Need some Earthshaker help and I am at a loss here figuring this one out. Pulled my states assembly out to rebuild it as the cam was having trouble locking. I work on pins for myself and others and this was a pretty simple job. Of course everything done with the power off removing and re-installing. Turned the power back on and nothing but Earthshaker flashing on the display with a speaker tick every second along with the display flash. Looked up in the head to find the white/red line wires that matched the switch wires and found the same wire in the J4 interconnector flashlamp circuit. This is before I found identical wire color which is a switch wire on another connection. Let's get back to that J4 connector though with the matching wire color. If I pull the connector the game boots right up so I could perform a switch test. Switches all test good. Some coils don't work with the connector pulled because they are tied into that connector. States assembly works fine now but the pin doesn't. Now if I connect J4 and pull J12 off the CPU the game also boots up. These would be 2 different circuits so why does it work with either pulled? Nothing pinched, metal touching etc. Why this problem after a minor repair. Location on the playfield there was no chance of solder splash or damaging anything. All that's in that corner is the states assembly and the ball popper?
