Alternator Whine fix
OK, I had horrible alt whine when I added my subwoofer amp. I searched the forum and found a ton of "suggestions" mostly suggesting my alternator was bad (it is 2 days old), rewire everything, reground it all etc....BUT....I made a quick trip to Wally World(Wal Mart), bought a noise eliminator the gets rid of ground loops on RCA plug circuits, plugged it in and voila....no more whine! Zero period, much easier fix than most, I just wanted to pass this along in a new thread because there were a lot of threads on this topic.

Electronic filters and HUGE capacitors can help. I mean something between 1 and 5 Farads, like this :

I've got one in my car and it's very effective if the whine is coming from the alternator, fan blower,...
but it will NOT change a thing if it's coming from the ignition components ( spark plug wires and distributor ).
In this case, use only good shielded wires, avoid ground loops at all cost, and use a good ground for power and signals.
