gauge malfunction

[Jimmyrowe]

I have a 2013 Ranger Tug R25sc. The digital gauges show up on the screen but there are no readings. A new electronic control module was installed, but that did not solve the problem. It is a 150hp Yanmar. Any suggestions?

Do you get engine information on your Garmin? This is out of my expertise, but it sounds like (hopefully) a corroded connection. I ask if you are getting the info on the Garmin, because that would indicate that the info from the ECU is talking. I would start by checking all your connections at the engine compartment. You should have a wire diagram showing where the wires from the display connect. I never was happy about how they had all the wires connected under the gutter on the port side. I wrapped mine in a plastic bag and sealed it as best I could.
