I do believe this is a first on the C-14, or at least the first time I have heard of it.
No real idea as to what may have been damaged but as an overall statement, individual electronics packages, such as the instrument panel (the digital display part), the ECU's and so forth are <usually> protected against reverse polarity because sooner or later, it will happen. Maybe not the way you happen to have it happen but when wire bundles are cut or chafed through, all kinds of cross- current takes place. So I would be quite hopeful that your damage is limited to very specific areas of [not overly expensive] parts.
As Rich said, check the main fuse behind the battery, attached to the starter solenoid. It is a 30 amp mini- fuse, sealed in a waterproof fuze holder and there is a new, spare fuse next to it. If that fuse has popped, that along may be your entire problem. If not, you are going to have to get a voltmeter and start chasing wires to see where the voltage "is not" so you can find your additional problem(s).
As far as the dealer, yep, it might get somewhat expensive, depending on where and how extensive the damage is. As far as the embarrassment, I would ignore that- ever see videos of the original Redstone project? Dem Dare guize could not get a rocket, essentially a copy of a pretty reliable German V2, to fly to save their lives. And get this, they really were rocket scientists! So don't beat on yourself about this, most of us have made bigger mistakes than reversing the polarity of the battery.
We may be able to help you troubleshoot this situation if the main fuze is not the problem and you want to tinker around with it yourself but am unsure what to do. Several of us have schematics and can guide you, at least roughly (but safely) in a step- by- step process.
Best of luck with the bike.

I have a 2008 Concourse 14 ABS. I installed a new battery that had the poles reversed. Yes, I do feel really stupid. I heard a soft humming coming from inside the battery housing. I pulled out the battery, saw my mistake, cursed softly, returned the battery, bought the correct battery and installed it correctly. The key in the key pass will not turn to the on position. So. How much damage did I do? Which fuses do I check first? Can I get to the correct fuse box easily? I would prefer not to take this to the shop where I will be laughed at and then charged a Bazillion dollars. Please help!
