Hi to all I thought I would ask if anyone else has had this problem. For some reason my check engine light will not light when the ignition is turned on. I pulled the cluster out and was checking the bulb holder and found this. When I put the test light to one side of the bulb holder the bulb lit up, when I put the test light on the other side of the holder the test light lit up. I checked and there is power to one wire and no power to the brown wire. I hate these little problems like this finding the problem can be a pain so hopefully someone has had this problem before, thanks for any help, oh by the way it is a 88 325is.
