Quoted from zaza:
The 'mark' switch closed indicates that the coil is allowed to fire, so yes, it does influence.
Agreed, in test the game ignores logic at that point to allow the testing of the coil from anywhere, I think, I seem to recall it firing from the home position in test. In game play it will not fire if "MARK" (SW 32) is not closed while the cannon swings out to the playfield. It could be as simple as a bent switch bracket keeping the actuator from closing the switch, a loose wire on the switch leg, or you have a switch(5647-12693-06) that is just flaky.
