I have a problem that is making me a bit crazy. My glow plug light does not come on and the timer relay does not click. I tested the plugs, they test good. I checked the bulb, it works. I checked for voltage to the timer and across the strip fuse, all good. #12 fuse, good as well. I have replaced the timer with one that I believe to be good to no avail.
Is there anything else in the system that would stop the the timer relay from operating? My car is a 1985 300D California spec.
