Hello Jason,
It could well be damp getting in where its not supposed too. Causing the short. I would check the big 30A charging fuse just in front of the battery, then the fuse up by the ECU I think its a 10A maybe different size on your bike. Check the battery with a multimeter, and there is no furring on any connectors then all fuses in the fuse box.
I am sure somebody will be alone with more knowlege with electrics, But thats where I would start.
Good luck hope you get it sorted.
regards
