It's most likely that the fan relay has failed closed. Sometimes a bad relay will reset if it's knocked around a bit, but I wouldn't trust it. Any standard 12v 30A 4-pin automotive relay should work.

Fan motor is likely on a wire that is hot-at-all-times. THe relay is tripped when the ECU grounds a 12v connection. Less likely that a short to ground has developed in the wire harness, especially since the 12v signal shouldn't even be available with ignition off.

Second generation bikes; the fan(s) are wired up like the starter motor; hot at all times. Have they changed that with third generation?

I'm thinking it's the same? Looks like they even used the same green/yellow color designation for the signal wire that is grounded via ECU.
