SUBARU FORESTER ALTERNATOR PROBLEM

2003 Subaru Forester

Electrical problem
2003 Subaru Forester 4 cyl All Wheel Drive Automatic

I have a 2003 Subaru Forester and I have just started have a problem - when the car is shut down and key removed, there is a high pitch humming sound coming from the area around the alternator. Remove the neg. Lead to the battery and the hum stops after maybe a second unless other electriical items are on (such as the interior lights) in which case it stops right away. With battery connected, remove all connectors to the alternator, the hum is still there. Moving the hod rod from or to its holding clamp by the radiatior sometimes changes the pitch of the hum. Car has 92,000 miles. Advance Auto did check on alternator and battery and they are in good condition
