A customer bought some CoinUp's to install in some of his games without Free Play options. He read the instruction manual and connected up the Ground pin to the control panel common ground, connected the P1 and P2 Start pins to their prospective "hot" wires, and connected the coin switch pin to one of the coin switch "hot" wires. He then set the dip switches to Enable, 1 coin per play, Normal pulse - didn't work. Tried it on long pulse - didn't work. Called me.
I verified the wiring, shorted it a bit in case of wire resistance, and even connected the +5 pin to +5 (even though the P1 wire measured a good +5.11 that should have been enough to run the little board) - still didn't work. tried another CoinUp with the same result.
What is interesting is that when the +5 wire is connected, the coin counter engages and stays engaged while the coin switch wire is connected. If the +5 wire is not connected, it doesn't. Doesn't work either way. Tried it on both coin switches.
I checked to make sure the coin switch ground and the control panel ground were the same (in case that mattered) and they were. Coin switch works when triggered, and start buttons work when credits are added manually.
So - why is it not working? is there something else - maybe a coin multiplier board like some Pacs and Galagas have - that is keeping it from working? Anyone have any ideas? I go back there in a few days and would like a few things to try...
