I have a trailer that has a battery powered hydraulic system on it. I want to hook it to the truck charging system to keep it charged. My first thought is to run a small wire(8 gauge?) from the truck battery to the trailer battery. The problem I see with this is that when the trailer battery is being used and starts losing power, the hydraulic system would begin pulling power from the truck battery. This drain would go thru the 8 gauge wire and burn it up. Do I need to run a large battery cable all the way to the trailer? What size? Am told welding leads are good for this. Also told that 4/0 copper entrance cable would be better, but very stiff to work with. What kind of disconnect plug would be good? Would appreciate any suggestions. Thanks, Chief
