Hi All
I'm new in this forum: I'be bought a Space Invaders and I need your help for solving an issue.
Game switches on correctly but If I try to load credit (touching directly metal lever on the coin meter), but it doesn't work.
I checked with my DMM the voltage of the two wires (measured between each wire and ground) connected to the coin switch: 0V (DC).
How is the correct voltage I have to see here?
I have electric diagram of CPU board, but I don't see "TP"s (check point) voltage, and also supply voltage on CPU board connectors.
Any help would be appreciated.
Thanks in advance!
