So here is a weird one. Or maybe it's not. I dunno this is my first pinball machine. Anyway, my right flipper started sticking on my Star Shooter so I popped the hood to see what is going on. The game is in really good condition, the person I bought it from did an amazing job restoring it. I knew the problem was electrical because the flipper stuck in the up position would drop once I turned the game off. Basically what is happening is that my leaf switch on the flipper button is getting stuck closed. My first thought was corrosion but like I said the game is in really good shape and I don't really see any, although I may be bad at spotting it. The thing that I think is really strange is that the contacts only stick to each other when there is power to the game. I can press the button while off 20 times without anything sticking but when there is power to the game I see some arching when it doesn't stick and it will always stick within 5 contacts tops. Are my contacts somehow becoming magnetized? What should I do to fix this? Is this something that you have heard of happening? Should I clean? Lube? Replace? TIA
