How much voltage the alternator of Skoda octavia gives?

the alternator voltage at the battery should be between 12.4voltsv-13.6 volts


Should the volts shown on the DIC for a 2001 Aurora flucuate or should it be a steady number?

they should fluctuate when your revving your engine and letting it down to idle that's the voltage regulator stopping the alternator from putting out to much power it is perfectly normal.


How does an alternator know how much voltage output?

Output of the alternator is controlled by the voltage regulator.


How much voltage is a 2001 dodge neon supposed to put out?

From the alternator to the battery should be 14v


Why is your 2000 Honda accord v6 charging 18volts?

The most likely cause is the voltage regulator in the alternator. Modern vehicle voltage regulators aren't serviced separately, so you would just replace the alternator. That much voltage can boil the battery. Typical alternator output should be around 14.5 volts.


Your alternator is on top of the motor and what does the voltage regulator do also where is it on a 99 Concorde?

the voltage regulater is built into the alternator it regulates how much volts gives to the battery

Is there a fuse on an alternator?

no there is not a fuse built into any alternator that i have seen to date (been a mechanic for 10 yrs) HOWEVER most vehicles have a charging fuse located either in-line or at the fuse panel so that if the rectifier or voltage regulator goes out the battery does not receive too much voltage or the wrong type of voltage ac versus dc in short no the alternator doesn't but the vehicle should have one in the alternator circuit


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.


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.


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.
