alternator question

i got 2001 clk 320, does our alternator takes 115 amp or 120 or 150??
i searched online and said 115 or 120
i called the dealer and said 150 and it will cost 645 plus taxes.
any help, i would appreciate it
im lost...
only reason i asked,i got that warning in my dash saying the battery/alternator and i checked the battery on the ac cluster, so its 12.0.
then i read some of u said it could be the voltage regulator??? i m guessing the alternator since it was making a weird sound for a while.

Even if it were the alternator itself, you can have it rebuilt. Just check the yellow pages / Internet search for a starter/alternator rebuilder near where you live. The last alternator I had rebuilt cost me about $80 and it took 90 minutes. Although I have SERIOUIS doubts that anything except the regulator is bad.
