I am curious... how does one determine that a bendix is "...almost
engaged" or "...partially (engaged)"?

I have a customer with a pair of factory reman IO 540s with less than 100 hours
on them. After landing he will sometimes find the bendix drives on the
starters partially and occasionally fully engaged. It does not happen every
flight but sometimes every other flight. On at least two occasions the bendix
drives were not engaged after shut down but were almost engaged when the pilot
returned from lunch an hour later!
..........
Is is possible some kind of transient voltage
spike at shut down is attempting to drive the starter? Why would an unengaged
bendix become engaged while the aircraft is shut down and the crew is at lunch?
