You should be able to use the old main dropout short harness on the Tow/Run switch to fix the issue.

David with RevolutionGolfCars.com should be able to confirm the symptoms with You.
Thanks for the info. I can confirm that mine does have the diode. I traced many wires when I changed the batteries. Do you think the diode is bad or something else?
