Yes it's a quarter I sure I got it in there but I will double check I think I'm having a power issue no power at all to coin or bill
Make sure all of the fuses are ok. And that the power supply is firmly connected.
With the machine turned on if you try to turn the reels by hand do they have a stiffness, or turn easily? If there is a stiffness then that is good, it means they are getting power. If the reels turn easily then there is a power problem, read below:
A common problem on older S+ machine that don't work is a bad power supply connector on the motherboard. The motherboard is the smaller circuit board mounted horizontally in the bottom of the machine. The "mpu" board is the larger board that is mounted vertically and it plugs into the motherboard. The mpu also has the 3.6 volt battery that sometimes needs replacing.
Turn off machine power. Remove the hopper and look on the front edge of the motherboard for a white molex connector with 6 wires. Make sure this connector doesn't have any darkened or burned areas on it. Be sure to check the backside of the connector. With the machine power turned on if you wiggle this connector or slide it up and down a little and the machine comes alive you've found a problem. See photo below.
