We have a 2017 Discovery 37R. The awning strip lights will not turn. When I go to turn them on at the panel it shows that they are on. I followed the wire for the light up the awning arm and un plugged it. I am not getting any 12 volt power. I used a 12 volt battery charger and hooked it up and the lights worked. I cannot find a fuse for it. Any idea where the fuse would be located?
