Well, based on the always informative information on this site I've determined I need a voltage regulator for my alternator on my ML. The dealer has one for $50. Has anyone replaced one of these? What is involved? Thanks!!!
Thanks, I did do a search on voltage regulator and voltage regulator replacement and didn't find this, am I doing the search wrong or looking in the wrong place? Do I have to pull the alternator out or can i replace the regulator with it in place?
43sqd, thank you for the info. This will be my first time working with the belt system of the ML. I'm thinking I will have to take tension off of the alternator by loosening the belt before I can remove the alternator, correct? I've done that on other cars, how do you do it on the ML? Again. thanks for your help. I picked up the new regulator at lunch. 003-154-52-06, the dealer gave it to me at cost, $45. Jeff
The below pdf shows how to remove the belt, but in your case you don't have to do that, nor do you have to remove the fan and shroud. Just take the tension off the belt and slide it off the alternator and then remove the alt. Here is a diagram and instructions.
Thank you 43sqd and others on this great site. Sure enough, the replacement of the voltage regulator has the 104K ML up and charging like new again and for only $45! That was definatly the issue as I had a shop check and now I'm charging again. Thanks again!!!
