Quoted from Boatcat:Agree totally! In the business, we used to re-wire many of them to count coins, not games.
My Roller Coaster meter was re-wired to count coins, and had 191,000. I don't know when it was switched to coins, but the counter was broken.
I opened it up and fixed it using a cut piece of tie wrap. Apparently the coil would actuate and index the number half way, but when the coil released, it would not complete the indexing the full number. That portion of the plastic spring was broken, so I Magiever'd it with the plastic tie wrap. Works perfect now.
I'm going to rewire it back to count plays. From the pictures in this thread, it looks like I have to move one of the counter wires to the wire that is screwed into the wood next to the meter.
