[QUOTE="Jonny Hogan, post: 2400063, member: 569618"] Could you give me your advice on the following ? I'm experiancing the dreaded alternator whine through my speakers (i'm using infinity components up front and back and a sub in the boot of my E36 M3 Convertible - i have a dedicate alpine amp for the comp's and JBL mono amp for the sub). I've tried a number of diagnostics to get rid; changing power supply, checking and double checking all wiring ets but the noise persists. There is absolutely no noise when the car's engine is turned off. I would say that my alternator has always been noisy though and i've noticed that the whineing noise increases markedly when i switch on my headlights etc is there anything that this particularly points to?. Could it be that me alternator itself is actually causing the noise and is faulty and or on the way out (i'm not having any problems with flat batteries though)? Your advice would be most, most appreciarted as my beloved car's in bits again [IMG]//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif[/IMG] Jonathan [/QUOTE]
