I'm working on restoring a Gottlieb Central Park. While working on it, this symptom started up:
The 'ones' unit will cycle through to '0' then the coil in the ones unit locks on solid until I pull the power (to keep it from melting down, then it advances to '1' as the power goes off). I've had the ones unit apart 3-4 times already looking for a short or mis-adjusted switch, and just cannot find anything. If I plug the power back up, lights are off until I hit the replay button again, then the process of cycling through to '0' and locking the coil on happens again.
I have the schematic, but admit I have a tough time tracing what is (or should be) going on during the reset sequence.
Any tips of where I should be looking?
