Dutch Star lights don't work

Since you have a fair amount of electrical demand with all those lights, there is most likely a relay (or two) controlling the loads. I will assume you've checked fuses so I would start by looking for a bad or disconnected relay. If you are not familiar with relays, they typically look like small black boxes and often are plugged into a socket on the fuse panel. You can also find them mounted on a panel with a plug-in connector on the bottom.

If you provide the coach and chassis info you may get a better response from someone with a similar rig. Good luck.
