[QUOTE="moorezy, post: 6397348, member: 578973"] I'm starting to lose it.. I'm trying to troubleshoot some alternator whine... Things I have: Pioneer 4000dvd.. Triple Shielded Klarity RCAs.. Big 3 in 1/0.. Kappa Amps 200 amp dB electrical alt Things I have tried: Swapping unit to a JVC 810 ( Pioneers known to have RCA issues ) Grounding RCAs Running RCA right from unit down middle of car to rear ( to eliminate chance of small power wire I have on RCA side ( but they are triple shielded so just ruled out that because it still whined ) Things that are weird: When I do a rev my voltage hits 15.4 which throws amps into protect. ( 15 volt cutoff ) So i'm thinking that increase in voltage is spiking everything and making the whine I'm not sure if I did an alt ground with 1/0 so i dunno if thats making it spike What should I do? I just want to have no noise... and everything to work properly... What i'm thinking is take out this alt, throw back in stock 120 and roll like that. I am only running around 1200-1300 RMS and I have big 3 maybe get a better bat.. ANY INPUT IS NEEDED I WANT TO GET IT SORTED OUT. [/QUOTE]
