I have a S6000 Dragon Spin and the MPU red light is flashing. I believe that I may have shorted the handle solenoid drive on the MPU and possibly upstream components.
A little background, the handle would not activate with manual bet of 1-5 credits. I reached into the cabinet with power on to release the handle before I determined the solenoid had a loose wire. I believe at that point the loose wire may have grounded on the metal bracket.
Looking at the schematic for this MPU (AS-83356-0424), I cannot identify which transistor drives the solenoid. It does not appear to be listed on the schematic or possibly shares the drive transistor with another component? I'm no expert reading these diagrams, looking for some assistance identifying the drive circuit for this solenoid.
Any help appreciated.
