Good day - a couple of questions for you. Have you verified battery voltage at the card? Verify that control voltage is present from positive to negative as well. If so have you checked the safety switches and dead man pedal? You can perform a 2-3 bypass on the card to eliminate any safety issues from engaging the contactors. From my experience with these crowns if its not a safety switch or another small problem it is usually a 2 rec?
Hope this helps
