2009 cub cadet ex3200
I'm new to the forum, so hope I get this correct.

I just purchased a 2009 Cub Cadet Yanmar EX3200 tractor and my fuel gauge and Temp gauge are dead. All warning lights, tach, hour meter, headlights and dash lights work perfect. Any help or ideas? Thank you

Thanks, I did check all fuses and they're good. Each gauge has 3 wires on back of them, red, black, yellow. With a test light bought gauges red wire has power.

I'm sure you have probably checked the sensors making sure the wires are connected to them?

yes sir, even tried grounding the positive wire on the fuel sending unit. Nothing happened with the needle on the gauge. I haven't pulled the sending unit from the tank.

Do you have a wiring diagram? I am wondering if one of the 3 wires going to the gauges is for illumination?

I bet the yellow one is lights, I'll check it.

I would guess yellow is ground, black and red hot. Sure nuff a guess.

Fuel gauge worked a couple days off and on, but not the temp. Could it be a ground?

Short answer, but yes it could be ground.
