I am not complaining. I am just saying that in my opinion this subject has been beaten to death lately. I have seen it several times. There was even one recently where someone offered to drive to a lady's house to fix this for her!! (She didn't take them up on it). Admittedly, the search function on the site is not always the best and there would be great benefit to some kind of subject indexing function, but the software is canned, so will not be changed. Bottom line: You need to find a different shop. Maybe someone can suggest one in your area. As far as someone here having seen this before, there have been many responses from these people with all the different causes they listed, including some I never heard of before like the alternator field winding. Maybe it is one of these things, or it could be something else. I was a bench tech for 6 years working on the same controls over and over and it always amazed me that I rarely saw the same exact thing twice, even after 6 years. To find the problem you have to go from A to Z. I good tech can do this. Others can only shoot in the dark.
