Hey guys and gals.

I am looking into a solution for a problem. I have recently gotten a fifth wheel frame (from a camper minus the body) and am wanting to put together a power system on it. I have a regular automotive battery but have some trouble with the power system that I have been using on my truck. I have a fused line coming directly from the batteries in my truck to the 7 blade trailer connection at the back. This fuse blows pretty stinking quick if the auxilliary batteries that I am connecting to are low. I want to limit the flow into the aux batteries to about 10 amps and reduce it automatically when the batteries are charged so they don't try and fry. Budget is an issue currently but I do have some ability to build what I need with a schematic. Any thoughts or other ideas? At this point I am open to almost any suggestions.

look at a one way diode onto the positive side.. it allows it to charge but the wire that is going back from truck to plug is not heavy enough for that kind of amps (made to charge motor cycle sized dry cell battery).. you should run a direct charge wire from front to back and put a voltage and timer if your trying to charge a car battery.. suggest a good deep cycle battery
