Ok I think I have found my answer. After carefully looking over the owners manual, and I mean carefully, I actually saw a small diagram with 2 Lugs on the unit. Take a guess what those are for...you got it, one is pos batt and the other is neg batt. Now to address the rude comments, not everyone is RV savvy, hence the reason they have forums like this. It take a real piece of samsonite to address a noob in the manner that has been displayed. Next time you might want to think about being a little more understanding, and remember the time you were a noob as well. As for the others, thank you for you help. There are people left on this earth with a functioning brain!!
