New to the site. Any help is greatly appreciated. Just bought a 97 gp760 and the display is not receiving rpm, mph, fuel and oil levels from the machine. Known working display was put in this machine and wouldn't work. Previous owners said it slowly started going out after hitting waves, etc, until it finally quit alltogether. The mode and lockout code work fine, just no feedback as mentioned before. I'm guessing a ground or short somewhere, but have no idea as to what electronics send what or where. Thanks.
