After a couple of weeks of airplane downtime (we went to a birthday party in England via commercial transportation), my StrikeFinder lights up all the time now. Troubleshooting demonstrates that shutting down the alternator stops the apparent sparks. The problem persists after five hours of flying now.

Is it most likely that my Ford alternator's brushes didn't like the hiatus, or coincidentally developed a problem? I've got a solid state regulator, PlanePower, so I don't envision it's causing the sparking.

I had 2 stator leads broken on a Plane Power alternator that made my GTN 650 comm trip off on it’s VPX circuit. Hard to believe that happened as the aircraft sat, but it does sound like electrical “noise”
