Dear Dave,
I just acquired a Sigma Inc., Deuces Wild Poker Machine. When I turn it on, I get a prompt that says, "Hopper Jammed." I unplugged the hopper and removed it. Noticed a solenoid under the hopper coin holder. Assumed the button on the solenoid switch needed to be depressed by the weight of enough coins in the hopper to allow payouts. Adjusted the contact screw. Reset the machine. Loaded coins. Button pressed. Still no luck. Any ideas?
