I installed the other half of the main wire harness for my Hamilton ACW-5 and I want to kill someone now! I am very mad at the tech at Hamilton that told me the main wire harness would fix the problem. Obviously my problem is not fixed! I called Hamilton and tried to talk to Heidi (which Randy Nix told me to talk to the first time) again they would not let me talk to her. I left a message with a random person and talked to another tech without a clue and decide to wait till tomorrow.
