I own a 1996 Newmar Dutch Star diesel pusher which I purchased about two years ago. I thought the house batteries were weak and inspection revealed the four batteries were not from the same manufacturer but they were still doing the job and we never dry camped so I went with them.
Before a trip I would bring the coach home and plug our home 120 AC into the plug behind the fridge panel on the exterior of the coach. The idea was to cool off the fridge before hitting the road. Once on the road the fridge kept cool with the propane gas. The last time I tried to use the 120 AC from our home to the fridge, the fridge would not come on with the AC or gas. No lights on the fridge door panel at all. I replaced the four house batteries and the fridge and interior DC light still don't work. The fridge and interior light come on if I run the generator. I suspect there is a fuse of some sort which has blown. Any idea where it might be on my coach if I happen to be right??
