First off thanks for the reply to my post. I made my post back in April and if I remember right I found a problem with one of the control transisters but I am not realy sure, We have so many trucks come thru it is hard to keep up with all of them ( we rehab used trucks for resale ). I do know that I got it fixed and it was sold and I must of got it right because I never have heard any thing back on it.
