First the gas gauge issue which just happened. I added 60 gallons and my gauge was still locked on about 1/4 full. Turned off the key a few times to reset all gauges and no change. I then reset all the pop up fuses inside the center console with ignition off but battery power switch on and the gas gauge resets to what seems about right (nearly full). I do not know what circuit the gas gauge is on. A simple sight inspection of the sending unit on top of the tanks looks ok. Is the tank sending unit the common issue? Or my Yamaha gauge or ? The 2 stroke tank gauge has always shown full on my Yamaha gauge so I replaced the tank's sending unit with a new Yamaha part and it still shows full all the time. Testing needed...
It must be the summer of gauges for me...and I like to know the GAS gauge really works.
These are both Yamaha OEM gauges and I assume they both have power since they are correctly displaying numerous other things: the left gauge shows fuel (in a vertical display) and the right gauge is 2 stroke oil level (uses a horizontal display near bottom of gauge). I looked up some testing processes for gauges and will give them a go this week as time allows. Any insight is welcome. I just pulled the wiring diagram on this site.

I’d think the sending unit to be the most likely failure point, but how to test, no idea.

Can't help you since mine doesn't have an oil gauge. Only has a low oil alarm. My last 200 hpdi didn't have one either with OEM Yamaha gauges, far as I can remember.
