Hey all!

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?

Oh that is great news! Thank you very much for your response!

Any Ideas on what all the green wiring might be?

This is the video of the ground mod I saw:

Again, not sure how important this is,

I really appreciate everyone's input here! I cant tell you how much better I feel. Tonight I breathe a huge sigh of relief and, to your point LTG, lots of fun to be had.

You guys are great! Thanks again!
