I was told when I started on museum aircraft that there was a problem with the Wright powered aircraft, where if a relay stuck on, with GPU applied the starter would turn and as a result the prop would turn.

One day I powered up our Neptune and as the plug went in, the starter engaged. Fortunately on the L/H side where the GPU plug is,so it was obvious immediately.

The other Wright aircraft in our fleet needed power to be selected on the F/Es panel but it was possible with that as well. It took me quite a bit of arguing to convince the others on site that this was a real threat.
