 Fuel Guage Problem

I just acquired a New Holland model 1925 (used) and the fuel guage does not work. I don't have a trailer to take to tractor to a dealer for service, and was wondering if this is a common problem or if there is an easy way to fix or diagnose the problem. I've already checked the fuses and connected the electric leads to the tank, the guage rises to about 1/4 tank. I'm considering just purchasing the in-tank module to see if that's the problem. Any help anyone can provide would be appreciated.

 Fuel Guage Problem

Look down in the tank and you should be able to see your float. If you need a light... use a flash light and turn it on away from the tank and any fumes. Use some baler wire to reach in and raise the float and see if it registers full that will narrow down your fix. Most likley float is sticking on something in tank and the rod can be bent to one side to clear it.

 Fuel Guage Problem

Harvey's suggestion seems like a pretty good idea. I am finding that the electricals on my mid-80's 1710 were getting a bit shaky. My temp gauge quit, which I got going by jiggling and cleaning terminals. The gauge lights quit which I got going by cleaning fuse holder contacts. My lights quit, which also proved to be dirt on the fuse holder. I think a new maintenance routine 'cleaning the electricals' should be defined at 10-year intervals. If Harvey's suggestion doesn't work, I would make sure the sender unit is getting voltage before buying a new unit.

 Fuel Guage Problem

You can do this by removing the wire from the sender, and with the ignition on,hold this wire to a good ground on the machine. The guage shold rise to the full mark, indicating that the guage and wiring are ok. If it doesn't, try again - you are probably not getting a good ground. The reason I say this is because guages are very reliable. The problem is almost always with the sender - usually the float. They can become saturated with fuel over time and sink, giving a low or no reading. You should be able to get a float and new gasket at your local auto parts store. With this and Harvey's and Tom's suggestions, I think we have it. If not, come on back.

 Fuel Guage Problem

Thanks for all the help and suggestions. Here are the results:

I could never see nor reach the float in the tank so I was not able to actuate the float with it still installed in the tank. I did remove the float assembly and tested the float in a container of diesel. It's bouyancy appeared to be adequate.

I grounded the lead with the ignition on and the guage rose a small fraction (maybe 1/16 full) so in my mind, this test was not conclusive. I then attached a nine volt radio battery to the leads and the guage rose to about 2/3 full.

At this point, I'm thinking the problem is the sender. Any additionl thoughts?

Thanks, Mark

 Fuel Guage Problem

9 volts giving 2/3 gauge would imply 12 volts would give full gauge, so I think you are correct in assuming a bad sender assuming you have verified that all the wiring to/from the sender and gauge are good. I believe most sending units are basically a slide wire resistor. As the float moves, it slides a wiper up and down a resistor providing a variable voltage to the gauge. Most likely the sliding arm of the resistor is either broken, stuck, or dirty. You can determine this with an ohm meter across the connections of the sending unit while moving the float arm. You should see a range from near zero ohms to some max. reading depending on what the total resistance is.

 Fuel Guage Problem

There is something funny going on here - you are getting a higher reading (1/4 full) through the sender than you are going straight to ground. These things work by the sender completing the circuit to ground -you should get a higher reading going straight to ground than through the sender. Does your guage read full with the ignition off? If so, proceed to resistor check as outlined by Bill - gauge is ok. If not uh-well, check the resister out anyway- it's probably the second most likely culprit. If you don't have an ohmmeter, hook the wire back up to the sender, ground the base of the sender with a jumper wire and move the float arm through it's travel. This should show you how the sender is behaving. If it goes to full - looks like we're back to the float or bad ground on sender or tank.

 Fuel Guage Problem

I tried all the suggestions and was never able to fully diagnose the problem. There appears to be some confusion about the results so here is is again. I grounded the sender wire and the guage moved up to about 1/8 tank. When I attached a 9 volt radio battery, the guage moved up to about 2/3 full. So it seems like the guage is working although I'm confused as to why the guage would not read full when I grounded the sender terminals. I'm wondering if I may have a wiring problem. Anyway, I checked with my local dealer and decided to invest the $31.00 for a new sender. If this doesn't work, I'll start investigating the wiring.

Ifo ground the sending unit, the guage should read full.make sure you have a good ground though.If the guage doesn't read full ...the guage is bad....

 Fuel Guage Problem

I don't know where in the circuit the gauge was grounded. My sending unit has two leads going into the tank. I guess the ground lead is brought out of the tank and attached to a ground bus. Jumping the hot lead into the tank should ground the gauge, but grounding the other lead would leave the sending unit in the circuit. If I were using the leads into the tank as a location to ground the gauge, I'd pull apart the connectors to both leads and test with a VOM. The hot lead should show close to battery voltage, which also would be a test for some possible wiring problems.
