Hamilton credit card acceptor problem

So after the download procedure I noticed that my credit card acceptor was not working.  It seems very easy to trouble shoot on the acw-5.  There are 2 plugs (second picture) on the back of the reader the second plug (red and black wire) should be 5 V DC.  While the top plug (yellow and brown) should be 5 or 8 V DC, of course it was ZERO V DC.  So I need to purchase a new credit card acceptor because Hamilton does not repair the acceptors anymore.  They cost $320 from Hamilton, but I called my buddy Randy Nix at Eagle Car Wash and he treated me right.
