I have a Pacman Machine where the Coin counter doesn't count.
I've connected the 2 leads to Pin 5 (7.5 V) and Pin 7.
I've also tried reversing the two leads and that changes nothing.
Also I hooked it up to a 9V battery and it works fine.
Any help would be apreciated.

Well looking at the schematics, I guess you need to check that Q3 is getting a coin in signal. If it's not Pin 7 will never go to ground.
