[Mobile-Portable] Injector Noise Cures

[N1KHB at aol.com]

Hi Randy,
   I was given to understand that the new computer  module would have been 
at least $600 at the time. I can't speak for the  present, but back then 
they were really good to me. I don't have a Ford product  now, but if I did I 
would still be willing to give them a shot. They're nearby  as well, so ... 
Geez that was a nice car. Too bad they stopped making  them.

Sonny ,  I have already made a major copper foil and tape purchase. And 
they are proud  of that stuff ! Fantastic about your dealer. Well , This is a 
2000 Ford  Excursion Em Comm vehicle I picked up from the Red Cross and not 
in warranty.  But I will give my dealer a call. Cant hurt. I read in a 
magazine that those  vehicle computers are very expensive to replace. You should 
stay with that  dealer. Service like that is rare today. Thanks , Randy N5WV

Hi Randy,  
Don't bother with copper foil until you try aluminum first. If aluminum  
helps then that will be a clue that you're headed in the right direction  
and at far less expense. 
ARRL can be helpful, and I also found my Ford  dealer to be VERY helpful 
with my HF installation. They even went out of  their way to replace the 
engine computer under warranty to a known (to  them) quieter version. 

Best, 
Sonny N1KHB

Group , Has anyone had much  success defeating injector noise with Ford 6.0 
and 7.3 ltr diesel engines  ? I have bonded the exhaust system , doors and 
hood of my Excursions plus  added extra engine ground straps and power 
directly from batteries and  injector noise is still present. And have 
added mix 
31 toroids on every  power lead and coaxial cable . I have purchased copper 
foil and copper  tape for shielding injector wiring harnesses outside of 
the 
engine and  have not had the time to do it yet. I thought about snap 
beading the  injector leads but they are enclosed under the valve covers 
with 
other  parts in the way. And they are very tight with no slack at all. So 
if it  
was worth pulling the valve covers and oil rails one could not wrap the  
bead at all. For now , all I know to do next is start shielding external  
wiring harnesses with copper foil and copper tape. Anyone have any other  
ideas ?
