rebuilding an alternator? how much?$$
i got a friend that needs an alternator for a LS1 2000 F-body....he wants to get it rebuilt at one of the local shops....how much does that usually cost? and when being rebuilt can they "UP" the amps on it?
thanks
if anyone knows where i can get one let me know

when rebuidling they cannot "up" the amps,
you can up the output voltage for a given speed the alternator turns by changing out the voltage regulator with one that provides more field current,
but this is not the same as making it a "high-output" alternator where if the electrical system needs 200 amps the alternator could provide 200 amps (at a specified voltage) when spinning the alternator within a given rpm.

Well when you have an alt rebuilt they only replace the failed components. Price will depend on the components replaced.Why are you wanting to bump up the amp output? IIRC the oe amp rating is 102 amp.

ive read on some of the other threads that a higher output alt will/could make the car run more efficient.
He just has to stock sound system so i dont know but if wont do much good for the money spent then.......
so rebuilt just means they replace the part that doesnt work...so in a sense some other old part in there could go bad. THat doesnt sound like a rebuild but as long as places warranty it then i guess that ok?

An alternator will only produce current in response to demand. If you have a 100 amp alternator, it doesn't produce 100 amps all the time. In fact, it rarely does. With this same alternator, and 50 amps of electrical load it will produce only 50 amps. If you shut something off that was drawing 10 amps, then the alternator output will drop by that same 10 amps. Turn something else on that draws 20 amps and the output will go up by 20 amps. Unless you have electrical demands that are in excess of your alternators capabilities, there is zero benefit to a high output alternator.
Although the guy selling alternators for a living will appreciate taking your money from you.

yeah he'll just get a reman....hell might as well be new but for half the price atleast reman is new parts all the way thru.
rebuild just sounds like a waste if all they do is replace whats bad and thats it.
Prices on Ebay are anywhere from $56 to $399..( i cant believe someone is charging $400 for a 200 amp alt)
after reading this thread the prices are crazy stupid for the alts.

Many people will believe most anything you tell them. A high output alt will not make your car run more efficiently, any more than putting snake oil in with your oil will.
