RV-4 Compass Help

Well Known Member
I have a problem getting any good compass information in my RV-4. The panel is loaded with clocks. Until recently I had a remote compass, but I removed it so that I could install a Narco Nav 122. My compass is just over 90 degrees off. No luck with adjustments either.

Anyone have any thoughts or ideas?

Thanks!
 
mu metal is a magnetic shield, so you cannot wrap your compass in it.
Is the compass off by 90 degrees with the power off? If so you are close to something magnetic. Find it with a small portable compass, and de-gauss it or shield it with the mu metal. If the compass error is a power-on problem, find the wire(s) causing the problem and move it, and/or wrap it.
