Coin acceptor problem – again

I got a call last night saying the bay was stealing money again.  When I got to the wash the wire harness was out.

I plugged the timer back in and still got the "COIN" error on the timer.  I swapped the loop detector and still got the same error.  I unplugged the loop detector and still got the error message.  I unplugged the coin acceptor and the loop detector are still got the same error massage. 

I talked to Greg and he thinks that there has to be a short in the wires.  I will have to check tomorrow.
