Quoted from HeyNow:#3 The battery seems to be directly attached to two wires. I was assuming I'd just have a battery holder and pull it out. How should I remove it? Not really sure if I should just use force and pull the wire off the battery or cut the wires as close to the battery as possible.
Once the battery is removed am I able to still turn on the pin?#4 What is a good way to remove a post near the side rail? It is to close for my socket and a tight fit with my pliers that I don't wanna scratch the playfield. I'm sure there is a good pinball vet secret to this.
Remove the battery immediately and replace with an external battery holder. The game will work without a battery but won't hold High Score, Bookkeeping , etc.
Do you have Ignition wrenches? They're small wrenches. They may fit in there. If they don't and you have the cheap Chinese ones, you can bend the handle so the open end is 90 degrees to the handle.
