Response from Jonathan: Mike,

We are not as familiar with cherry master boards as we are with other coin-operated game boards. With that said, it looks like the dip switches for your board can be found here: http://www.arcaderestoration.com/gamedips/1583/All/Cherry+Master+91.aspx. 8LineSupply also sells a manual for this board that should give you some additional information that might help you with your other questions: http://www.8linesupply.com/p/cherry-master-91–dyna-game-manual.html. Our friends on the New Life Games forum have a section dedicated to Other Arcade and Amusement Games that specifically includes cherry master items: http://newlifegames.com/nlg/index.php?action=forum. They will probably be more helpful at troubleshooting your issues as they have more experience with these boards. Of course, feel free to contact us again and we’ll try to help you out as best as we can.

Hope that helps. Thank you for your question and good luck with your future repairs.
