A couple years ago I really just fell in love with pinball, and after playing at bars and arcades for a while I decided to start looking at machines for the house. I ended up buying Hollywood Heat because it is fairly inexpensive, I love the sound, artwork and I think it is pretty fun for the price.
I have started by replacing all the rubbers, the balls, and I have begun replacing all the lights with LED's. Its coming together and I just want to make sure I do everything in my power to keep her playing well.
So, within my research, I have found that I may have gotten myself into the Volkswagon of pinball machines and while everything is working great now, I do have some concerns about it breaking in the future. I keep seeing the same 2 suggestions with this machine. 1 is the ground mod, which seems simple enough. However, the battery mod has got me scratching my head for the past 2 days.
I took some pictures of the work behind the back glass and it looks like some things have already been done, but I honestly have no idea what I am looking at. I was told that regularly changing the battery would be a good idea and this is why I decided to post here. I am new to the hobby and honestly have no idea what I am looking at.
So, I feel so dumb for asking, where do I change the battery? And, the green wiring looks like it might have been done by the techs at the arcade I bought it from. Can any of you tell me what they might have done?
