Leader Megatron Electronic Help

I had a leader Megatron back in july. I transformed him once and the electornics went kaput. Replaced the batteries, but I figured somewhere along the way (considering the batteries are in the tail, the the electronics are 4 hinges away) the wires broke. I finally got a new one a few weeks ago but now I am afraid of transforming him and loosing the lights and sounds.
Has anyone had this problem, or am I being paranoid. Is there anything I can do?
