Has anyone ever had to change out an ignition switch? I had an intermittent fault during run up today, it would stay grounded when turned back on. I gave the switch an aggressive recycle and it the functioned normally but would do it once in a while. I noticed it when I shut down the engine, turning off A first the engine died. The wiring at the modules appears ok, nothing disturbed, I'm about 90% assured its the switch. I'm thinking about opening up the avionics bay and spraying switch with contact cleaner but I'm also thinking about replacing both switches but it don't look easy, appears they are soldered in place.
