Why is my 1990 Chevy van G20 alternator not charging and is not getting power?

The alternator is not getting power? At any of the wires or just the main/largest one? If you are testing the large wire, this is the output side that runs to the battery. If there is no power in this wire where it connects to the alternator it must have a bad connection at the alternator or at the battery or a break somewhere in between. If there is power there, I would look at the fuses.

∙ 12y agoif u know that you have a known good battery, and a known good alternator then check for a bad alternator wire. a replacement pigtail can be ordered from most auto parts stores for around $2 - $10 it splices in to the original wire, and it is usually the plug end that gets cooked (burned out) over time.

1999 grand am se Check the altinator to see if it's charging the battery?
First start the car then pull off the positive on the battery if the car dies than you need a new alternator if the car keeps running u may need a new battery. A word of caution, testing an alternator that way can cause damage to the alternator. The alternator needs power to make power unlike the old generators from the past.

I use the public library. They have an entire section of automotive reference books including professional manual with wiring diagrams that are much better than those found in do-it-yourself manuals.

On a 1972 Chevy blazer with a 350 in the charging seystem ran through the starter?
no the charging system consists of the battery and the alternator. the battery being the starting point of the system. the battery provides the initial power. the alternator then keeps your battery charged while the motor is running. the starter gets its power from the battery but has no relation to the charging system. the starter has but only one function and that is to power up upon initial start up and turn your motor over to get it running. hope that helps you out a little bit.
Your Chevy s10 battery light came on but it gits 12 amps of power is this enough or should you look at replacing alternator?
That's not 12 amps,that's 12 volts,which means the system isn't charging Measure the voltage across the battery terminals,if its charging properly,it will be between 13.8 and 14.7 volts,anything less and its not charging. Suspect then a faulty alternator or wiring problem. and have the battery properly recharged and tested too,a low battery will not give you a correct charging reading and a faulty alternator can take its toll on a battery.
Is it the alternator when i have no power on my subaru?
If you have no power to anything, and your battery isn't dead, then you more likely have a bad ground. If the battery is dead/keeps dying, there's a good likelihood that the alternator isn't charging it adequately.

What is the function of the pully assembly on the alternator?
that is the drive assembly which the power provided by the rotation of the crankshaft and through the engine drive belt causes the rotaion of the alternator which produces the electrical power to the auto and battery charging system
Is there a fuse that keeps the alternator charging?
No. The short summary is that there usually is a fuse or circuit breaker in the line coming out of the alternator that protects the alternator from a sudden surge in power from some outside source and which also protects the engine's electrical parts from a sudden surge that might somehow come from the alternator (very doubtful this would happen). But that fuse doesn't keep the alternator charging in the strict sense of the phrase. What stops an alternator from charging is internal parts failure such as the burn out of a rectifier, bearing failure or the belt which drives the alternator failing or coming loose and slipping excessively. Short of failures such as these an alternator will keep on charging as long as the belt is turning its pulley and causing the rotor inside the alternator to turn.
Why don't I have any power after changing the battery on a 1993 Geo storm?
Your alternator might be bad and not charging your battery properly.
My volts warning light comes on in my 1999 Chevy Lumina What does this mean?
Either the battery is weak and not charging properly, the connections are dirty on the terminals of the battery or the alternator is not putting out enough power. If you rev up the van does it go out or is it on while you are driving?
As the car battery is charging should the meter move back and forth?
Not really. It should only move a little bit. If the alternator is not producing full power at idle, you may have a bad alternator.
