Generally, an automotive alternator is considered to be "good" if the output voltage is in the range between 12 1/2 volts and a maximum of 16 volts.
Anything below 12 1/2 volts probably will not adequately charge the battery, and voltages above 16 volts can "cook" the water out of the electrolyte, and cause damage to the battery.
What else can I help you with?
How much voltage is a 1998 DOHC 4-Cyl 2.0L Plymouth Neon supposed to produce normally?
The alternator output should fall between 13.5 to 14.5 volts.The alternator output should fall between 13.5 to 14.5 volts.
What is the voltage of an alternator of a 1999 Daewoo Nubira?
on any 12v car, the alternator output should be between 13.6v to 14.4.
How does an alternator know how much voltage output?
Output of the alternator is controlled by the voltage regulator.
How do you get a battery light to go out in my 1989 mercury topaz?
The battery light is for low alternator output voltage. Try testing the alternator output using a miltimeter and if its less than 13 volts your alternator isn't putting out what it should. If it has low output check the belt tension and all wire connections before replacing alternator
Why is battery lamp on 87 f150?
Check the output of the alternator--should be 14.2 volts
What should the voltage output be on a 1991 Capri alternator?
13.5 to 16 volts DC.
93 Ford Aerostar alternator light is on you had the alternator check and it comes out good what else should you check?
There are times when the alternator will test out fine as far as amp output and voltage output but if your alternator has a weak diode(s) it may trigger the light to go on. I hate to say you should replace the alternator, but your charging system is pretty much self contained in your alternator so I believe the problem is in fact in your alternator. Good luck.
What are the wires for on alternator?
There should be a heavy wire called the Alternator output wire, It carries power from the alternator to power your accessories and to maintain your battery. The smaller wires usually in a plug are either the alternator's voltage sense, Stator/ACurrent/Tachometer output, regulator/indicator light. or if its an Externaly regulated alternator they will be alternator Field, Stator/ACurrent/Tachometer. hope this helps

What part of an automobile supplies current?
Alternator and battery
Will alternator still work if the gauge is not?
An alternator does not need a gauge to work. It is used to monitor the output of the alternator.
