The routing plug is missing mate, that's why everything is diverting to the hopper.
It should be in the hole to the left of the one which has the wire in, in pic 2.
Has it fallen out into the machine somewhere? It's a black plastic plug with 22 holes in it.
If you find it, put it back in and it should work properly (as long as it's wired up correctly)
If you can't find it, I might have a spare, but I'd need to know which exit the quids come out of to go into the hopper, and also which exit you need the overflow coins to go to...... ie which cashbox in the bottom, usual practice is that quids go to one box and all other coins to the other.
If you look at the mech from the top and from the front, there are 4 exits in a sort of square, so as you're looking at it, the exits are
D C
A B
Hope you can understand that ![:)](https://www.fruit-emu.com/forums/public/style_emoticons/default/smile.gif)
