I have a 2016 Hurricane 29M. The control module under the king size bed is not telling my 12 volt power to turn on when I unplug the shore power or turn off the generator. I traced the hot power to the module from the battery and it is on. The cable coming off the module to the fuse panel is staying off. Is it the module or some sending unit from the generator or shore power plug? Is there some simple test to find out?
