I have been trying to troubleshoot my Time Machine ball trough. I am getting good voltage at the coil and the transistor is testing in spec, but the machine doesn't fire the coil hard enough to launch the ball. I have swapped the coil for a known good one and the behavior continues. Is it possible to have a transistor test in spec and still have issues? Is there an IC that isn't clocking the right strength to the coil? Spit balling ideas at this point. Thx
