I want to first say thanks for the replies. This is not my car and I have no idea on how many miles are on it. It is owned by my fiancee's ex-in-laws(ex-husband's parents).
They took it to a shop because the car was making noise and some light was on in the dash and the shop told them it was the alternator going out and wanted to charge them $400 to replace it.
A re-man alternator for this car is right at $170 and none of the parts stores I checked had a new alternator for this application. I don't like using re-man alternators but they just want it fixed and don't care.
I have not seen, heard, or saw what lights may be on, on the dash. They just want the alternator replaced before it fully goes out.
I have no idea if that is really what is wrong with it. I will look at it and put it on my scanner before I do anything to get an idea on what kind of output the alternator is putting out and see if it's in fact making any kind of noises.
I have used Alldata in the past and like it but It doesn't make sense paying for a subscription for a car that is not mine.
Thanks again for the information.
