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.

How do you determine what is drawing the battery down after you already changed the battery and alternator?
Disconnect the negative cable and connect (insert) an ammeter between the battery and the battery cable. Remove the fuses one by one and see which causes the current draw to drop.
What part of an automobile supplies current?
Alternator and battery
How do you know you need an alternator or a battery?
It's easy to distinguish if your car has a damage alternator or battery. The first thing you do is to start your car using your old battery then, once the engine is running then remove the cable from your battery, if the car still running that means the alternator is still charging but is it enough? so you have to measure the current that is being generated by the alternator using a multi tester. If the reading from the tester can reach 13 to 14 volts then your alternator is still good. If not then the carbon brush of the alternator might need to be replace or the IC. If your car battery is already leaking then it possible that the plates are already damage, or if you have tried to charge your battery but the power is easily drained then it needs to be replace. i hope this can help ......... deep
Which component controls the amount of current that the alternator sends to the battery?
Regulator.
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.
What does an alternator produce?
An alternator produces direct current that is used to charge up the battery while the car is running.
How can the frequency and voltage of an alternator be changed?
The frequency is changed by varying its speed, and the the voltage is changed by varying its field current.
What is the purpose of a alternator?
A car alternator generates alternating current, then uses a rectifier to convert the alternating current to direct current, it charges your battery and supplies the current to run all the electrical systems in the car.
Do you need a voltage regulator if you have an alternator?
yes to regulate the current before it in to the battery.
What is the component in the alternator is responsible for direct current for charging the battery?
Diodes and rectifier
How does an alternator keep a cars battery charged?
An alternator has diodes which transform ac voltage to dc voltage so that the battery gets negative and positive current on its poles thus making the battery to be charged.
What is alternator do?
This is an easy answer. The alternator is hooked (through wires blue and black) to the battery. So every time you start an engine the alternator kicks on and charges the battery. That's practically how it works. <><><> To add a bit to the above- an alternator produces an alternating electrical current (unlike a generator, which produces a direct current- DC vs AC) On modern cars, the alternator produces the current used to charge the battery, and operate electrical equipment on the car, such as lights, wipers, radio, etc.
