without reading that link my guess would be that the motor is rusted and either locked up or almost locked up to the point that a ton of current is needed to make it turn.

well,that link has everything i needed.according to it ,the black box is cooked. that said,the whole sytem looks perfect and like new.no moisture or water on anything . it works but blows the fuse after a couple of movements. it actually seems like a complicated system to just make a little electric motor move up and down. anyway,thanks alot for the help. now.... where do i find a black box?
