I will placing a magnetometer, LED Navigation lights, and LED Strobe Lights in my wings. Is it common and necessary to separate the Magnetometer wire bundle from all other wiring or can all of these be run together in one bundle?

Brooks,
I don't know the specifics of what you are doing but here are a couple of thoughts which might guide you:
  • Follow the manufacturers' recommendations for wiring.
  • Magnetometers need to be installed away from anything which has a magnetic field (steel and iron and magnets in things like servo motors). Their wiring is not particularly sensitive.
  • The wiring for strobes, even LED strobes, may require shielding. Follow the manufacturers' recommendations. (Did I say that already? 😎)
In my Bede BD-4C, I put the magnetometer in the fuselage, far away from everything. The strobes are in the wingtips. There are no lights near the magnetometer.

I don't know about "common" but I would test it before you get things bundled up too tightly. Closely follow the manufacturer's recommendations on shielding and if they have diagnostics, use them. I had a lot of trouble with my LED strobes interfering with the magnetometer even though my magnetometer is in the tail. My plane was built with standard Whelen strobes and I replaced those with Aveo LED. I imagined LEDs would be electrically quieter but they're not. When I installed the magnetometer I ended up having to replace all the strobe wire and being very careful to make sure everything was securely grounded as the manufacturers said to. The magnetometer still registers every pulse but it's within allowable tolerances now.
