My pachinko has seen better days I picked it up from a family member who did not care for it properly. I'm having electrical issues. I think when my grandfather originally purchased this machine and fixed it and from my understanding of the vague manuals and pictures I've seen he replaced the battery so that it could be plugged in. I plug it in and nothing happens, I've used an electrical tester and it is saying all lines are getting power as far as I can tell but no lights or any activity is happening. Please help, even descriptive manuals in English would help.
