Contrary to popular belief, an alternator does not constantly produce electricity. It cycles on and off as demand goes up and. The battery buffers it from the electrical demands of the car, and it only works enough to maintain system voltage.

However, with the demands placed on the system by heat and by extraneous electrical devices i. The average alternator now is lucky to last years, which is why a prematurely dead battery may actually be caused by a dead alternator. And this doesn't include amperage requirements for items like cell phones, laptops, CD players, boom boxes or additional lights.

Understanding the importance of having an operational warning light for the alternator idiot light is crucial to catching problems early. In most modern systems, the electrical current passing through the filament of the warning VW Passat 3C2 2005-2011 Vetech Battery 95Ah Electrical System Replacement Part is what energizes a circuit in the alternator to start charging.

If the light comes on, the wiring is okay but the alternator is defective; if the light still does not come on, the wiring to the light circuit and the bulb should be checked.

Don't forget to check the fuse that VW Passat 3C2 2005-2011 Vetech Battery 95Ah Electrical System Replacement Part the light circuit. This fuse could be labeled differently in various cars. It could be labeled "charging", "regulator", "meters", "gauges" or "engine".

In some cars, if the fuse is out, the idiot light will come on but may not go off. In others like GMa burned out fuse may make the warning light work in reverse order; that is, when the key is on, the light is off but as soon as the engine starts and the alternator starts charging, the light will come on.

Checking out these simple circuits first can greatly reduce your troubleshooting time and unnecessary replacement of your alternator. As we delve further into charge light indicators, we find that in some cases it is normal for the charge indicator light to come on when nothing is wrong with the alternator.

According to information published by GM, any car may have a low voltage reading or lights that dim when electrical loads are heavy at idle.
