Fuel Mgmt system on twin 250 yamaha's

[contender]

I am having a problem with the port side readout. I replaced the sending unit on the port side and still no read out. The gauge goes through the start up sequence so i think the gauge is working properly. When I hit mode on the gauge it goes thru the 3 functions. When I hit set nothing happens. Is there any test I can perform to resolve this matter? Thanks

i would try swapping senders/harnesses to diagnse issue.

I'm having the same Issue. I believe my Starboard transducer is bad. I ohm checked it and it read 34 ohms, across any of the 3 wires Port side was open, and is working. I'll let you know if it fixes it.

Ive experienced this also now on my system, disappearing and reappearing P or S....forget which one, but now getting no reading so im assuming its clogged again, so i will break down the sensor and unclog.
