Documentation

The Bally tester PCB comes with 3 connectors (J1, J2, J3) which are pin compatible to the connectors available on the original MPU. Connection of J1 is needed as a minimum as the tester is powered via J1 pin 16&17 (5Volt) and J1 pin 18&19 (GND). Connection of J2 and J3 are optional, depending of the things you want to test.

overview: 

J1 (Equivalent to J4 on MPU): 5Volt power supply of tester PCB; test Sound & Solenoids; test zero cross signal (LED on PCB)

J2 (Equivalent to J1 on MPU): test lamps

 J3 (Equivalent to J3 on MPU): only needed if you want to start/stop the current test from
