Not sure if this is the case but some coin switch - printed circuit board interaction on whatever equipment requires the board to see or not see ground. That is how the logic within the board deciphers if the switch was made by the coin. Think about it ... if the common wire to the coin switch does not have a solid enough path to the needed ground wire then a loose connection within that path could cause the problem &/or intermittent problem. It is possible the techies from Dexter do not thoroughly enough understand the exact interaction & therefore the most direct solution.There are other things in the world of electronics that also switch on zero or ground so it is good for us to pay attention to that possibility. It could make multimeter testing a bit trickier ... not to mention the fact that the pulse could be as fast as 50 ms which is 50/thousandths of a second.I remember a dear friend who passed away used to service the two hand me down from local banks Brandt coin counters that we had bought used to help with sorting & counting of our coins. He often had in his hand a nifty pulse counter ... anybody like Phu or whoever who invested in one of those & knows thoroughly how to use it? An idea for a new app for pulse testing for our smart phones ... us coin people are not just waiting but are willing to pay for that type of testing device ...That friend while he was still young enough ... took a lot of pride in making sure all our region's banks had coin counters in perfect operating order. It almost seems like he was from a generation who cared about accuracy & not for just relying on the more "fly by night" dark internet susceptible way of processing money!!!
