You might also want to try a new/different LOC. This is most likely where you are picking up the alternator noise. If the LOC has a ground wire and you have not connected it, connect to a good ground and this may reduce the noise. On the other hand if the LOC has a ground wire which is connected, this may have created a ground loop at the radio. Try ungrounding the LOC and see if the alternator noise is reduced.
