alot of noise being picked up

[Lucky 76 5]

I am getting a lot of different noises coming out of my speakers. I have had this problem for a while. I thought it was my pioneer head unit but I guess that proved to be false. I have installed all new grounds and everything is wired correctly.

I am getting not only alternator whine but ...

noise from when I turn my fans on (ac/heat etc) and the noise increases as I increase the fan speed

noise when I turn my signal light on or yield lights on - they noise pulses to the clicks of the signal lights

noise when I turn my interior lights on and as the lights dim the noise dissipates.

The wierd part is, if I turn my car onto accessory the noises are no longer there. These noises only occur when the car is running.

It sounds like a factory ground issue but I am not sure. I would like some input from you guys. Thanks!

I am just hoping I don't have to go through all of the vehicle grounds and retighten them to find the problem

[Lucky 76 5]

This problem also occured before I did the big 3.

Either a bad cable or ground. I'd test the cables first as it is the easiest.

I doubt it is the rcas. When I say I replaced everything to get rid of this noise I have. I had the $120 tsunami rcas in there and I had the noise. Then I switched to the Knu Krystals and I still have the noise.

is this the 2003 Lincoln i see in your sig. funny you say all those problems are you sure there is no radio noise suppressor in a circuit in the autos wiring. i had a problem years ago with a radio noise suppressor in a Plymouth reliant k car because the capacitor went bad. how i found it i needed a wire diagram to find it but check auto zone or buy a Haynes or a Chilton's auto manual for your vehicle with the chassis electrical diagrams. and engine diagrams some time you got them on the ignition system too. this is if you do not find a bad ground.

[CrazyKenKid 64]

sorry you said it is not the h/u? did you swap h/u to make sure of it?

sorry if you already answered this.

I know i had the SAME issue with my car for 2years straight and i did everyhtin you did to the T and the noise was still there and very annying. i changed rca's grounds i used groud loop isolators i did everything the works and nothing worked. i got all the noise you had when the fan was on when the engine was on when i was speeding and everything.

then i purchased a bnib h/u and BAM all gone and never retured (knock on wood) and i didn't change a single thing jsut JUST the h/u.

but i don't know about your b/c it sounds 100% like my issue back in the day of my PIONEER H/U!!!

I did not know cars had radio noise suppressors built in to the car's circuit from the factory. Would this be something a certified lincoln technition would be able to locate and repair if needed?

If not, will this manual do if I buy it?

Who do you think told you about the pico fuse in the pioneer head units ahahah. Yes I replaced it and I still have the engine noise.

I have the same exact problem in my crownvic. Does your noise change pitch when your engine revs up?

btw a lot of the new car have so much electrial wraped up in them like my 97 taurus when ever a relay goes bad. the power window's don't work the stereo the dash gagues don't work ton's of stuff because of one relay.

I am looking through the schematics and I have no clue exactly what I am looking for. What exactly am I supposed to be finding and where should I look?

[2000LaDe 1]

have you tried running power and ground directly from your battery to your cd player and tap the turn on wire to your ignition wire?

I think I tried that on my old radio. I am going to have to give that a try with the new one just in case.

[Lucky 76 5]

I found a couple of the caps on the ignition coils. They are called the ignition transformer capacitors and have a number 18801.

I have tried noise filters and they do not work. They also decrease the output signal on the rcas.

Are you using any of the factory ground wires on your equipment
