Hi folks hope someone can give me a littel insight on my problem.
cobra 29 ltd nw classic its in a 2007 Ford sterling dump truck with a detroit diesel engine .
I put a ground strap from mirror to door frame a 15amp noise suppressor in line to cb and a power line to batterys.
When the key is in the run poss. i get a loud static up to 3 on the metter cant hear that fare ,when the key is in the off or ass spot it is great i can hear far away.
When the engine is running the nois level stays the same...
Any help would be great thank s
Static when key is on engin is not running help.

It sounds like either computer noise or electric fuel pump noise.
If it is computer noise, well, your pretty much stuck with it, but if it is fuel pump noise you may be able to get it sorted.
You may need to ask your local vehicle distributor if they have a noise suppressor kit for the fuel pump.
If you can find the power supply to the pump you could try unplugging it, to confirm that it is indeed the issue.

Thank you for the reply had the same kind of thought it has no fuel pump so thats out I was hoping it was not the computer , it does have almost like stepper motors running the gages noise starts when they go on line and start moving I was thinking about taking fuses out one at a time and see what happens thanks all

If this is comming in through the power and not the antenna you may want to try this http://n4maa.us/alternator.htm I found it to work on several different interferences.
