08 Expy - Electrical Noise in audio system
Just installed a Ham Radio in my 08 Expy. I built a filter to remove alternator whine. It works well.
On the other hand, I get terrible electrical noise for 10 seconds if I:
Put the key in the ignition
Open a door
Close a door
It's obviously computer related, I assume.
The computer sees the key has been inserted and starts checking the key to see if it's the correct coded key.
The computer sees the door has been opened/closed and needs to keep the interior light son for X period of time.
After 10 seconds the electrical noise completely goes away.
Any ideas what device might cause this any what wires might need a ferrite bead installed? I hate to go placing ferrite beads everywhere cause I'd probably have to have 100 on hand to cover everything.
Was hoping someone else might have run into this.
