You need to be careful or you will destroy the gauge. There should be a red tag on one of the terminals and that is the one that the sending unit from the tank goes to. The other terminal gets the wire from the ignition. Have you converted to 12 volts?

yes, i have in the process right now , i think it already might be destroyed, because they seem to be hooked up right, as what u said but it was full deflection to full, when the tank was def not full...

if you put an under dash after market. you need to change the sender in tank. if you don't it will read 3/4 when full this is how mine is i'am ok with that when i get below 1/4 tank i know i have extra

If you ground the wire to the sender, it should read "empty".

If you get no movement, then either you have a break in the wire, or a bad gauge.

when they are hooked up the was it supose to be, it reads way past full, and when the ignition switch is turned off goes below empty..... an the tank is not full, maybe a little above empty!!

here is a copy of the trouble shooting guide from fifth avenue antique auto , this was a good how to i used



GAS GAUGE PROBLEMS...
If you understand how a gas gauge is supposed to work, then finding your problem will be much easier. Here is how most (AC) type electric gas gauges work. Two parts make up the fuel gauge system, the dash gauge, and the gas tank sender, located at the gas tank. Power to the dash gauge is received from the "switched" side of the ignition switch which means the dash gauge works ONLY when the ignition switch is in the ON position. There is a small counter weight located on the needle of the gauge which returns the gauge needle to the EMPTY position when the ignition key is in the off position.

With the ignition key in the ON position current flows from the ignition switch thru the small operating coil (located on the back of the dash gauge), on to a "CHOKE" coil. From there the current travels to a common terminal between the two coils. After the current reaches the common terminal between the coils the current travels back thru the operating coils, and then on to ground. At the same time current is also sent to the tank sender where current travels thru the sender unit and on to ground.

When the tank is empty the float will be near the bottom of the tank so most of the current is sent directly to the tank sender where it passes on to ground. As more fuel is placed in the tank the float is raised and more current is sent to the operating coil of the dash gauge causing the needle to move closer to the full mark. It is electrical friction (resistance) from the gas tank sender that guides the current to either the tank sender or the dash gauge.
------------------------- ------------------------- ------------------------- ------------------------- ------------------------- --------
1) The most common cause of fuel gauge trouble is a poor ground especially at the tank sender. Make sure all wiring connections are tight, and free of dirt and corrosion. A poor ground or loose connection to a fuel gauge system is just like loose or dirty battery cables to your starting system.

2) If your gauge needle remains on EMPTY when the ignition key is turned on and gas tank is partially full, battery current is NOT reaching the gauge. Connect a jumper wire between ignition switch and dash gauge. If gauge works, replace defective wiring between switch and gauge.

3) If dash gauge NEEDLE remains in ONE POSITION as ignition switch is turned off and on, either the dash gauge or the tank sender is defective. Ground the gas tank sender terminal using a jumper wire, if dash gauge shows empty, gas tank sender is defective. If the dash gauge needle does not move, replace dash gauge.

4) If dash gauge reads EMPTY or LOWER than it should, check for defective wiring between the dash gauge and the tank sender unit. Also check for poor ground.

5) If dash gauge reads, EMPTY when the tank is actually half full the wiring between the dash gauge and the tank sender is defective or the dash gauge is defective. Disconnect the wire at the gas tank sender terminal, if gauge still reads empty, the dash gauge is defective.

6) If dash gauge reads, FULL when tank is known to be only half full the wiring between the tank or the sender is bad. Ground the gas tank sender terminal using a jumper wire, if the dash gauge still shows full there is bad wiring between the dash gauge and the tank sender. If the dash gauge goes to empty, the gas tank sender is defective.

Here's something else to check.

Half way thru the season my gauge stopped working - it would stay between 1/4 and 1/2 when the ignition was on, even though the tank was full or empty. Grounded at the tank - no change, grounded at gauge - no change. Dropped tank and removed sending unit - bench tested it with ohm meter - worked perfect. Removed gauge from dash and bench tested everything - worked perfect. Put back in car - back to original problem. Took out and bench tested fine again. (It's time to stop and have a beer !!!)

What it ended up being was as I tighted the terminals on the back of the guage, the one stud would twist every so slightly that the tab on the other end that has the fine wire going to one of the coils would ground out and hold the gauge in one position. Moved it back and a little bit of crazy glue later it working great.

Frustrating as hell, but definitely learn how the gauge works !!!

Reading past full indicates there is a "break in the line" between the dash gauge and the sender within the tank. Either find the break or run a temporary new line from the dash to the tank. See what happens ....
