Install New Credit Card Reader!

I installed a new Hamilton credit card reader (acw-5) today and that reader did not work either.  I called Hamilton tech support and they said it was a bad card reader.  Later I noticed that when either card reader was outside of the housing the reader would work.  Randy Nix of Eagle Car Wash told me there must be a ground issue and he was going to talk to a Hamilton tech tomorrow.
