According to my haynes manual, my stock alternator puts out 55a. I have an alpine car audio amp that I know has a 30 amp fuse and I remember reading that the electrical things in your car slowly draw more current as they age. So i know that altogether there should be way more than a 55 amp demand in my car. My question is what will my alternator do to show that it is being overworked? I think it is right now because of my weird stalling and occasional starting or screeching noise while starting problems. Are these alternator related problems? What is the biggest altenator that i will be able to buy from my mercedes dealer or the parts shop here?
