The power switch has to be on. Check all your circuit breakers. Check the GFI in the bathroom. The hunt for the converter is a fun one. I posted pictures of where I found mine in a earlier post. If it is a stand alone, it will have 1-2 fuses and an indicator light red/green. If you have a 12v outlet, Check to see what voltage you have when you are plugged in. Mine was reading 12.1 and every time I turned on a light it dropped about 2 volts.
My converter was under and all the way against the wall under the bathroom with the tabs on one side, under the wall. I purchased a new converter (amazon) and disconnected the battery, took a sawsall to the 12v power cables. The AC plug was in the back of the power panel. Re connected the 12v and the AC. Turned it on and the voltage went up to 14.1 and slowly dropped to 13.4. Everything is working great. Mine was a stand alone unit
