hey guys,

i drove my car for a ride, and noticed loud "buzzing" "whiring" i dont know how to explain well in english.. it are electrical noises, and i hear em very well from the inside of the car! if i pull the hood it is not as easy to hear than from the interior. i thought its the alternator pulley or something, but if i rev the engine, the noises dont go faster. and i noticed that the noises become a bit louder if i flash the headlights!
my battery and alternator voltage seems to be nice, about 12,5V with the car shut off, and about 15V with the car running.. wtf could it be?

oh yea, if it helps to figure out the problem: the noises were quiet as i drove to my friend, 2 hours later we went out, and i redlined one time in the 2nd gear. but didnt notice some badly noises. after that i did a small burnout on my old tires, it wasnt that long.. the tires smoked up for mayb 2 seconds and i dropped it, i wasnt longer than 6 seconds at 6k rpm during this action.. but after that the electrical noises became more loudly! did i damage something? the car is running fine, and i warm it up every time i drive it harder..

 

15V is too high.............should be between 13.5 and 14.5. Something could fry.

 

i dont know if it realy was 15.. i measurred one time about 16,2V i think..
i hope i meassured right, its at the battery if the car is running right?

 

i started my car today in the morning, and the noises are away again... no electrical noises, nothing.

i measured again, engine was fully warmed up. car idling: 14,2V, increasing to 4500-5000rpm measurred 14,7-14,8.
turned all electrical things on, stereo, headlights etc. at idling: 12,7V, increasing up to 5000rpm again measured: 13,5V.
is this ok??

the noises will come back for sure.. its not the first time

 

wasn't a real warning buzzer im assuming.

do you have any better way to describe the noise or location.
make an *** out of yourself trying to describe what it sounds like. itll be funny

 

lol

mayb i can take a soundfile with my cellphone or cam. its kinda difficult to describe.
zzzRRzzzRRzZRZZRZZZRZRZzzzRZZRZRz gRR zRRR

 

any idea what it could be?

my boost gauge is crapy, it won't move over 0 psi most of the time i drive. a few days ago, i noticed that the boost gauge works a LOT better, if my car is doing this electrical noises, wtf!
the needle is freely sliding up and down like it should do! if the noises are away again, it works like junk crap and moves only after full load up to 0 psi.. but the car's POWER is ALLWAYS the same and is pretty nice :/ even tested with a mechanical boostgauge, 8psi under full load because my cat-back system is full of holes.

 

I hate to post *****, but that is the FUNNIEST post I've ever seen.

 

lmao
