Fuel gauge not working


You will need to test a number of things, the fuel gauge is part of a rather simple circuit.

Battery -> gauge -> tank sensor -> chassis ground to battery

If the circuit is broken at any of the steps, your gauge will read "empty". If the tank sensor is bad, it could read empty, or if the float in the tank has sunk, it will read empty.

I start at the gauge with a "test light" that glows when it sees battery voltage. Get a light at the connection to the gauge? Good. find the sensor connection, usually on top of the tank, accessible in the trunk. Probe with test light. Light on? Good. Connect wire to ground, gauge should read "full". If all that is as I said, then the tank sensor is bad. If you don't read battery at any step, you know where the problem is.

Battery gauge low..changed battery already?


Voltage should be about 14v while running.

03 Saturn Gas Gauge reading wrong fuel amount


You need to check the voltage supply to the fuel gauge. If it is the same as the battery voltage the instrument voltage regulator has probably failed.

Instruments require a stable voltage that is substantially lower than battery voltage and this is provided by a small voltage regulator, usually found mounted on the printed circuit of the instrument panel.

My battery keeps dieing while running. just changed the alternater three weeks ago.


Hi.

Make sure that you also replaced the battery. Battery elements may be shorted inside. That will result in battery draining even if the alternator is working.

If you have already replaced the battery check power across battery terminals with engine on and revving above idle.You should read voltage in a range of 13.5/14.4 volts when engine is revving at about 2K rpm.

If the voltage is still wrong after replacing alternator and battery check the voltage regulator connected to the alternator. Here the part.

If battery, alternator and power regulator are OK, test wiring to find out if there is a short to ground that is draining the battery while you drive. This fault is quite unusual with your symptoms. Check battery, alternator and voltage regulator first.

Regards.

The gauge needle goes up to 3/4 of the way, have already replaced the thermostat....


If you are talking about the temp gauge, this could be due to an airlock in the cooling system, a blocked radiator, a work water pump or even a faulty gauge. You may also find that the voltage regulator (inside the instrument cluster) is faulty and giving a higher voltage to the gauges then required. This can also cause the gauge to read higher then normal.
Have these items checked by a qualified person.

I HAVE A 2003 TRAILBLAZER IM HAVING TROUBLE WITH THE CHARGING SYSTEM,I CHANGE THE ALTERNATOR BUT IT STILL SHOW THE BATTERY GAUGE LOW CHARGE NEED HELP ON WHAT TO DO


You need to check the voltage at the battery itself, if the battery voltage is indicating in the area of 12.5 - 14.0 volts and your dash gauge does not agree, then the dash cluster has a bad stepper motor which drives the gauge.
If the battery voltage agrees with the dash gauge, and the alternator was changed and is assumed good, you need to check the wires going to the alternator, there may a broken connection.

Speedometer, tack, fuel gauge, temp gauge have erattic behavior


With Ign. off what is your batt.voltage reading than take neg. cable off and take another reading 5 min. later. It sounds like a intermitten short, try to isolate voltage drop when acting up. Gauge circuit would be a good start. Schematic would be helpful.

Voltage gauge reads low end of normal and moves up to high normal


replace the battery and check voltage regulator
