Brian,
I have a 2006 Discovery, so not sure where the fuse panel would be on your 2016. You can contact Fleetwood @ 800-322-8216 give them the VIN for your coach and they should be able to answer your question. They will also send you electrical, plumbing, and TV coax diagrams for your coach, that can come in handy when trouble shooting. Also not sure if you are aware of the Discovery Owners Association. Great group to belong to. Only Discovery owners. They have a forum that is monitored by many very knowledgeable Discovery owners that can answer most any question. Check it out at
