I put a needle compass under the clear plastic on top of my tank bag. The needle was pointing to North just fine. I turned on the electrical on the bike. No needle deflection. I started the bike. No needle deflection. I revved up the engine to 4K rpms. No needle deflection. So, I figured all was OK. Then, I took her out for a ride, and as soon as I got on the highway I noticed that the compass needle was spinning around and around. It kept that up for the whole ride.
I can't figure out why it's doing that. The electric field generated by the bike shouldn't be any different on the road than it is in the garage. I mean, with the same engine speed. So, what's happening?
Do any of y'all have a compass on your bike? And if so, what kind is it, and how well does it work?
