I am having a problem with a PW ZW. The L shaped bracket in the photo below (has a black wire attached to it) moves when you operate the handle causing the edge of the bracket to rotate and touch the transformers' metal frame and short out. I've had this ZW for many years and it has always operated great. It is as if this L bracket piece is supposed to be stationary and not move with the handle. I hope my explanation of the problem, and the photo makes sense.
Thanks,
Ed
