I think you are right...the alternator may need a new set of brushes. battery light coming on and off is an indication.

a busted rectifier would not indicate an on and off light but rather a steady on light. but it has 6 diodes and one busted diode would do the same. on and off battery light depending on the load present in the system.

tnx 4 using fixya,

Draining the volts form my battery. Not sure what is causing this? I keep charging the batt. but when driven short distances, Battery not charging light keeps coming on ?

Hi, if the battery charging light keeps coming on and the battery is draining it almost certainly means that your alternator needs attention. It may be that the alternator belt is loose or is slipping or theremay be a fault with the alternator itself. A local garage should be able to help you rectify the issue quickly
Good Luck

Hi I have a Nissan patrol mq l28 Just replaced the alternator n the charge light staying on n when I disconnect battery it dies any ideas

the alternator is not working, is incorrectly wired up, has an open circuit to the regulator
Disconnecting a battery when running is a sure fire way to destroy the rectifier block in the alternator.

Battery light comes on when engine is off.

Warning on alternators never take positive terminal off battery when engine running a good chance you will fry the regulator or diode plate. Usually when the light stays on with ignition off indicates damaged negative diode in the rectifier. Try removing the warning light wire at the alternator if the light goes out this will indicate the above problem. If not then check if there is a charge relay. Please let me know if you have further problem and include more information on your findings.

What does the battery warning light mean on my 2003 Mazda Protege? Someone stole my manual out of my glove box so I can't look it up.

That battery light on your instrument panel means the battery is discharging and the alternator does not charging the battery.
Better check your engine, the alternator belt might have been cut off or already missing.
The other one will be is to check the battery terminal if it is properly connected in the battery poles.
If all these are still intact, the problem would be the alternator itself. You have to bring your car to nearest garage to check the charging( voltage ) output of that alternator something might have been broken inside it. Usually the parts inside are the rectifier diode, IC regulator, and the carbon brush.
Hope that helps you out.
Thanks for asking FixYa!

Just fitted new alternator but battery light not working

That indicator is commanded by a relay connected to the alternator. Check the wires and the relay. Or it may be just a burned bulb.

Hi I am Vortash the battery light is an indicator to if the Alternator is charging or not .. if the light is on it is saying that it isn't , check the plug and wire connections to the alternator check your earth strap from your negative side of the battery to earth or if it is a continental positive earth car check the + side is attched to the earth securely and cleanly .. check the output from the alternator you should be gettinfg approx 13.5 to 14 .5 volts DC if not switch to ac if you get a reading the rectifier has gone and will need replacing ..( most of the modern alternators come with new brushes attached to a rectifier as a single module ) Check the fan belt tension slipping belt can cause bad charge rate and bring the light on .if you are finding the car is becoming difficult to start the battery going low the fault is realy dead to rights a charging fault.. Hope this helps Vortash

New Alternator brushes, however battery light doesn't come on

using a mega on rectifiers can damage them
you should take the alternator to an auto electrician for a proper bench test
