Hey there! I recently went out for the weekend and I was not drawing any power to the unit. I am hoping that it is just the house battery (surprised there is only one) and not an electric issue. I checked all the fuses and breakers. I did replace the truck battery just before I went out.
... guessing you don't have DC power in the coach. Is the house battery switch on? Probably mounted low near door and might have a lighted indicator for "on".
Yes, the connections were all on. I just replaced the house battery and everything is working with the generator with no issues. I will check with a direct hook up at our local RV shop.
