2009 mountaineer 29.5.12v power
New member so this has probably been answered many times...do not seem to have 12v power anywhere. No light, no slide power, nothing. Battery new and fully charged. Battery cables correct. When not plugged into 120 I have nothing. Had 12 volt power before new battery BUT had this issue: battery ran down within hour of charging, ok I changed battery, it's charged but nothing works. (That's fully charged.) Breakers are all on and checked all fuses I can find. I'm confused. Ideas?
