I have been having a "charging" issue in my 04 w220 and was wondering if yours did the same thing? I was thinking of having the alternator pulled and replaced.. my indy sucks (they always say - we dont know, weve never seen, etc); dealer seems to be 10x better.
Any idea on how hard to pull alt and replace myself? Im not much dyi but have friends..
is there a repair manual that I can buy like I have for all my motorcycles?
if the alternator doesn't kick in til 3k rpm, that would explain my issues.
I thought I had a bad battery as when I replaced the rear main battery my lights dimming upon a cold start went away... for a month or so.. now when I start up the car somewhat hums, etc and the lights in the cabin and everywhere in the car somewhat surge - if the car is not charging until 3k that would make sense?
Any suggestions or help is appreciated. Thanks in advance..
