Thanks Gilly. On the 420 there is plenty of room. On the 300, looks like I have to work from the bottom of the car as the air pump blocks most of the view to the alternator.
A little confused. I see on the back of the alternator the large wire that goes to the battery, but not 2 screws. Do you simply loosen the 2 screws and then remove the voltage regulator? Does installing the new one take much expertise to ensure that the new brushes touch or is it simple?
Maybe a dumb question, but inside the alternator is foreign to me.
Thanks a lot for your post!.
