That’s probably the Pilot relay. Once you dig it out from the drive it doesn’t feel like a great idea to replace it and bury it back in there. I add a base and a KUP relay rather than replace the old. Based on which relays you said you replaced and the fact that P2 was picking, I would bet on the P or NTS relay contacts on the relay interface board. Or a U or D contact if it was directional. But you didn’t notice if the ENA and CO LEDs on the Relay Pilot board were lighting?
