While putting the ColorDMD last night, I came across a new mystery in the backbox that I'm hoping someone can help me decipher. Keep in mind that since fixing the cannons a couple weeks ago, I've got about 60 games on the pin and everything is working (all switches, all solenoids, all lamps but one insert in the Neutral Zone, all modes behaving properly, including Final Frontier, no Credit Dot, no Test Report)
I found two clipped wires that are bundled together in the same wire-wrap by themselves: VIOLET-YELLOW AND VIOLET-BLACK. VIOLET-YELLOW can go to lots of places (50V for solenoids) but I can find reference in the wiring guide docs to only one place for VIOLET-BLACK and that's Solenoid 7 (KNOCKER). When I look at the Knocker, it has VIOLET-BLACK already attached. And it works. And there's a Molex connector for the wires going into the Knocker where one end opposite the Knocker has two VIOLET-YELLOW wires tied together.
Is that Molex connector to the Knocker factory or a hack?
Are there other places in the pin that has a VIOLET-BLACK wire besides the Knocker?
Thanx in advance for any insight....IMG_7848 (resized).jpgIMG_7851 (resized).jpg
