Figured it out. It must have been the bulb after all, and maybe the fuse. I changed the fuse and checked with what I thought to be a good bulb - no light. Then checked the connector for voltage and, lo and behold, there was 13.8 volts at the connector, so I tried a different bulb and it worked. Phew...

Hi list - New member here. I have an '89 765. My right low beam has suddenly gone out. It's not the bulb or the fuse (replaced both with new ones). How likely is it that the relay would suddenly poop out with no warning? Any way to chech the relay using a standard VOM? Other suggestions? Thanks, Pet...
