I was just looking at that over lunch. I saw where there is a way to test it. I think I need to pull that switch and test it. I also think that I should hook up two volt meters (one to each) fuel pump and see what happens in terms of power supplied just prior to shutting down. I wonder if I can test the overboost switch in place? I would guess it grounds out and causes the overboost relay switch to kick in.

also a note, I don't have a "yellow" squarish over boost relay in the rear panel. In it's place there is a "red" round relay like one that should be in the fuel pump relay spot. I wonder if that is the problem. What is special about the "yellow" overboost relay?
