[Mobile-Portable] Injector Noise Cures

[N5WV]

Sonny , I read where one cost a couple of grand ! The Ford Excursion is a 3/4 ton truck frame "F-250" with a SUV atop it. Its my favorite vehicle of any that I have owned. I got 350K miles out of a 2003 model with the 6.0 diesel. I liked it so much I bought one of the last ones made in 2005. I just wish the 2000 model that I got from the Red Cross had the more powerful 6.0 engine in it. You can tell the difference in the 50 hp difference. I really hate they stopped producing it. I drove the Expedition XL and its nothing like the Excursion. Much more room in the Excursion for radio equipment. Two Batteries , etc. Have a good week , Randy N5WV

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 ?
