Most alternators should put out between 14-14.5 volts, and this would be the reading if you have everything else turned off in your car (no Air conditioning, no radio, etc.)If they get too much over that they can damage the battery causing it to literally explode.

What is battery volts high?
Alternator is sending to much volts to battery. Suppose to turn itself off when battery gets to around 13 volts. May need new alternator.
Why would an new alternator on a 2004 Chevy Venture randomly put out 18 volts?
The new alternator probably has a faulty voltage regulator.

My volts meter on the dash does not stay at 13 volts new battery put in new post terminals?
Have your alternator tested it sounds like it is not charging.
Why would a car with a new battery not start and once you give the battery a jump it starts it's a 1999 Mercedes c230?
probably has a bad alternator. With the car running use a digital multimeter an you should have 13 + volts (as high as 14.5+) at the battery terminals if the alternator is working. If only 12 volts or so then check the alternator.
How do know when to get a new alternator?
If it is not keeping the battery charged then it is defective. Start the engine and connect a volt meter set on 20 Volts DC to the battery posts. Red probe to positive and black to negative. You should get a reading of from 13.5 to 16 volts. Any less or more and the alternator is defective.
If a 1981 Lincoln Town Car is getting 10 plus volts to the distributor but no amps what could cause this?
i think you should try a new alternator buddy. u shold be getting 14+ volts maybe that will work :)
Is it OK to drive a van with a new battery if the alternator should test 1340 but tested 1270?
The numbers you referenced seem as though they may be specific to an individual tester, unless you're talking about 13.40 volts vs 12.70 volts. If the alternator is only producing 12.70 volts, you'll probably run the battery down. How did you come up with those numbers?
I recently installed a new stereo system into my car now my car sounds like my battery is weak is it my battery that I have to change or my alternator?
Check the battery with a vom meter while the engine is running. It should read about 14.5 volts and if so the alternator is working, than have the battery checked Now if the meter does not read 14.5 volts, have the battery, and the alternator checked. If they both check out okay, the problem is in the battery or the alternator circuit on the vehicle.
Why is your 1985 Corvette voltage light on?
check charging system voltage it should have 13.8 ---14.3 volts it alsocould be a bad diode in your alternator most times a new alt does the trick
Why is the battery light on in my 93 Crown Victoria It has a new battery and a new alternator.?
Since you replaced the battery and alternator, you must have had a problem before. Did you run a voltmeter on the battery while the engine is running? Should have around 14 volts. If you are getting around 14 volts, you can assume that the lite might be faulty. If you are getting say, 12 to 13 volts, then the alternator might be faulty, yes even sometimes rebuilt ones. Check all the wires to make sure there is good contact, also if you still have the problem, then you might have a broken wire ( somewhere ). Good luck
Car only starts when jumped with another car and my battery is new so is the alternator what else could it be?
Don't depend on "new". A new part can also fail and they can be faulty right out of the box.Find a voltmeter and test the battery. It should be around 12 Volts, maybe a little above. Then start the engine (using a jumpstart if necessary).With YOUR car only running on the battery, use the voltmeter again to test the voltage. If the alternator is working you should have about 13.5 Volts. If it's much below that the alternator isn't working. If that's the case, make sure it's connected properly before you try to replace it.
