What voltage battery are you referring to? An automobile battery is 12 volts and a fully charged auto battery should read 12.6 volts.

How do you know when an alternator is going bad?
Battery fails to charge, alt light comes on, sometimes only at low revs. Check with meter shows low or no charging voltage (close to or less than battery voltage) voltage does not increase to charging volts with engine revs increase
If the ignition is off and the Battery shows 11.5 volts when the engine is running shows 13.6 Volts?
It shows that your battery is in workable condition and your alternator is charging as it should.
Why wont my Honda magna v45 hold its battery charge after riding?
Two possibles. Either the battery needs to be replaced, or the stator is not charging. First check the battery with the engine off, should have 12. 2 volts or more, if under 12 volts, then charge and check again. If under 12 volts, then replace. If over 12 volts, run engine, check the battery volts, should have over 13 volts at idle, rev up, should get over 14 volts. If battery still shows only 12. 2 or so volts, then the stator in the engine has to be replaced.
What is the correct voltage wile older car is running ohms meeter shows 14.35 volts?
Voltage Output Range for Automotive Charging SystemsThat is correct voltage. Additional InfoA charging system output voltage which falls anywhere within the range of 13.5 Volts to 16 Volts is considered acceptable.
Your volt meter shows your generator is producing 145 volts will it damage your electrical equipment?
Yes it coudl damage equipment. Check voltage rating on equipment. However, there should be an adjustment somewhere on the generator to set the voltage properly. Also make sure your meter is calibrated. Check a known voltage source such as an outlet and compare readings.
Voltage regulator test?
Hook up a voltmeter to the battery terminals and start the vehicle with nothing on. You should get a reading from 13.50 to 15.0 volts. Perfect setting is 14.2. A higher reading tends to overcharge the battery and a lower setting doesn't charge the battery fully. Turn a fair amount of stuff on (headlights and heater, etc.) speed the engine up and see if voltage remains between 13.5 and 15.0 volts. This shows that the alternator is keeping up with demand and alternator is working good.
How do you identify battery terminals without any marking?
Best way would probably be to use a multimeter or voltmeter. Turn the meter on to volts DC and connect the probes to the battery terminals, if the voltage is shown as a negative, then switch the meter's probes around at the battery end so it shows the voltage as a positive reading on the meter. Mark the positive and negative terminals on the battery after this. Some car batteries have the negative terminal as the small post, but on some as the big post.
Your 98 durango turns over but does not start you have no spark the fuel pump runs constantly the auto shut off relay for the fuel pump ticks rapidlyand scan tool shows 5 volts as does the volt gauge?
Going off what you've said I would guess that you need a new battery. 5 volts is very low and not enough to provide a strong spark. You need to test your battery properly. Turn the car off completely and test the voltage of the battery between the positive and negative terminals. You should have about 12 volts. Then, keeping the tester in position, turn the ignition to start for 5-10 seconds. The battery voltage shouldn't drop below 10 volts. Anything below 8 and it is completely shagged.
What can be wrong if the car does not start but the battery light shows.?
Among other things; Just because a battery has approximately 12 volts does not mean it is good. It can produce those 12 volts but without the amperage available from a good battery, you will get nothing. defective plates in the battery will allow it to generate 12 volts while severely reducing the available "cranking amps". Quickest way to rule out a battery is with a jump start.
When bad battery cause dc car voltage ok. cause ac volt on car running show what ac volt is ok?
Vehicles run DC. 13.5 - 14+ volts at battery is o/k. Shows alternator is charging but won't tell you amp output. If the battery is bad you will wear out the alternator as it trys to keep a bad battery charged (it will work itself to death)
How do you check your charging system on a 95 aurora?
I take usually it to O'Reilly or Autozone and they do it for free. If my car won't move, I have a battery/alternator tester (which only shows if the alternator is putting out a good amount of voltage/amps).
The battery light came on on your 91 Previa while on a trip I drove 133 miles before stopping I checked the battery it shows 11 volts you pull the plus cable off the engine dies is the alt bad?
yes more than likely check the alternator belt first do
