Check the voltage with the engine running. If it is 14.5 to 12 it's the guage. 14.5 and above it's the regulator.

Just replaced my alternator on my 2000 dodge dakota sport. jump started truck, while driving my voltage gauge jumped to over 18, had to turn on headlights and heater @max to get guage to decrease to...

the amperage of the alternator is immaterial as long as it is big enough to run the electrics of the vehicle
what is indicated here is that the new alternator required an external voltage regulator or a properly operating regulator to regulate the output voltage
battery voltage in a new battery fully charged is 13.2 volts dc and when the voltage regulator is working the controlled voltage is 14.5-14.8 volts dc
check how you wired up the alternator and have an accredited to test the charging circuit

I have a 2001 chevy impala my tempature gauge completely quit working 2 days ago and my gas gauge is all over the place i dont know if its full or empty.. most of the time it stays at half or a little...

It sounds like the voltage regulator for the insturment cluster is malfunctioning -- that's why you got the recommendation to replace the instrument cluster.

If it were just the temp guage failing, the problem could be a faulty temp sending unit in the engine block. However, with more than one guage failing, it sounds more like an insturment-voltage- regulator problem.

An instrument cluster would contain the voltage regulator.

It's possible that the voltage regulator cold be repaired and an entire cluster would not be needed.

More info, please let me know.

Need to find out why the radio, guages, and speedometer all just quit, have checked all fuses. Did troublshooting online and it tells me it could be the voltage regulator or the engine temp sensor. I dont...

Start with verifying that the fuses are indeed GETTING power to them and they are indeed good. Use a test light to check fuses. When the engine is running, gently turn the ignition key either way and see if they come to life, if so, the ignition switch is bad. The Voltage Regulator or Temp sensor have absolutely NOTHING to do with your problem.

My 03 x type jag wont even try to turn over? Dash lights are fine but windows, mirrors and starter dead! All the dash lights and monitor and radio work but wont even tryto start? Transmittion wont come out...

Sounds like all of the high drain devices are disabled due to a weak battery. You are still getting dash lights and radio because they are very low drain devices. Try charging the battery to test for now. It could be a failing battery, or your alternator and or voltage regulator could be going out and not charging the system. But first, try to charge the battery, and see if you can start it, if you can, let it run for at least 10 minutes. If your alternator/VR is going out or is already out, you should have a guage, or idiot light telling you that you have low voltage. If its a light, you should see a red battery lit up on the dash, if its a guage, it should be directly in the middle +/- a little. If you are able to run the vehicle for a while with no light coming on, or guage showing low voltage, its safe to say you drained the battery, or it is failing. If its a few years old or more, i'd go ahead and replace it. Hope this helps :)

the alt variation is normal. When under load or not under load, the amps will fluctuate. If anything else, the voltage regulator is faulty. Or, there is a faulty relay somwhere

Battery indicator light on.

Check the alternator at the battery terminal with a voltage guage and engine running. At the battery terminal with engine OFF voltage should be at least 12volts with engine running it should be at least 14volts. If it Not 14 volts with engine running then the alternator is UNDER charging and will trigger the light on the dash. Good luck and thanks for using FIX YA.

Fuel and Temperature Guages

Have your alternator output checked; the voltage regulator might be failing.
You can check it easily across the battery terminals.
You shouldn't have any more than ~ 14.3 volts at any revs., and about 12.6 with the engine off.

If it checks out OK, the next step would be to access any plugs to the instrument panel, pull the connectors apart and then replug them.
You may have a flaky ground under the dash too.
