We purchased a battery tender junior today and got a little confused when reading the instructions. It says that if you have the battery outside of the vehicle, you have to attach a 24" (minimum) 6 gauge insulated battery cable to the negative terminal. Then, after you've attached the positive clamp to the positive terminal, you attach the negative clamp to the open end of the 6 gauge cable. Is that last really necessary? Can you just use the negative terminal instead of having another cable? Anyone have experience with this?
