All of the indicator lights on my 500i manual have gone extremely dim. Not quite dead, but it has to be pitch black dark before you can see anything. Looks like a ground wire or a connector has become corroded, because all lights went dim, but I went over the harness today and darned if I could find anything.

Anyone have this problem? Know where I might look to find the bad connection? Never knew there were so many wires on this machine...
