Question
hello i recently obtained a slot machine. it is a bally 742a-401 number 16375. wondering if you know anything about it. i can power it up and the hopper starts spinning and wont stop until i am assuming it times out and i have to push the reset button inside behind the hopper to get the machine to come on again, but in the meantime it is like everything else is shut down. it wont accept coins and i cant pull the handle and i dont know how to get to a point where i can put a coin in and try it out. i dont have a picture at this time as i am at work right now but any information you have would be greatly appreciated.

Answer
Hi Brian,

It sounds like to me that it needs to finish a payout, have you tried dumping some coins in the hopper first? Or change the position of the reels to a none payout combination first, before you plug it in. When you get a winning combination on this slot machine, it completes a circuit that ends up on the contact board on the back of the coin hopper. This provides the hopper with a scorch of hopper motor power, and off it goes, The spiro cam on the back of the hopper gets stepped up once time for each coin that passes under the hopper coin counter. Once the spiro cam steps off the hot trace, (the 10 coin trace if it's a 10 coin payout) then the power source for the hopper motor is cut off and it stops running. So, on yours this spiro cam is not stepping up, could be that the hopper has no coins in it.
Let me know OK?

Thank You
