Ok so I have a jamma cabinet all wired up but I am having problems with monitor wiring. Off the iso transformer are only two wires to power monitor. New monitor has 3 wires. How do I rewire to supply power?
Check your new monitor 3-wire plug. Center wire is most likely green. That is a free ground wire that can be attached to a nut holding the iso down if you wish, or leave it disconnected. Connect the two wires from the iso to the two outer pins of the connector. it doesn't matter which go where...
