I don't believe it's the transport since its one I use for my machine setups. It's a WBA 12 that only flashed with 3.75 so it doesn't accept the new 100's. it's never given me a problem before. I first thought it was the MPU, but I had it happen on a known good MPU. That's when I found the thread that Buzz mentioned the harness from the Bill Val could be the problem. I have a parts doner in the garage, I'll go see if it has that harness still in it..
Thanks, Gary
