>Can a ground path generate enough EMF to adversely affect a magnetometer? I had
planned to use the upper longerons as the ground path for the elevator trim
and tail strobe/position light wiring, but I'm mounting the Dynon Skyview ADAHRS
on a bracket bridging the longerons, bringing the two in close proximity.
Makes me wonder if I would be better off running separate ground wires.

Hi Stan,
Always run separate ground wires. I never depend on the airframe for grounding
anything. I bring all of the ground wires up to a single point behind the panel.
I ZERO and I mean ZERO alternator noise in my headphones.

I mounted my Dynon Magomenter/AHRS right behind the elevator bellcrank on the RV-6.
The compass swings a far amount when I move the elevator though full-throws.
In contrast, in the RV-8, I mounted the magnometers under the vertical fin
and had no problems with erroneous movements or alignment.
