Namco Crisis Zone - Gun shaker motor voltage

[Arcade-Projects]

Hey everyone-

I’ve got a Namco Crisis Zone uzi that I am trying to wire up. Inside there is a shaker motor to provide the force feedback. Looking at the schematic (attached), it is not clear what the exact input voltage is.

I see there is an 18v transformer, presumably 18v AC. The voltage enters a bridge rectifier and then gets smoothed out by a 22,000uF super cap. I am *guessing* the motor runs on ~18v DC (unregulated). Before I fry a rather expensive motor, I wanted to see if anyone knows the voltage, or has a cabinet they can take a measurement from.

thanks for any help!
