I've bought a fuel computer off Ebay to go in my Calibra which is AWOL for 2 weeks having the bodywork done. Anyway I thought I better try it to see if it at least comes on. So with the help of the Haynes guess book I connected 12v live to the all black wire and stuck one of the browns on earth and hey presto I had a display. Problem is it's very feint and only clearly visible when looking at the display from a side on angle. Is this the way it's meant to be or is there some kind of illumination other than the bulb which I failed to power up ?
Talking of the bulb I also wired the other brown to earth and the black/grey cable to 12v but the bulb didn't light up. I've taken the bulb out and as far as I can see it's not blown but no light.
Can someone tell me if I'm doing things wrong here or have I possibly got a fault ?
