Holy crap, Nic! Seems like the main fuse got busted. If I knew you'd try turning the key to the left, I'd say NO because turning the key to the left lights up all signals, and we know that there is a short somewhere in the signal circuitry. I am guessing that because the ignition wasn't ON, the only fuse deployed in such key position would be the main fuse, and that's why it blew. I'd say the tail needs to come off, as well as the left fairing, and the tank needs to be propped up. Then tracing wires, unplugging the rear end, and looking for pinched/exposed wires/connectors in the tail section.
