Eyes
Last time I lubed my Ion... afterwards the eyes werent working and gun would dry fire when it shouldnt have done. Took it apart again and I'd accidently pulled the eye cable off where it connects to the circuit board.
It was subtle and wasn't readily apparent..
As James states.. have a bloody good look inside your ion and see if anything is amiss.
