Repairs Cub Cadet Pro Z 100 blowing fuse after Drive Belt replacement

Has anyone else had a problem with the Pro Z 100 blowing the main fuse when you turn the ignition key? We replaced the drive belt and now when you turn the key it blows the main fuse! We have tried everything and have looked for an bare wires or pinched wires hitting the frame with no luck. Any ideas?

Is the battery hooked up right way around ?
