We have a 1680 1992 model, I put a heavy battery down on the front axle next to the reverser and tied it in series with the others up top, has helped a lot, I had the same problem, my dad is 83 and likes to drive the combine for a couple hrs but has to rely on the reverser, has not had it refuse to unplug since I put the 3rd battery on. Hopes you find the same.
