Hello, have a problem with our MB207d van. We are just on a holiday trip in the south of Europe, quite far to the next workshop. Had made on the solar system and the batteries, and stupidly still on the light. Had the plus cable off the battery and wanted to plug it up again, while flashes the light up and then it was dark. Ok. fuse— changed. But can’t. The light bulbs are ok. I just discovered that there is a cable from a relay next to it. Hanging, who of you might be able to help me, have no plan what it is for a relay and where the cable gets on it. Occupancy? On the relay is VW311906061C when I get Google’s info —> without light switching mode Suppose it’s on the cable and or the relay is through. Can it be bridges if necessary? What else could I check? Thanks Ben
