Yes the battery will run dead after charging it very quickly. If you put an alternator to the test with a DC volt meter it should produce at least 13.2 volts even under a heavy load. Any Autozone or Advance auto parts will test the battery and the Alternator for free.

A batterty sign is turn on instrumental panel. What should be the problem? You can answer in Spanish or English. Fredyz


If the belt is still on and properly tensioned, it usually means a bad alternater. A bad battery is also possible, At many shops they will test this for free if you are going to have them do the work. If you want to do the work yourself, tell them up front and there will probably be a modest charge for diagnosis.

My alternater light has come on my vw passat is it the belt or the alternater itself?help


If the alternater light has come on in the car that means that the alternater is bad and you need to replace. You can also have it checked at your local auto parts store if you would like.

Good luck

Alternater not giving enough power


Check wiring on alternator and battery. Also be sure that there are plenty of ground straps. there should be one from battery to body and body to motor. Without enough ground this could also cause your problem.

Not charging


First tell me why you don't think it's charging.
Because of the voltage reading you are getting at the battery terminals? The range you want is between 13.6v to 14.2v. The higher the voltage the lower the amps. and true the other way, the lower the voltage the higher the amps. If you get a reading of 13.6v or lower, the alt is nearing or at max output. An alt can only run at maximum for around fifteen minutes and it will start slinging solder from overheating. It's a good indication the battery is either totally dead or junk. Charging above 14.2 the alternater is running wide open and is only putting out high volts which will cause the battery to boil , in turn destroying it. This is a bad alternater. All alternaters have integrated voltage regulater with the exception of ver few of the earlier ones. You cannot test an alternater by removing a battery cable to see if the engine keeps running without taking great risk of damaging the alt, regulator. So tell me why you feel it isn't charging. Remember an alt is not made to charge dead batteries. Their sole function is to maintain the battery charge. Without a battery, the alt won't last 10 seconds.
Hope to hear from you and good luck.
