First Pin / First Pin Repair Attempt - Dolly Parton
Made a lot buy over the weekend, and included was a Dolly Parton pinball machine. I power it on, and all the lights come up, but the system dosnt boot. No displays, no lights on the mpu, nothing.
I got good voltages at each of the 5 test points on the transformer, but the only one with voltage on the mpu was TP3. I was told this machine was a common KISS conversion and started basic diagnostics with those schematics, but there are somethings that im sure are different. For example, pin 8 of the power transformer board is an orange wire that goes up next to the solenoid driver and is just hanging there. The schematics didnt list where that goes. Its listed out of the transformer as A3J3-12, but I couldnt find that referenced anywhere.
Does anyone have schematics for this, or any advice on what to go after first?
Thanks
