13.5 to 15.5 volts.
dc
To help produce voltage.
Output of the alternator is controlled by the voltage regulator.
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.
Yes, and internal diodes convert it into dc.
the alternator voltage at the battery should be between 12.4voltsv-13.6 volts
it will not produce voltage or high enough voltage when running should be around 14 volts running
It should produce 14.5v +/- and it's DC.
The s10 uses an alternator and regulator to produce voltage. A high voltage is most likely caused by a faulty voltage regulator.
No. The alternator has to be turning to produce the charging voltage. It only turns when the engine is running.
I'm not sure I understand your question. An alternator will have to produce 13 volts to charge a battery at 13 volts. Most alternators are able to produce 14+ volts but the range is 13.5 to about 15.5 volts.
Voltage flows from the alternator not to it. If it is outputting no voltage it is defective.
