So...with the hopes of replacing the worn 1156 light socket in the porch light over the door of Alex, my 1975 Argosy 26, I cut the two wires to the socket and removed the socket from the light cover.
I attached a new socket with brass wires to the porch light wires - white to white, blue to black. However, I've somehow killed the entire circuit, so the porch light, the two lights over the front couch, and the front ceiling light aren't working. My multimeter is not picking up anything at any of those four lights/their wires, including for the switch for the porch light and the plug for the fluorescent round tube on the ceiling. Installing a new switch for the porch light didn't seem to help.
The fuse for the brown wire (which I understand is the wire powering the circuit for those four lights) is good, and everything else 12V
in the trailer works (always knocking on aluminum
I know I opened the circuit and need to close it again; I can't figure out where the problem lies. Is it joining aluminum and copper wire (not a good practice, I know)? Not grounding the new 1156 socket by not riveting it to aluminum? Pulling the wires for the porch light or its switch too hard? Something else altogether?
Alex the Argosy and I are headed out to the Rocky Mountain Vintage Airstream Rally in Colorado next week; I'd love to fix the issue by then but, more importantly, make sure the old boy will be safe with this issue, regardless of whether I'm able to fix it before the long drive or not.
