Stunt Cycle : has life but no throttle or gameplay

Did you check your voltages?

If those check out then it's time to break out the logic probe.

The Sound might be a sound effect always stuck on.

The Schematics are pretty nice and detailed as to what does what.

Hard to tell from the video, is the motorcycle just doing wheelies or is it tumbling like a bad jump?

No voltage checking yet...and motor bike is doing normal riding, tubling and crashing...its all random.

I might be a little radical and pull out chip k11 to disable all throttle inputs for the game and see if that removes the problem with the sound and the bike tumbling and being off line. if it does it gives us an idea of where to probe for the true problem. removing that chip takes disables all throttle control that you can put in and for the attract mode too I believe. socket the chip anyways after you take it out.
