Hi Guys, I have a small problem with my EL 4 Litre Auto.
I have been working on this car for a while now and now the Econ light is not working.
It was working when I first started and I pulled the ECU out to do some welding and Im not sure if thats when it stopped or not. my question is as far as i know the switch only switches to earth?.
what could go wrong?, could it just be the globe or what else could happen?. it appears to be a simple system, does the computer loose its memory when its pulled out.
sorry about all the questions but it has me stumped.
thankyou, David.

Could be something as simple as a wire not properly connected or that the globe is o/c.
