Alternators have two parts, one is the armature that generates electricity and the other is a voltage regulator. In most cars the typical output for an alternator is 13.2 to 14.4 volts. If their is more or less than this being produced, the voltage regulator may be faulty or the bushes may be worn.
another issue that some alternators have is the failure of the bearings inside the alternator leading to noisy running or the bearings inside the freewheeling pulley fitted to more and more modern alternators. these can often be replaced independently.
It varies depending on how much other electronics you are using on the vehicle at the time. Could take hours. I do not recommend you charge any dead battery with the alternator if you can avoid it. it puts too much of a strain on the alternator and may damage it. Charge a dead battery with a battery charger.
15.0 volts is maximum for most systems some batteries will not stand even that much. have battery tested as a bad battery can fool an alternator into overcharging, check all connections and be sure that they are clean and tight.
Yes, if the voltage level is too low to start the car.
take it to a mechanic!!!! would cost too much to do it yourself, and if you messed it up.....
Get your alternator tested at autozone,its free,and check your battery too.
Anything below 13 would not be holding enough charge but anything over 16 too much. So between 16 and 13. If you are at a smack dab 18 than it is over charging your battery. Hope this helps! I have a 93 Grand Prix
Traffic law attorneys charge too much for their service.
Check battery connection Check alternator Too much fuel should not be a problem
it depends on where you go, or what kind. but try walmart- they have everything, and at low prices too!
The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.
If that's dollars it is.
It means that the voltage is going up as the alternator spins faster. 4 posibilities; 1 Your battery is dying and the alternator is working harder to charge it when you accelerate. The lights are comming up to full brightness. 2 You have a bad connection at the battery terminals or frame ground and the battery can't hold the voltage down. The lights are receiving too much voltage and are more likely to fail. 3 The voltage regulator on the alternator is failing and overcharging the battery. The lights are receiving too much voltage and are more likely to fail. 4 The battery needs water. The lights are receiving too much voltage and are more likely to fail.
