@ted K posted:... i turned over the Atlas controller and banged each of the hex nuts so they would go further into the body of the connector - then i tried a thin spade connector and it slipped in fine and i was able to tighten each of the screws - the manufacturing of the connector did not "drive" the nuts far enough in the body of the connector to enable the screw to have room for a wire or a spade connector.
Did you try this.
