Remove the 'rake' simply by taking off two screws that hold it.or stick folder pape in there to keep the rake from going thru the entry slot/hole. Turn it around and you'll see how the rake is attached. Simply pull off the Coin Comparitor from the four plastic clips that grab the pins on the CC.

Sometimes you get lucky with this method and scrape off enough gunk to get a better connection. Sometimes you can find metal circuitry de-oxidize stuff in spray cans at auto parts stores too.Īuto guys buy it to clean battery terminals.Īnother thing you can try is to simply remove the connector and put it back on.back and forth, back and forth to somewhat clean part of the pins for better electrical contact. Has a lot of alcohol and dries on it's own fairly quickly. Most guys buy this stuff in a can called 'De-Oxit' and simply spray onto male/female pins in machines. Then simply wipe the pins with a water wet Kleenex tissue.

You CAN make a paste out of one tablespoon of baking soda into one cup of water.Īpply it with an old toothbrush to the pins and watch the battery oxidization/pin corrosion bubble right off of the pins! What happens is the two pins that make up the power connection between the magnet and the circuit board get oxidized.or a circuit board component starts going outta specifications.Īnyways, pull off the two gray wired connector from the y to clean the male pins with something that cleans batteries like on your car. It works by a magnet with two gray wires going to the top of comparitor case enclosure. Behind the coin comparitor is something we call a 'rake'.it's clicking like crazy.haha

Sound of old slot machines
