I just bought a Capt Card. It was my first EM but its working. So if you need to bounce anything off of me let me know. In regards to free play. What they do is connect the credit button to the coin release so that when u push the coin release it acts as a credit. I believe. FredSmython gave you great advice. I would do exactly as he says. Most EM problems are similar to yours. Contacts get worn out switch stacks and relays need adjustments. Good luck and please again let me know if you need anything
