No Power to interior light swith...

[Pigpen29]

So I have a new 5er, with slides and 4-5 light switches for different interior lights in the living room area. All of a sudden, one bank of 4 lights, controlled by 1 rocker switch, is not working. All other lights and switches are working. I ruled out that the switch is bad, changed it with another one and it works fine. I touched the two wires that connect to the switch for the light bank in question and the lights do not come on...thus no power in the wires going to the switch. Fuses in fuse panel are all fine. Also looked at wires under the slide to see if one got pinched and they look fine.


Any suggestions for what to look at next? Thanks in advance!

all the lights in my main cabin operated by the wall switch also have switches on the lights themselves. You didn't have a guest or someone come along and flip them all off not knowing there was a wall switch did you?

Did you check the lights? There is a little switch on each light. Someone may have turned them off at the lights.

Get a 12v probe tester to check the power to the light switch.

Nope...they do not have switches on the individual lights.

there are no switches on the individual lights and there is no power to the switch.

'No power' to switch sounds like a fuse. With an pick probe you can test each fuse and even test to see if you have a good ground.

I googled '12v circuit tester how to use' and found this youtube:
