Coin Door Wiring

[acevedor2]

I know there are a bunch of threads and I know how to get the coin 1/2 hooked up to the IPAC.  My question is, do I have to send the grounds from the coin mechs back to the ipac as well, or will they work fine just grounded to the cab.

In other words, can i just run the positives from the coin mechs back to their respective ipac ports and then run the grounds to the cab, or do I have to run both positiver and ground from each mech back to the ipac?

Thanks as always!
Cheers!

just try it, its quicker than typing this respond, but I connected the nd to the IPAC.

Just daisy chain the Common terminals (ground), wire them to the IPACs GND terminal and wire each NO (normally open) terminal to the IPACs input terminals (Player 1 coin, Player 2 coin etc)
