yep, it is me again. I have a 1988 sundancer 340; I changed my dash pannel today, and now my sync guage is not working. I must of wrote the wires down incorrectly. Does anyone know where I can get a wiring diagram for the dash? It is not in the owners book. Once agin thanks in advance.
If it wasnt for beer, I would sell my boat!

Such a thing does not commonly exist.

Often, if the mfgr adheres to the relevant ABYC code, then the ABYC color coding should keep you out of trouble. Sometimes a mfgr will print and deliver the "typical" diagram for that series of boats ( note: this -might- match your boat. Maybe not... )

Before you panic, maybe you got it right but messed up the grounds... check them first. And perhaps others can lead you to the ABYC color code chart.


FWIW: None of the "typical" diagrams that came with my boat matched my boat. I made my own. Some grumbling was involved.

Doug- I don't know the correct wiring for the synch ( though I'd suspect the tach feeds from each engine would have to be gray wires), but a quick Google search turned up an ebay-express listing (#280160280813) for 2 brand new old stock SeaRay synch gauges. If you were to contact the seller , perhaps you could get him/her to send you a copy of the wirng diagram?

Most boat builders use the standard engine builders wiring harness for the helm wiring. Thank goodness there is a standard marine wire color code, makes it easy. For a typical Mercruiser helm wiring diagram, download this:

For a typical synchronizer, try this.

The RMP wiring may be off as well I looked at it today and the purple wire went to the sender screw. The diagram should help when I get back to the boat. I will get back to you. . . but in the mean time if anyone has a full dash wiring diagram let me know. Thanks
