@tb - Are you sure you have the battery oriented correctly in the box? The positive terminal of the battery should be towards the front of the bike. The battery actually lays on its side, with what you would typically consider the ‘top’ of the battery facing towards the right side of the bike. If you install it with the ‘top’ facing upwards, the polarity of the battery ends up reversed relative to the wiring. This came up in a thread fairly recently, and I recall mention of some kind of an electric noise from under the tank before the main fuse blew.
