After engine start, both mags show normal rpm drop during mag check. After a flight, prior to shutting down, I always check the mags to ensure they actually will turn off. The left mag operates normally but the right mag will not turn off.
Shut engine down with the mixture control. Hangar the aircraft with a “Live Prop” warning sign on the prop.
Next morning, start engine, mag check shows both mags again working normally. Apparently, when the mag gets warm, it won’t shut off.
Checked all the wiring, replaced the switch etc but no fix. My engine guy suspects something internally wrong with mag. He suggests I pull it and bring it to his shop for inspection.
Before I do that, has anyone experienced a similar issue?
