I think I killed my horn

Chassis - Horn Installation
After painstakingly refinishing the original horn I'm sorry to say I think I made a huge mistake. Prior to installing the horn assembly back on to the bike, I wanted to make sure it was operating properly. I attached the contacts directly to the 6V battery. After a few squeaks from the unit it sounds no more!
According to the electrical diagram there doesn't appear to be any step down of voltage to the unit so its either that it received too many amps or a mismatch of polarity fried one of the coils. I didn't think that polarity was an issue here since its a very simple magnetic coil and field system and it should work in either direction.
After inspecting the electrical schematic closer I noticed that a I installed the horn leads from the bike on the wrong terminals. I'm praying that it is something as simple as polarity and I wont have to purchase a repro horn.
I have a feeling though that this isn't the case and I just put this vintage part into an early grave.
