There should be a wire that connects to the gas tank sending unit and maybe another wire connected to a spade terminal that could be screwed down to the in-tank sending unit. The brown wire from your gas tank sending unit goes to the back of the dash guage. All the gas tank sending unit does is give a "ground" signal to the dash guage. Whatever you do, do not connect the brown wire to a positive 12 volt wire as sending 12 volts through the gas tank sender will explode the gas tank! Take a look at this website and it will all clear up for you.

You did not say if your dash guage is wires with a plug-in or single wires connecting it. If what i've given you here is not enough to fix the whole problem then respond back with how does the wires connect to the back of the guage. Good Luck!

Wiring a selonoid


http://www.ntractorclub.com/

The link above is just one of a dozen or more very helpful websites for Ford 8n tractors.
The original 8n tractor had a six volt battery with positive ground (this is different than most automobiles that have a negative ground). The starter solenoid is energized via the ignition switch and the large starter button in front of the gear shift, the small wires going to the solenoid energize a coil which "pulls in" and completes a circuit that then provides 6 volts directly to the starter motor through a large, heavy gauge wire. The smaller wires connect to the two terminals on the top of the solenoid and the heavy wire goes to the larger post on the solenoid and originates from the negative post of the battery... Hope this helps. There are many, many schematics and pictures available on the "net" The Ford 8n community is very large and extremely helpful....Good Luck

Why does my 8N Ford tractor die at about half throttle?


Sounds like it might be starved for either air or fuel. Have you made sure there is full gas flow from the tank to the carb? Also recheck the needle valve regulating gas flow into the carb. May be that a speck of trash is partially plugging that flow to carb. Should have in-line fuel filter (add on) in addition to the bowl 'filter

Ford 8N will not start when hot


This sounds like a bad fuel pump to me. The only way to be sure is to check the fuel pressure when cold, probably around 45 PSI. Then when it get hot it will drop way down to 10 or 15 PSI. Check the pressure if you can, or change the fuel pump.

Need a good website to go to, to buy parts for a 1972 Chevrolet Pickup w/ a 454 in it. Besides LMC Magazine.


autopartswarehouse.com and autozone.com are some of the better/cheapest sites. Both sites have excellent OEM replacements. LMC has a great selection but slighlty overpriced but if you can't find what your looking for, LMC should have it. Good Luck.22

Fuel guage problem


CHECK THE SENDING UNIT FROM THE FUEL TANK. GET A "D" CELL BATTERY AND CONNECT THE WIRES FROM THE SENDING UNIT DOWN BY THE FUEL TANK. ONE WIRE TO THE POSITIVE END AND THE OTHER TO THE NEGATIVE END OF THE BATTERY. HAVE SOMEONE IN THE CAB VERIFY THAT THE FUEL GAGE MOVES. IF IT DOES THEN YOUR SENDING UNIT IN THE FUEL TANK NEEDS TO BE REPLACED. THIS IS A VERY COMMON PROBLEM AND AN EASY FIX.
