I had the same problem, and Dave Bauerle fixed it for me when I lived in Ohio. As I recall, it was a resistor that was bad. A very simple fix, in fact he did it as I was picking up the car. I don't recall where it was or which one was bad, maybe someone else here remembers Jack & Virginia Stiefel 1981 DeLorean Vin 3461 August 1981 Build (Ours)
