Got another... Patient is a 200 Yamaha

The trim display on the gauge stays on one "bar" regardless on the engine's actual trim. I checked the sender on the left side of engine mounting bracket and the little arm moves freely with smooth resistance.... Any clues where to look without breaking out the ohmmeter? Do the senders themselves fail?

The actual gauge works fine otherwise.... Its fuel tank level even correspondes the the mechanichal gauge on the tank!

Regards, Ed

if its one of those multi-meter lcds you better break out the voa and test the sender. hope that its the sender, the guage is hard to come by and new its exorbitant. steve out.

Just had this problem on my new Yamaha 90 that was installed. The trick was to get the settings on the back of the tach correct. There is a little rubber button that comes off and gives you access to three little, and I mean teeny weenie, DIP switches. Mine was not set on the factory setting, which should have been for a two wire sender and thus it was just as you describe - no reading. I flipped the switch and everything operated ok. The correct setting are on a little green card attached to the tach wires, but frankly all you have to do is change the setting on the leftmost switch and see if that helps - there are only two positions. The other two switches are for other things, I cannot remember exactly what - alt typ and 2/4 stroke I think. Let me know if you need more help.
