On vehicles with a 12 Volt electrical system the alternator [or generator if so equipped] output voltage is considered acceptable if it is in the range of 13.5 volts to 16 volts.
Any voltage below 13.5 volts will not adequately recharge the battery, and anything above 16 volts will tend to cause the battery to overheat, and boil-off the water from the battery.

What is the voltage of a car alternator and is it ac or DC?
It should produce 14.5v +/- and it's DC.
How do you know when you have a bad alternator?
it will not produce voltage or high enough voltage when running should be around 14 volts running
What kind of voltage does alternator produce?
dc
Why connect capacitor to alternator?
To help produce voltage.
How much voltage does an alternator produce?
13.5 to 15.5 volts.
Does an alternator produce a c voltage?
Yes, and internal diodes convert it into dc.
How much voltage the alternator of Skoda octavia gives?
the alternator voltage at the battery should be between 12.4voltsv-13.6 volts
S10 blazer reads high voltage?
The s10 uses an alternator and regulator to produce voltage. A high voltage is most likely caused by a faulty voltage regulator.
Where is the voltage regulator on a 1998 Lincoln continental?
it should have the voltage regulator built into the alternator
How much voltage does an Isuzu trooper Alternator produce?
Alternators should produce around 14 volts. I say around because this can vary with temperature, engine speed and the age of the alternator. If you think yours is kicking out too much it's probably the voltage regulator. If you think its not enough it could be the brushes. The easiest thing to do is to pull it and take it to a parts store; most of them will test your alternator for free.
Should you jumpstart a harley?
No ..well you can but if battery is bad then the engine will shut off when you remove the jumper cables because of the way that H-D has their regulator /alternator wired you must have battery voltage to tickle the alternator to produce voltage, if battery is simply "low" then you might be sucessful.
Can a car's alternator charge the battery while the car is not running?
No. The alternator has to be turning to produce the charging voltage. It only turns when the engine is running.
