As I'm not much of an electrician, I'm asking for some advise. I've noticed in the last few nights the 12 volt lights flickering...dimming, then getting bright again. It's not just 1 light or group of lights, but it seems that every light in the rig I've checked does it. Doesn't make any difference if there is only 1 light on or several of them. I've got a Progressive 50 amp EMS installed. We don't have a genset, and no gen. prep. One issue I did have last week was that I noticed an issue with the bedroom light, took the switch out & the wire came out of the solderless connection that hadn't been crimped properly. I'm hoping it's not the converter!
