With a properly operating alternator, AND electrical system, a voltage output range of 13.5 Volts to 16 Volts is considered acceptable.
Just the alternator puts out around 120 vac, but most newer alternators include a built in rectifier that limits voltage output to between 13.5 and 15.5 volts DC depending on speed.
13.5 to 16 volts.
From the alternator to the battery should be 14v
Output of the alternator is controlled by the voltage regulator.
Put a new alternator on it or tear the old alternator apart and replace the voltage regulator in it.
If you are asking what the normal ouptput voltage of a car's alternator/generator is, it is 13.5-14.5 volts.
change alternator
the alternator voltage at the battery should be between 12.4voltsv-13.6 volts
It's inside the alternator, most people just replace the alternator if it isn't charging but you can take the alternator apart if you know how and put in a new voltage regulator for about $15.
The brake lights come on. The alternator should maintain voltage (14.2) unless the alternator is failing or the battery is nearing end of life.
Voltage flows from the alternator not to it. If it is outputting no voltage it is defective.
the voltage regulater is built into the alternator it regulates how much volts gives to the battery
As little as possible
