch attached to the back of the cable pull, behind the speaker grille, which doesn't appear to be fitted on mine, and another manual shows an Otter switch as part of the thermostat housing, which I do have. Is the light supposed to show as soon as the choke is operated from cold, or does it come on when the car's up to temp but the choke has been left out ?. Also suggestions for testing said switch would be gratefully received. I know the panel bulb is ok as I've swopped it. Thanks.
