Hello
I have recently had various lights fail on my 560 SL and am wondering if anybody knows what the problem could be. I have read about relays and tried switching them (they are both the same) but the problem does not disappear. I believe it may be an isolated ground wire - the clusters of grounds all look good and now I dont really know where to start looking. Specifically the group of lights which are out are: right tail light; front indicators; and instrument cluster lights. Any advice would be greatly appreciated. Thanks in advance.
