It's cracked in like 10 different places from the previous owner's 45mph accident T-boning a car. :012: So what I'm trying to say I guess is that any properly-functioning alternator, old or new, should do this.
Is it really idling at 200rpms...seriously? I wouldn't think that the engine would run at all if it were turning over that slow. My normal idle is 750. With full electrical load, my V-belt shrieks and my engine idle drops to ~500. Just trying to give a ballpark figure.
