How to test fuel level sensor on 3206?

Joelk · Mar 21, 2016

I just got a 3206 that seems to be in pretty good shape.

I have done a good bit of disassembly and cleaning and noticed that someone has removed the bulb to the low fuel gauge.

I pulled the tank to clean out that area and thought before I put it back together that I would test the fuel sensor.

I checked for resistance and it shows continuity with the float up or down.

How would I determine it it is functioning properly before I install it back in the tank and reassemble the tractor?

The ohms should be from around 0 to 240 or 270 if I remember right.

Those fuel sensors are failure prone. I had my 3235 for 11 years and replaced the original sensor when the low fuel light stayed on all the time and then the new one failed several years later. It should show continuity when upright and open when inverted. If I remember a replacement ran about $27.

Good luck on your 3206. I bought a 3235 last summer and my fuel sensor does not work either. I intended to repair it this winter but it didn't happen. Can you change the sensor by removing the seat assembly or do you have to remove the rear fenders?

I replaced the sensor on my 3235 by removing the seat. Make sure the fuel level is low enough before pulling out the sensor. There is a rubber grommet in the tank opening that should also be replaced. You may have to wiggle the sensor around a bit to get it through the frame opening under the seat. Mine only lasted a few years before failing again. I notice that they eliminated the sensor on my new Enduro GSX.
