Since this seems to be an out of warranty issue, you might contact Harlan Flagg at
https://hollywoodelectrics.com/contacts/, he might even be in your area for PPIHC. He would be a potential resource for getting your existing one repaired, though you would likely need to remove/install it your self. The also have an aftermarket charger that could reduce your charge times to about an hour they designed for the Zero that could be adapted.
Another option is Victory owns a 2014 Empluse R that is sitting at Indian Motorcycle of Orange County
http://www.indianmotorcycleorangecounty.com/ that has a bad motor controller, but a working charger that you need. The connectors were changed when the went to the Empluse TT, but as far as I am aware, the 2013 and 2014 have mostly interchangeable parts, including the charger. Talk to Chris and see if he is able to get Victory to release the part to swap out yours.
I would also start calling Victory every couple of days. Expect to wait on hold for 30 minutes and most of the time you won't be able to talk to the person assigned to your incident, but they do add the notes to the case file each time you call. Mornings had shorter wait times when I had to go through this.
Good luck, I hope you are able to find a solution soon.
