I have a 39S Discovery Diesel Pusher w/ Cat engine. It is a 2003 model on a Freightliner Chassis. Apparently I have blown a fuse on the Tow plug-in on the back of the coach. I do not have power for the running lights or turn signals at that plug. Does anyone know where the fuse for this is. I have tested the fuses under the center of the dash and at the back at the electrical box. All the fuses I have checked show to be good. If there is a fuse for this, what name would it be listed under?
