Hello everyone,
I'm restoring at Kitac SUPER COP machine, and I have everything working except for a hopper payout. After it records 50 credits and upon the next spin when it should payout, the error code of "AO" appears. The same code appears if no hopper is plugged in. I have cleaned the hopper, plugged and re plugged all the cables several times across the entire machine, and have inspected all the cables and they all appear to be in excellent shape (no mice). The hopper can be manually turned and it will dispense tokens. I've included pictures for you to take a look and see if anything looks out of place.

Any Ideas?

The hopper is a CH-500 by Asahi-Seiko. I would be willing to buy a working hopper if anyone has a spare (see photos for plug type).

Thanks,
