fuel gauge

[Chief 83]

If there are 50 guys out there with fuel gauge problems, mine are worse! I've rebuilt motors, painted tractors and cars, rebuilt fire pumps you name it. I've never had so much trouble as making fuel gauges work. My latest issue. New sending unit and new gauge. No matter what I do with this one if the sender is supposed to be showing full, it shows 1/4 and goes down from there. Can't make it go to "full" on the gauge. Checked ground (actually added a second one)and have 12v to the proper side of the gauge. Gauge is grounded directly to the battery. Could it be that the sender and the gauge are different ohms? I really don't know what that means or how to check it but I've heard of that as an issue. Sender and gauge came from different sources. I think I will try a universal sender that a friend of mine has and see if that makes any difference. Otherwise I'm ready to cut a dip stick and give up on this one....

Without being there a seeing the parts I would say wrong sender or you need to adjust sender

I assume this is a JD. Without knowing more I strongly suggest you get the gauge and sender called out for this tractor and follow the wiring. My experience so far is there is no such thing as "universal". I've dealt with 2510, 2520, 3010, 4020 24v to 12v conversion. Without drawing out each circuit it seems all have differences. Someday I will do that. In the mean time I just make sure I have the correct parts and add a dedicated ground wire from the sender to the gauge (or gauge case, depends on how tractor and gauge is wired.). I also dry run the complete circuit on the bench, then install it.

I do not believe there is a universal standard, but am happy to hear if someone does. I do know that deere had a lot of different ones with the combinations of 6V, 12V and 24V.

Well - I bought a Ford truck, and the previous owner had installed a Chevy sending unit. Hard left empty on the gauge is actually a full tank of fuel. It runs over to register "full" long before it gets empty. There's no "fixing" it, unless I replace the Chevy sender with the correct Ford unit. I check it with a calibrated stick if I really wonder how much fuel it has. I also check my tractors with a calibrated hammer handle, so it seems natural to me. No big deal for low mileage farm vehicles.

Is the fuel tank grounded as well as the gauge? What happens if you pull the sender out of the tank and wire it to gauge and operate it manuely?

Try calling Evergreen Restoration they work on a lot of fuel gauges. 715-635-8629. Hope this helps.

There were no 24V fuel guages.
