I have a 2006 B7610 which has been outside for a few years. The full gauge automatically goes to FULL when you turn on the key and stays there. Any ideas?
B7610 Fuel Gauge stays on FULL

Either the float is mechanically stuck at full ( rust ??)
or
sensor wire is shorted to ground.
Easy test...remove sensor wire then turn key on..
meter should read zero.
if it does, then pull sensor out of tank, inspect and test.

Yup, either the float is stuck or you got a short in the wires. Could be corrosion in the quick connect in the wiring harness.
Sending unit measures resistance on the float. As the float raises it shows a greater resistance.
Easy way to tell if it's the wiring or the float is to disconnect the fuel sending unit.
If gauge reads empty, then the issue is in your float attached to the sending unit or the sending unit. Either the float is stuck in the full position or the sending units bad. It's all one piece.
If the gauge remains showing full, there's an issue in the wiring.

Thanks to both of you for a quick response. this is what I suspected just wasn't sure how to test it.
Best I could find was the service manual take off hood, dash and cowling to get to top off tank. I haven't done it yet

curious, so I looked at the parts online...
first I'd disconnecet battery (just to be safe....)
one screw (top,front)to 'loosen' the dash
few to remove the 'side cowls'...
2 bolts from below to remove 'cowling' covering the tank...
course it couldn't be THAT easy..... but it 'looks' simple enough......
I copy,save and print the online parts drawings as I need them
saves trying to remember things and trips to computer....

I'm sure something will cause a headache. I already see on the b7610 the throttle lever and maybe the steering wheel will have to come of to remove the lower dash panel which looks like it is hooked into the cowling. I'll post back when I'm done but it maybe a few days, have a job to finish first and better to keep the tractor working as is

I guess I'm old school when it comes to fuel level. The Guage is nice to have.
But I was taught to fill a diesel back up when you were done for the day.
So I always knew I had a full tank of fuel when I went out to start my tractor.
I also had it figured out how long I could run in a day before having to fill it back up.

Sorry it took so long to get back on this. Finally had enough down time to fix the B7610, hardest part was getting cowling loose enought to get to the top of the tank. I did have to remove the throttle handle but didn't have to remove the steering wheel. Gauge is working now. Thanks to everyone who commented.
