Find which color wire it is on schematic on the Jones plug and jumper from back of solder side of plug to female return wire. I have seen this a bunch on Jones plugs drives me crazy thinking it’s a broken wire somewhere. That particular male or female pin might be dirty or not tight enough contact
Each of the 5 center rollover buttons will trip a bank relay. A make/break switch on each of these relays will transfer power from the bank relay coil to the 10 point relay when the relay pulls in. Clean and adjust switch if needed.
Update: I have located the wire to the ace relay on the playfield. I've jumped the lugs to bypass the wiring, going from scoring switch to the lug on the relay switch. Nothing happens. I'm wondering if I have an issue with my coil? I don't know why this one coil isn't firing properly. Any ideas?
