Our Silver Cloud
has 4 exterior lights
: one each front and back and one on each side. The rear light
and door-side light
work fine. However, the front light
only operated for a short while after we bought the trailer and I don't know if the side light ever worked for us. Both have good light bulbs and I've switched known working bulbs to test the fixtures. No luck.
Next, I tried my multimeter with varied results. The side fixture shows no power at all, so I need to take that one off to see if the connections are bad. The front fixture shows 3.48 volts when I touch the two leads to the poles of the switch. When I reverse them, it reads -0.00. I understand the lack of reading on the side light - no power or no ground. What does the 3.48 indicate for the front light? Bad partial ground? If so, where does it ground to? The fixture has a metal backplate with a white ground wire screwed into it. However, the fixture screws to the fiberglass, so no metal to ground to there. The front light did work for about a month after we bought the trailer.
Any ideas? By the way, I do enjoy learning from everyone here. Every day is a new adventure!
