Hi,
This seems like a broken wire in the loom that you move, or a wire loose on one of the pins, but Combilift Technical will be able to help you. The quickest way to contact them is to complete a technical support request, no login required and no cost. Go to the web site, www.combilift.com , scroll to the bottom and fill out the "Technical Support" form.
This works worldwide and will be directed to the closest techical support to your location.

Hope this helps
Richard
