Hello,
Recently purchased a new to me F-350 to tow my Sundance 2900MK. I have noted that when I connect the truck to the trailer There is no power to the trailer unless the trucks engine is running. This was not the case with my older truck. With that truck, when the power harness was connected this didn't happen. there was always power to the trailer, engine running or not. Of course this means that if the trailer battery runs down I cannot get power to the coach unless the truck engine is running. Not good for the neighbors nearby. Does anyone have any idea as to what might be wrong?
Thanks Ken
