om...
I have a 3 month old 2004 Ford-25 p/u and if I turn my radio to AM or
my CB on,
I can hear the ignition noise in my engine and turn signals cause a
clicking, and when I put on brakes or turn on headlights is causes a
clicking noise. Teh ignition noise just about drwons out reception
completely. Ford says it is in all of their trucks and put a new radio
in for me but it is the same. Local service dept says they have no way
of knowing how to remedy the problem, and will have to wait till
enough people complain and a fix is found. Can anyone tell me what the
problem is? I have heard it may be either the fuel pump or the
alternator, but ford service says they don't know how to fix. Dearborn
will not answer my queries now. I am about to file a Lemon law
complaint with the attorney general of FL which will require them to
fix or replace the truck.
I love the truck as I have all my ford trucks but this is
flabergasting me. bob

Oh yeah? wait till you hear the ABS kick in I have read long ago and
cannot remember where of the problem being solved with noise filters
especially on the fuel pump. It seemed a drastic measure but solved the
poster's problem. I would first look into grounding for everything,
especially antennas. A good solid grounding scheme often cures or
dramatically reduces noise in automotive electronics. I also seriously
doubt that Ford would have installation practices that would cause their
installed factory radio to have noise, most factory systems are quiet. In
other words if it did it from the get go then I suspect something wrong,
like a bad harness ground. If this is the case then your effort will be
futile to reduce the noise in ANY am device.

Please repost your findings, I'll keep thinking. I LOVE automotive
electronics, maybe we can solve your problem!

I will let you know if a solution is found. thanks for your info.
