From your description you're getting a short in the cables that run through the clutches (hinges) you may have to replace the cables, or, you might be able to use silicone or some other insulator to repair the cut or nick to the cable that cause this. Another possibility is you might be creating strain on the connector from improper routing (reassembly) if the machine has been worked on by a DIYer.
