Terry let me be the first to welcome you to RV.net and Happy Holidays to you and your family! I own the exact same coach as you a 2004 Winnebago Adventurer. One thing you want to be careful of is the Battery Disconnect Switch it's right on the steps to your left as you enter your coach. Not only do I hit this accidentally with my foot or leg and switch the batteries off. My dog also hits the switch when she enters the coach. Check the switch first! On your Roof you have a solar trickle charger which constantly helps charge your house batteries. If your not aware the 04 Adventurer is Winnebagos top of the line gas coach for the year 2004. Also not having fully charged house batteries can effect other things in your coach like the Kwikee Steps. I changed out all 3 of my batteries last month because they were 8 years old and wouldn't hold a charge and they were causing my Kwikee Steps not to extend or retract. I'm at 14.5 volts now and everything is working. Feel free to PM me anytime as need be if you need help. John
