Quoted from Jlescher19:I Don't know the diff between a rotary and normal trip bank but
It's on the solenoid reset bank on the left bottom center.
Here is a pic of the rotary style in my Rocket III, Bally call this the "Motorized Trip Relay Bank" in the parts catalog. Just as cactusjack describes in this machine the left hand spindle of 6 Relays controls feature lights in game, and the right hand 3 are on an indenpendant spindle for start and reset functions. The reset motor is just out of shot to the left.
