Will your 1990 560 sel keep running if you unhook the posotive terminal to do an alternator test?
Please don't EVER EVER do this! Without a load on the alternator, if it is indeed in operation it will "full field"...essentially run wide open...destroying itself and most of your on-board electronics with it.

How to tell if bad cables or bad alternator?
Answer
Hey there friend To check if alternator is false or not there is a simple way of doing it without getting to tear entire car and cables apart. Before you do anything loosen the negative cable but so its still connected to batter.
Start the vehicle, if cant slave it off and start it, while vehicle is runing disconnect the negative wire that you have loosened then if vehicle is runing its good if it dies then your alternator went bad and needs replacment.
If you need to drive badly because cant get a ride to get to schucks or some auto parts store you can bang the heck out of the alternator with a hammer which will charge the coil inside and will loosen some of the dust that collected there. That should be enough for you to get to store and back.
Good luck you can always Private msg me if you have any other Auto Questions.
Good Day.
It is the alternator. I have a 95 Monte Carlo and this has happened to me twice in the 3 years I've had the car. Each time I had to have the alternator replaced. The first time I had a problem with the alternator I took it to a shop and had it fixed. Two years later the alternator went out again without warning. That time we took it to a different shop and bought a new alternator with a three year warranty so it'll be free if it goes out two years later again.

How do you replace the voltage regulator on a 1986 Chevy Celebrity?
It is in the alternator.
The voltage regulator will be inside the alternator. Replace the alternator, or take it to a place that rebuilds/fixes them.
It requires metric sockets, internal torques sockets, a soldering iron, a small flat screwdriver and some thin wires or drill bits.
There is a plastic cover on the alternator over the connections for the voltage regulator, these need to be taken apart with the soldering iron and flat screwdriver to be able to take the alternator apart. Then remove the housing bolts (pay attention to how the two halves line up with each other) using the internal torques sockets. After separating the two halves of the alternator look at the brushes to see if they are too worn, also check the bushings for play. If the bushings are bad replace the alternator, or have it rebuilt. If the brushes are worn, they can be replaced, but try not to lose the springs. If I remember correctly the voltage regulator is held in with 2 small screws, removed with a metric socket.
Putting it back together, bolt in the new regulator. push brushes into the slots and hold with wire or drill bits. Put two halves together exactly as they were before, re-solder it, remove wires or drill bits and replace the plastic cover.
Also, when you have it apart, is a good time to tighten the hot wire stud if it is loose.
I did this on one of mine and the $5 voltage regulator gave me another year of use out of the alternator before I had to replace it.
How do you change the alternator on a 1995 Chevy Astro?
Two bolts on front of alternator are easy to get to, bolt on back is hard. Unbolt the tranmission and engine dipstick tubes from each other up top. Jack up and remove right front tire. Seperate engine dipstick at side of cylinder head. Bolt is a 10mm head that can be got to inside of wheel well.

What wire goes to the f on the alternator?
If this connection is used, it is generally connected to the light in the dash that shows alternator fault (NOT the voltage gauge!) and then through the ignition switch to the positive battery terminal.
Use a tester to see if the charging system is working properly. If your model has a separate regulator make sure it is working properly. Make sure that your battery is ok, a battery with an internal short can cause the charging light to stay on.
The engine computer is the voltage regulator.

How do you test if an alternator is charging the battery?
Answer 1
If you have a major chain auto parts store nearby, it would be easier to go there as most of them have the proper test equipment and will simultaneously test the alternator, battery and related circuits for free.If you want to test it yourself, you will need a volt/ohmmeter [also called a VOM].
With the VOM selector switch set to the 50 volt DC Scale, and the engine running, touch the negative [black] probe of the meter to the negative post of the battery [black cable attached], and the postitive probe [red] of the meter to the positive terminal [red cable attached] of the battery.
Depending on the type of vehicle, charging system, and some other factors, the meter voltage reading will vary. However, the meter should read at least 13.5 DC volts minimum to about 16 volts maximum. If you have set the meter selector and connected the probes properly, and the indicated voltage is within this range, then the alternator is working properly.

How do you change the alternator on a 1993 buick Skylark?
You have to remove the drivebelt as part of the process. You'll need a special tool for it. Ask any big auto store about it, or a GM service center. On mine, I took a look and really didn't want to mess with it.
