What makes voltage light and fuel light come on and stay on. On my 1995 mazda 929


Hi,if you are talking about the red light for the alternater is on then it means that the car is not charging,and the fuel light is to do with the sender unit in the fuel tank.
to see if the alternater is working ok you need to put a mullty metre on the battery and see what the voltidge is,get some one to press the frotal pedal you should see the reading jump up from 12v to about 14v approx,if the valtidge drops bellow 12v or dose not increase then the alternater is falty replace,
then to check that the fuel sender is working find the wires on the fuel tank take off and join together switch on ignition if the fuel diyal dose not go to full then replace the gauge if it dose go to full replace sender.
hope this was some help,all the best.

Gas gauge won't work and it has a full tank of gas. Is there a fuse I can change.


There might be but it is unlikely a fuel gauge is fused alone; usually if it is a fuse other things will stop working too but I suggest you are guided in this matter by your car handbook.

Problem is probably wiring and in particular the grounding of the fuel tank sender unit. It could be a faulty sender but they are usually quite reliable.

Test by disconnecting the wire from the sender unit at the fuel tank and short to a good ground and the gauge should read full. If the gauge wire is in a block with other wires it will be necessary to positively identify the gauge wire before testing.
If the gauge reads refit the wire and duplicate the ground wire to a known good ground. If the gauge still reads the fault is a bad ground to the tank sender unit and if it doesn't the sender unit itself is probably faulty.

If grounding the gauge wire does not produce a reading the fault is the wiring to the tank, the supply to the gauge or a problem with the gauge itself.

I have a 1992 Mercury Grand Marquis Ls with a fuel gauge that does not work (gauge may be reversed)??? help please.


The fuel level indicating system is a magnetic type system, which consists of the sending unit located in the fuel tank, an anti-slosh module located on the back of the instrument cluster, and a fuel gauge located in the instrument cluster. The sending unit changes resistance according to the level of fuel in the fuel tank, which varies the current flow through the gauge.The pointer position varies proportionately to the current flow. In this system, the sending unit resistance is low (22 ohms) when the fuel level is low and high( 145 ohms) when the fuel level is high. The pointer of the magnetic gauge remains in position when the ignition is turned to the Off position. On some models, an anti-slosh module is used to dampen out fluctuating fuel signals from the sender. Some vehicles are equipped with a low fuel warning indicator. The anti-slosh module will also actuate the low fuel indicator when the fuel level in the tank reaches 1/16 to 1/8 full.


Do your other gauges/warning indicators work properly with the ignition on? If not, check for power at the fuse panel/fuses.

If they do then partially remove your cluster with connector still installed and check for voltage at cluster connector and gauge. Check continuity of cluster and gauge for ground.

Sometimes the anti-slosh module (if installed) goes bad in the Grand Marquis but not likely.

Sender troubleshooting:
  1. Perform test with resistors as follows:
    1. Disconnect wiring connector at sender unit, then connect resistor between gauge lead and a suitable ground.
    2. Turn ignition switch to On position.
    3. With 145 ohm resistor, the gauge pointer should contact the Full mark.
    4. With 22 ohm resistor, the gauge pointer should contact the Empty mark.
  1. Perform test with fuel sender of known quality as follows:
    1. Turn ignition to Off position.
    2. Disconnect wiring connector from sender and connect it to test sender.
    3. Move float rod away from fuel filter against Full stop position. Wait approximately 30 seconds, then turn ignition switch to On position. The gauge should read on or above the Full mark.
    4. Move float rod toward fuel filter against Empty stop position. Turn ignition switch to Off position. Wait approximately 30 seconds, then turn ignition switch to On position. The gauge should read on or below the Empty mark. If gauge works properly replace sender, which involves dropping fuel tank.

Fairlane faulty fuel gauge


ford have a gauge sender in the tank that operates by a resistance through the fuel. less fuel more resistance lower reading. I would check for voltage at the tank unit and it is more than likely the fault will be found in the sender unit

Fuel gauge alwaya read full


The wire between the dash and the fuel tank is connected to ground somewhere. there is a control that fails too but if the control failed the temperture gauge also won't work. The wire can get in troble inside the tank too as if someone tried to steal the gas with a hose. if you can disconnect the connector ( wireing ) at the fuel tank and turn the key on and the gauge goes to empty you know the troble is inside the tank and the pump sender unit will need to be removed from the tank to correct the problem or even the gauge unit replaced.70198425.jpg

Check the wires to the senders for grounding Those gauges have a power lead to gauge then to sender. The more the sending unit "grounds" the higher the gauge reading

2000 Buick Century gas gauge reads full all the time


You're either looking at a short in the wire that goes to the fuel sender, or a bad fuel sender. If it was just a broken wire, it would read empty instead. The fuel sender is a permanent part of the fuel pump, so that has to be replaced as a unit.

Fuel gauge reading zero and light on ?


Ford has lots of problems with the sender reliability. Typically, the sender (and expensive fuel pump) replacement resolves the issue. To test, you need to take the connection off of the sending unit, at the tank, turn on ignition, and then ground and un ground it and view results at the gauge. If the gauge responds, the sender needs to be replaced.

There are aftermarket senders that cost less than OEM.
