Todd,
I had a similar adventure with my 1981 Bradley GTII that I bought used last year. It was my third drive to work and I had just turned the corner and the pushing the pedal the car did nothing. I coasted into an office parking lot and parked the car. This car is low to the ground, so I could not determine the root cause of the problem, and I was close enough to work to walk. My wife picked me up and we got appropriate jacks and stands and safety equipment to allow a more through investigation in the parking lot, as it was a nice sunny warm day last late spring. We went for a walk and looked for missing parts on the street but did not find what we thought were the ones from the car. Fould a lot of other interesting small parts. I did try a hose clamp but it pulled loose. Finally had the car towed home. I called the person that sold me the car and he gladly came by and helped - he removed the pot box from under the car and we found the hole in the pot box arm that the cable goes through, that I could not find from under the car. The cable had broken. I went to the hardware store and purchased new cable and end clamps. My son and I replaced it and it worked fine. But the car's contoller was original (old fork lift controller) and was not working well -sometimes got stuck and ran the motor full blast in neutral or would not power when the accelerator was pushed. Plus the car was a dog in terms of acceleration. I called John Emde and asked if he could upgrade the controller. Wow - now I have a fast car that runs great and he replaced the cable system and pot box too. Can't say enough about his great work. Thanks John and John.

I still need to get a picture of my car on the board.
