D20, did you figure out your points cover yet? I had the same issues with mine. It was the connectors on the end of the blue & yellow wires that were hitting the cover.
You need to change the position of the wire/connector where it connects to the bottom of the actual points assembly. Just undo the screws where the wire attaches, like if you were changing the points, and turn/flip them (however necessary) so that the connector is not hitting the cover.
