GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
We've checked the resistor and it gives 50 ohms, as for the voltage since it was marine we are assuming 12 volt, but it could be 6 or 24 as well. AC is something we've been thinking about, to vibrate the disc back and forth.
We hooked it up to my car battery and tested each end. I was hoping that we'd hear the thunk and just have to adjust the nut on top to get the horn to go, but I think I'll take the electrical apart and go through everything. It's been at least a couple decades since it's worked.
I recently bought a bronze horn from a fellow who said it came off of our local Coast Guard station in Bay City, Ore. I can't find any information on it, and I'd like to get it working. I'm hoping somebody will recognize the manufacturer.
