Make sure battery posts and cables are clean and tight, same thing for connections at the alternator and starter. Use a voltmeter to test for parasitic draw. Attach meter between positive post and positive cable (cable disconnected), with meter set on amps, and pull fuses one by one until you locate the circuit.

New Alternator wont hold a charge


Alternator generates power to the battery. The battery is not holding a charge? How old is the battery? Do you have a test meter. Check the output voltage of the alternator, it should be about 13.5 volts. Check battery connections and make sure they are clean and tight. You can do a simple test for battery strength, with a freshly charged battery, turn the headlights on, try and start the car, if the lights go dim, the battery is weak.

Lights are dimming, gauges are zeroing out while i'm driving. Could this be my alternator? Because car has new battery and starter.


If your battery is charge indicator light does not come on and battery is holding charge after a couple days of driving it is unlikely your alternator is faulty.
If the lights are dimming on youe meter cluster only, it could be a bad connector to the meter cluster.
If your head light are dimming it could be a bad battery connection or the alternator.

Issue with dash lights dimming while driving,


If the battery and alternator tested fine. I would have the charging system rechecked when engine is hot and at high rpm's. This way the checks are being done as if you were driving and driving for a long time. Alternators can work fine when cold but weaken when hot or stop working. This problem is not rare but only is seen occassionly. Unless it was checked at an electrical shop the average shop doesn't run these tests for they don't see the problem often enough to automaticly run them at all times. Good luck and let me know how you make out.

Low voltage, the battery runs low when running the car


What is the voltage you are reading? Is it below 13.2 or so? Also have you checked the current with the engine off to see if something else is working that should not be on. I ran across this twice while working on a truck and car. A relay that was wore out keep trying to close and would drain the battery every couple of months. Sometimes you can hear them clicking or buzzing. Touching them sometimes they are warm or real hot. But that is not a sure sign it is bad. In my Trailblaze they get hot but are ok. Another thougth is the belt on your alt, correctly set to spin it at the right voltage. I have ran across this many times lately with serpatine belts.

Battery light is on


the Alternator (this keeps the battery charged) is not charging the battery, the lights dim due to the battery voltage dropping low, go to any Kragen or Autozone and have the battery and the Alternator/generator tested, it is free.

Headlights go Dim


Hi

Check your alternator belt tension, if its ok, all connections behind alternator are good.

If the problem is still there, a new, or reconditioned alternator, seems the only answer !

Good Luck !

Please give me a Fixya Rating.... I need to be a Guru !
