It depends on where the wire is being connected on the alternator. It could be the alternator or it could be a damaged wire or connector. It's something that you will need to track down.

What is the exciter wire on a GM alternator?

It is the wire that supplies the initial field current to the alternator from the battey. Once the alternator is rotating the field current will be provided by the diodes from the current produced by the alternator. excitor wire is usually wired through the charging indicator light.

What is the component in the alternator is responsible for direct current for charging the battery?

Diodes and rectifier

Does alternator need to charge after replacing it?

No, the alternator is the charging device which runs off a belted pulley attached to the motor. The alternator charges the battery which is the source of the current required to get the engine turning over and in turn starting the engine.

What does the alternator do in a cars electrical system?

Function of Automotive AlternatorIt generates AC [alternating current] electricity which is rectified and converted to 12 volts DC [direct current] for charging the battery and operating electrical devices in the vehicle.

The brushes on an alternator carry?

The brushes on an alternator carry current.

Alternator generates DC or AC?

An alternator produces AC current but it is converted to DC by the rectifier inside the alternator.

What is a alternator?

The devices that develop electric power are a generator (for direct current), or an alternator (alternating current). In a car, an alternator is used, with a rectifier, because of size and weight considerations.

What is wrong when the alternator is charging and the car still looses power and shutoff i then jump start the car it runs but only for a short while then shutdown?

Engine Dies, but Runs for a while After Jump StartingIf you're sure the alternator is working properly, I suspect that you have a loose, or disconnected, connection of the conductor [wire] that is supposed to carry the alternator charging current to the battery, OR a battery that has become defective.

What is an alternator?

An alternator is an electric generator which produces alternating current through mechanical means.

Is a car alternator ac or dc?

The word 'alternator' means 'producer of alternating current'.

How do you calculate the excitation voltage and current of an alternator?

formals to calculate exciation voltage of alternator

Is the voltage ac or dc from a new car alternator?

The CURRENT is actually AC coming Directly from the Alternator. A voltage regulator/converter then takes it to DC. For all practical purposes, a typical automobile operates on 12Vdc. The Alternator actutally puts out about 14 Volts to allow for constant charging of the battery.

What is an alternator for?

The alternator generates power to run the car and charge the battery. An alternator in a vehicle generates Alternate Current (AC) instead of Direct Current (DC) electricity to power the vehicle.

Is an alternator and a starter the same?

No, and alternator generates DC current. A starter just uses DC current to start the engine.

What can cause the alternator cable drawing current from the battery on a 2003 beetle. the alternator has already been changed.?

Disconnect the cable from the alternator and see if that stops the draw. If it does, the alternator may be defective. Otherwise there may be something else drawing current.

Can an alternator short out for years And have problems for periods at a time for a matter of 3 years or so?

An alternator cannot "short" out for years or even minutes. The definition of a short is a wire or circuit touching ground to cause a fuse to blow. The circuit is too "short" for the current to flow through the proper load and back to the battery. The voltage regulator in a alternator can act up from time to time and cause improper charging from the alternator. Or a component of the alternator can go bad and cause a charging system problem intermittently. Your question needs to be explained better to give a better answer.

What is alternator in motors?

The Alternator is a component that acts like an electrical generator, charging a battery and powering necessary electrical systems. They are usually used in place of generators because they are lighter in weight, simpler to operate, and produce alternating current.

How do you check the alternator output current?

with the alternator running at around 2200 rpm (for most alternators this is topout meaning it is producing as much power as the rectifier will allow) an ammeter connected to the main power out of the alternator in between the battery and alternator should show you how many amps your alternator is putting outremember that most newer alternators require a 12vdc signal to "excite"the stator this is usually supplied by a separate positive wire in the pigtail of the alternatorThe only current that will be read is the actual current that is being drawn from the alternator at the time of the test. If the battery is down in charge, it will show a high current draw. If the battery charge is satisfied, the current level will only be that of what other circuits are drawing current in the car. The current output is totally dependent on the load on the alternator. The only true way to test the actual current output of the alternator would be to have it load tested at an auto electric store. They run the alternator on a jig and do a load test.

What current would you expect an alternator to develop in the event of a short circuit?

maximun through the alternator.

What does an alternator diode rectifier do?

The alternator diode rectifier converts the AC current being produced by the alternator to DC from which most of the electronics installed and battery use.

Your volts light came on in your 1995 Chevrolet Lumina What is wrong?

You need to check your battery and alternator, to start with. If you're lucky it'll be something simple like those two. Sometimes you can get local auto parts stores to check them it for free. Typically that means that the alternator isn't charging. Many auto parts retailers will test the charging system at no cost. Their hope is that you'll buy the replacement parts from them. An automobile will run for a while after the alternator stops charging, but when an alternator is not replacing the electrical current the battery will eventually discharge and without recharging the battery SOMEHOW, with either a functioning alternator or an outside charger, the engine will eventually fail to start.

What is the function of a rectifier within an alternator?

A rectifier turns the Alternating Current (AC) produced by the Alternator into Direct Current (DC) that your car uses.

What does an automobile alternator do?

alternator can produce the current to supply in the vehicle our vehicle needs D.C current but the alternator can produce A.C current the A.C currrent can convert into D. current by diodes ADVANTAGES OF ALTERNATOR: it is light weight it is compaq in olden days generator are used but it is a heavy weight and it can occupy more space so alternators re used

Where does the Excess current produced in a alternator charging system goes?

Actually it is bled off to ground but because of a very well designed regulation system in most alternators, there really isn't anything excess. When it is not being drawn from the alternator, it goes to the battery.

Which type of current we are using ac in automobiles?

The only type of current used by automobiles is dc current although the alternator produces ac current which is converted to dc by rectifiers built into the alternator. Even the alternator is controlled by dc current though through the use of a voltage regulator which limits the amount of negative dc sent to the stator and positive dc current sent to the rotor of the alternator which limits the EMF.
