Help With Coin Switch

Question: Hello, we are a video game retailer here in the UK. We have got 3 arcade machine that we have had for a few years now. Just wanted some info please, 1 of the arcade machines has started to add it’s own credits to it as soon as we switch it on. The counter coin on the bottom just starts to click very loudly and adds over 99 credits to the machine. Do you reckon it’s the coin slot itself or something else? Thanks. Its so hard to find anybody in the UK about arcade machines…

Response from Jonathan: It sounds like you are having an issue either with the coin switch or a short in your coin door wiring. We would recommend doing a continuity check on the coin switch with your multimeter to see if it is behaving properly. Keep in mind that coin switches are usually connected to the NO (or Normally Open) side of the coin switch. If it’s connected to the NC (or Normally Closed) side, it could cause the behavior you are describing. If the coin switch is good and connected properly then it’s possible you have a short in your wiring somewhere. Check all of your coin door wiring for broken, cut, frayed, or damaged wires and do some continuity checks with these wires going back to your main board.

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