12 volt light question

[mineralslee]

Purchased the coach about 6 months ago. The left sconce fixture over the couch didn't work, the bulb obviously blown. I initially had trouble getting the old bulb out, but finally managed to get it dug out and changed. My issue is that the light still doesn't come on. The fixture on the right side of the couch works fine, not the left one. I tried another bulb but no luck. I tried to test the wedge socket with a volt meter but couldn't read any voltage. ( meter on 15v DC, a probe inserted in each side of the wedge socket) I'm not sure I'm testing correctly. I took the sconce off the wall...everything looks normal. Any advice or information would be appreciated.

Follow-the-wires is always a good adage. Verify as you trace to find the open circuit.

First, is the power even getting to the non-working sconce? Check the voltage at the wiring behind it like you did at the socket - sockets can fail. Also the ground at the non-working sconce. If not, then perhaps the line feeding the non-working sconce has detached somewhere. It might be joined in the working sconce wiring or at the switch. I'd pull the working sconce and verify the wire nuts (and voltage) there and then look at the switch for the same.

Is there a switch on the lamp base. Bad switch??

Step 2 (you already did step 1) Check for voltage on the wires BEHIND the @(OU@#$@# fixture.
