Along with my other post today im trying to get my car running and functioning like new.
I have had a problem with alternator whine since we got the car new off the lot. Here is a list of all the systems that have had the same problem with the alternator whine.
1) stock radio
2) aftermarket panasonic cd player
3) panasonic cd player, jensen amplifiers for speakers
4) added capacitor, new speakers, new monster cable from amp to speakers
5) tried moving amps around car, front, rear, middle, use different grounds such as on the battery terminal, in the trunk, the middle of the car. I have always used 4-2aug wire for power and grounds and the paint on the grounds have been scraped away. I also tried isolating the amp from the metal of the car and also tried grounding it to the car.
6) then i installed a ground loop isolater on the rca cables from the cd player to the amp and i was able to hear my music over the alternator whine again
7) rca and power cables have always been on opposite sides of the car, i have even switch sides once to see if that would do anything but it didnt, i even tried holding the cables in the air away from the car but there was still whine.
8) carputer with same amp setup, still whines
9) then i replaced my alternator (it was going bad) from one at advance auto, i thought this would fix it but its no different
I have a feeling that its something in the engine since this problem was there with the stock radio and its obviously not the alternator since i replaced it with no difference. The alternator whine is bad when its cold outside and the engine is not warmed up, but once the engine warms up its much less noticable but this is with the ground loop isolator on my rca cables. If i didnt have the ground loop isolator then i wouldnt be able to hear my music over the whine, its that loud! Ive tried everyting ive found on this site and others, i need help.
