Question Electrical Question on FD Unit

I was running the wire for my FD chip detector today and discovered that my FD unit is not grounded to the main cycle. Is there a reason for this that anybody knows of on a 2000 model year?

Hello Dean

I would say it is not grounded because it is not an electrical device . From what experience I have BMW is good about not using frame and other metal structures as a ground / 12V neg electrical path , just shows their attention to detail .

Re: Electrical Question on FD Unit

BMW does not use frame grounds on their bikes or cars. They wire every electrical device not on the engine with separate grounds (brown wires) Look for a ground terminal somewhere with brown wires to attach a new one. There is one right behind the battery. Or for a small load such as the one you are working on, find a brown wire to another device and splice into it. For anything above an amp or two, you should find an existing tap point or go direct to the battery to avoid ground loop noise problems.
