Once I got an intermitent short on my alt able to get between 18 up to 24 volts depending on RPMs... but without load, so I disconected the batt and engine died. It was one of the rotor vent vanes getting in touch with one of the stator leads on every spin.

BUT... the engine never increased the RPMs by itself. Just sharing one misterious experience I had
