Just to go over this again, what I believe is happening is you are trying to push power into the battery in one direction in the same wire that you are using to drive the motors which wants to run power in the opposite direction in the same wire. Might work with A/C but I don't think it will work with D/C. I probably would have used this wiring idea because it reduces the number of wires you have to run, but this proves it is very easy to come unstuck
