Towed vehicle battery dead upon arrival at destination

[Pat O'Sullivan]

This summer we installed a Blue Ox tow package with a Stayinplay braking system. I own a 2007 Newmar Canyon Star 3303 which according to all info I have, it will keep the towed vehicle's battery charged while driving. Our first trip away resulted in a dead car battery when we arrived at the RV Resort which was embarassing and required a boost. This happens when I drive more than 4 hours without checking on the car during the trip. I checked for current at the plug in and got none. I spoke with the installer who said that it might be a blown fuse. Now I have to figure out which is the right fuse. Does anyone know exactly where the correct fuse box is located and which fuse it is?

It can only keep your battery charged if you are running a 12 volt charge line and connecting to your battery via a charge controller.
