Based on some anomalies I have experienced with my plane I am beginning to suspect I might have a grounding issue.
My rotating beacon/strobe combo stopped working than miraculously began working again.
Stormscope throws antenna fault then miraculously began working again.
Marker beacons not working. They might be working, just not when I need them.
Now the autopilot is wandering on heading. An avtech told me this can be caused by a bad ground.
Anyone know where I should be looking for grounding connections in a PA24-250? I found the engine ground which looks in good shape.
As always, thanks for the help.
