Yamaha F50 trim guage

[Craig Killip]

Dear All,<br /><br />Please could somebody help re. my trim guage?<br /><br />The guage constantly reads 3/4. <br /><br />At the sender unit there are 3? wires going to a plug within the engine cowling. This goes to two green wires which run through to the guage. If I pull the plug on these two the guage does not change. I tried shorting the green wires and still no change.<br /><br />If I take the yellow wire off the back of the guage the needle drops to no reading.<br /><br />Any clues where the fault may lie?<br /><br />Thanks for any help or info.

Looking at it a bit more and searching through the archieves.<br /><br />There are 3 wires coming from the sender. This goes into a two wire plug so only two (green) wires go to the gauge. <br /><br />At the gauge there are again 3 wires.<br /><br />Am I a wire short by any chance? Is this the next thing to try - running a third wire?<br /><br />Many thanks.

I forgot to say that the engine is a 1996 unit and the trim gauge is genuine Yamaha.
