Hi Everybody, I have a 1980 sd300 and my instrument lights are out.
I checked and the fuses are good, does anyone have any suggestions
as where to check next? Thank, RonnieJoseph

 

Ronnie, Fuses are good , but do you perhaps have a corrosion issue between the fuse and the fuse holder? To check I use a long jumper wire and hook it on to the negative post of my battery. Connect my cheap test light to it. Turn the lights on and touch both the inlet and outlet clips holding the relevant fuse. Your fuse may light the lamp but the outlet clip may not. This is a known issue with older VW cars as well. Allan

 

Thanks Allan, I'll try that. RonnieJoseph
