Last fall I had a mechanic take out my batteries. It was easy to get the engine batteries back in. The coach batteries though have not worked and there are three loose wires that I can't figure out where they should go. I took it to a place that works on trailers and they could not figure it out. Can anyone tell me how to wire the batteries? I have them in parallel but they are not going to the house and there are these three extra wires. Please help or send me a picture of your coach batteries correctly wired including these three loose connections. I am using 12 volt deep cycle batteries.
