Hey all! FIRST POST EVER! Excited to be joining the pinball community it’s fun and I’ve been learning a lot. Just inherited an Evel Knievel SS commercial pinball machine. I have a few flaky lamp sockets I’m trying to change which were one lead sockets. I bought 2-lead sockets to replace them as I couldn’t find any one-lead sockets, but I can’t get them to light up the bulb (#44). Below is a pic of a working socket (red wire) and a replaced socket that I don’t know how to wire (green wire). The light coming through is the sun, not the bulb lighting up. Also, I have a bad diode on the Credit switch and I want to replace it but I’m not sure which diode to replace it with. The wiring diagram shows the diode as IN4004 but not sure what that means! Pictures below. Thanks for the help and take it easy on me!

Also, how do I reset the credits on this thing!?!?!

Quench, thank you for taking the time to help me!
