    An easy start to the process of elimination is to check the condition of the main wiring harness plug-in connections. All your wires leaving the engine normally run through this plug.

    Good Luck

      Look for green gunk on the connectors.

        +1 on that.. if that does not do the trick then you should check the sending units that are on the engines. I just replaced all of mine, fuel, Tac, Engine temp and oil pressure.. All gauges work now. The sending units go with the gauges, you probably have Faria gauges, you can Google Faria and find there website. Call there and talk with Jason Clarke X1229.. Tell him you have Diesel's and need the correct sending units, he will give you the model numbers which you can Google to find the best price.

        Your tac sender is probably this unit:

        http://www.shipstore.com/SS/HTML/FAR/FAR90901.html

        $53 is pretty high I think mine was around $42 so shop around...

        Hope this helps.

            Try http://baylinerownersclub.org/galler...2_itemId=40738 for info on the electrical things. It's from the Hino shop manual.

            The manual is a little hard to follow but the info is all there. I had to read it a number of times before it made sense.

              Sounds like you have the "star wars' gauges. Can you take a picture of them and post it? The more info the more people can help.

                  They were just branded by US Marine but made by someone else. Look on the back and along the sides for a Paten #, you should be able to see the maker's name; most likely Faria. I do not know where the senders are located on your engine but mine were pretty easy to find. Get the part numbers from Faria, Google the part numbers and look at the pictures. Then go to your engines and find them. They will have wire and ring terminals attached. do what the earlier post suggests and clean the terminals, etc first.. that may fix your problem. If it does not, then order and change out your senders
