It is a panel mount, not vertical, from Vans. There is nothing really near it that carries substantial current, just a G meter and the VOR indicator head. A Garmin 430 is about 8 inches away. I have all of my fuses/breakers on the side panels so the main panel has little on it with current flow. Could the rollover hoop be magnitized? If it is, why doesn't the compass show a constant error rather than swinging? Or could the (Chinese) compass just be junk?

This solved my compass error problem. After degaussing the compass error correction screws were enough to zero out all remaining error. If you do this make sure you take out all panel electronics first, including CDI heads and such.
