I do not have any experience with roadsters. With that out of the way, how are you proving the windshield switch is operating correctly? Are you checking it in place with the top latched, and then with the top unlatched? Meaning you can check a switch for continuity and not know if it is actually tripping when in the open/closed position (clicked either open or closed when in its respective position). OK, that's my question, hope it helps!
