Jason, a complete guess on my part. Reading the conversion notes, one loco picks up from the tender, the other from the loco itself, but both rely on the loco-to-tender connection, and there is a cautionary note in the G2A notes re. alignment of the “pins” in the connector. If you’ve had the need to disconnect them, perhaps double-check they’re back as delivered? Good luck sorting it out.
