Starter, alternator wiring diagram

Would need to post year make and model for a diagtam. In all probability when the battery got shorted out by the pulley it damaged the voltage regulator inside the alternator. Make sure all your connections are clean and tight.

Car not starting

your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your buick dealer to get a new one,they are programmed for each car only,you cannot bypass it.

What do you mean by, "then it burns up alternator" ?

It is common for people to replace their battery assuming its bad when actually it is an alternator issue all along. A weak or dead alternator will make the car run off the battery until the battery is too weak to either keep the car running or start the car again after you shut it off. Have you taken the vehicle to an auto parts store that will test your Alternator, Battery and Starter motor for you with their test computer? Many offer this service for free and it only takes a few minutes. Another issue could be the battery cables and or their attachment points. Sometimes cleaning of the battery terminals works and other times the corrosion has actually seep inside the stranded wire battery cables and reduce their ability to carry the needed amperage. When that happens replacing the cables is the best bet.

If the battery is good then most likely the starter again.

Alternater wont charge battery and fusable link on starter keeps burning

Bad voltage regulator. Usually built-into alternator.
Start car and unplug battery, if it dies your alternator is dead. Get new alternator. If car keeps running, get a voltmeter and check voltage coming through - should be higher than 12v but less than 18v. Any other number means your voltage regulator is dead, cheaper to get a new alternator.

Car died, repeated clicking noise when start attempt...

The clicking is the Starter Solonoid not getting enough CCAs from the battery to start it.
While running - the alternator should be able to charge the system to 14.4V.

11 volts you are experiencing tells me your alternator is faulty.

Your dash and other items were turning off/on while driving because the voltage probably dipped below 8.4v.

Your vehicle runs off the alternator power once started. The battery is only there to get the engine spinning initially.

A backyard mechanic's way to test the alternator is to start the vehicle - then remove the positive wire on the battery (coming from the alternator).

** If the vehicle stays running - the battery is problematic - probably a dead cell - have it LOAD tested at a local parts shop for free.

** If the vehicle dies shortly after removing the + battery wire - the alternator is failing - and replacement is necessary.
