We are on the road, currently in Provo, UT on the way to West Yellowstone early tomorrow morning. It is of course Sunday, so not much we can do here today. We drove in last night and just as we started to pull in the RV site, our Voyager went blank. We have a 40ft 2007 Holiday Rambler Ambassador. Electrical issues isn't exactly something I am particularly good at. We checked the breakers and fuse panel and all seemed normal.We even pulled the dash system out to see if there was a fuse there, and found one, but it looks OK. BUT, the radio, that is part of the Voyager dash system comes on. I don't think this would be related, but this morning we started to use the central vac system and it doesn't work. We went out to check the vac in the hold, unplugged it, plugged a light into the outlet, and it didn't work. So perhaps we blew something relating to both. Everything else seems to be working fine. AC is on TVs work, lights and outlets in coach all seem to work. Any idea what has happened?
