weak or faulty battery, faulty alternator (or slipping alternator belt causing battery not to charge) or faulty starter motor
It can, though it is unlikely -- the alternator and the voltage regulator would both have to be faulty. A faulty alternator will not charge a battery, though, so it may seem normal until the charge put into the battery at the store runs out.
Possible causes,- Faulty battery- Alternator belt missing or loose- Faulty Alternator- Alternator harness is open or shorted- Alternator circuit poor electrical connection
The alternator may have a faulty rectifier or faulty voltage regulator
A faulty alternator, a faulty belt tensioner.
As long as the battery is charged
A quick test I've always used is to start the car. Remove the neutral cable from the battery. If the car still runs your alternator is fine.
faulty voltage regulator
That is typically caused by a faulty alternator. Have the alternator tested; the light is indicating that the alternator is not providing a charge to the battery.
It is fault P222a.
The vehicle has a charging problem, perhaps a faulty alternator.
More than likely your alternator is faulty. The alternator is supposed to charge the battery and run the car's electrical system when the engine is running. If your headlights dim it means that not enough electricity is being provided. A simple free test at just about any auto mechanic shop should confirm if the alternator is faulty. If the alternator is faulty, and it is not just due to a loose belt, you want to replace the alternator as soon as possible. Eventually it will fail to charge the battery, and you car won't start.
The new alternator probably has a faulty voltage regulator.
If the battery is sulfated (or otherwise faulty) to such an extent that it calls for a continuous charge, the alternator never gets a chance to switch off. With the resposibilitiy to run continuously the alternator overheats and eventually fails. Never replace a faulty alternator without also checking the battery.
Yes it can cause bulbs to blow.
how to turn off the service light
It could be battery connection, discharged or faulty battery, faulty alternator or regulator, faulty starter or a loose and corroded connection on the starter.
No, it has nothing to do with the Alternator. However, it will make a noise similar to a bad bearing sorta like how an alternator will sound when it goes bad. No oil in the supercharger is very bad, and will lead it to fail. Most of the time if it has no oil in it, it means it has a faulty seal and most likely your bearings are bad inside of it.
Some vehicles have an external voltage regulator which also controls the warning lamp circuit, some vehicles have a warning lamp relay and others may operate through a computor, all of which require a signal from the alternator. You either have a faulty regulator/relay/computor, A broken signal wire from alternator, alternator is incorrectly wired or a faulty/incorrect type of alternator
An alternator keeps the battery charged in a vehicle. In a 2006 Chevrolet Impala when the alternator fails the battery will keep dying and no power will be available when attempting to start the car.
The wires in the plug are backwards. switch them around
It doesn't, unless it has a faulty alternator/battery or isn't driven.
It could lead to it indirectly.
