I have 6 Unitec Wash Select II paystations. All have the IDX multi coin acceptors. They are constantly losing their memory, breaking or something going wrong with them. They are junk! Has any one changed these to a different multi coin unit? I tried putting in a Micro Coin QL acceptor but that unit only has a 4 wire hook up and the IDX has 6. Could'nt figure out how to make it work. I welcome any insight to making it work or what acceptor to change to that is reliable. We accept quarters, dollar coins and tokens so it has to be multi coin.
