Only thing I've tried was a malfunctioning alternator in the Piper 28.
Light came on shortly after departure, and the first thought was..... "hmm what's that light? Never seen that lit in flight before?".... second was "oh, alternator.... that's not dangerous, or require immidiate "we're gonna die if I don't do anything"-attention and can be done using the checklist"....
The checklist made me laugh (within, I had passengers onboard).... 2 items....
But we ended up flying home without alternator, and a reduced load on the electrical system. An inspection faound the "coal"-pieces to be worn beyond use.
