Hi! I just bought a '64 Gottlieb Bowling Queen that has been in storage for a long time. Was making progress on fixing various relays and rollovers, all the while score reels seem to be working fine. They were incrementing correctly and reseting as they should. However, now the "1"s reel is getting stuck. Its unable to increment, which means when the game trys to reset to 0, it just clicks and clicks trying to get it to move, but it doesnt. If I manually push the coil plunger, all the mechanics seem free and it increments with ease. It feels no different then the "10"s and "100"s reels that are working without issue, so I'm inclined to not think its a mechanical issue. Sometimes it gets it and works briefly, but also gets stuck eventually. When it is acting up, it's like the coil doesn't have enough umpf/strength to get to the next ratchet tooth.
Is the coil just shot? Or something else at play? I'm an EM noob and have reading through http://www.pinrepair.com/em/index2.htm#reels to try and figure this out.
Would love some recommendations or advice! Thanks in advance!
