Ok here is my issue. I have a 06 340DA and installed a brand new Simrad 4G system. I am getting interference with the radar. So after a whole bunch of troubleshooting here is where I am at. The moment I turn on the key or push my starter switch one click I get the interference and it continues once you start the motors. I have ruled out the boats electrical system buy running all 3 power and grounds to a separate battery that I brought aboard for testing and fused everything. I also ruled out the radar cable as I pulled it completely so its not running near anything with electricity in it. So there must be something that when you push the starter button one click that starts to emit some sort of RF that the radar picks up. I disconnected the fuel pump so that wont start and still it persists. Can anyone tell me what is powered up once the start button is pushed? There must be something getting power that is sending out the stray signal and I need to figure out what it is. Been working on this for a while and its driving me nuts. Top pic is start button one click bottom is off.
