I've got some original Hella horns, original equipment on the car, but they've been silent for 30 odd years. Putting 12 volts across the lugs doesn't do anything.
Modern replacements look all shiny and new, even though it's something nobody else will likely ever see I thought I'd try to bring the originals back to life.  Opening them up they actually look pretty good.   I don't see any broken wires, and the corrosion is minimal. The sprung contact points on the right don't seem to be connected in a way that would allow the thing to move in response to the magnet. Anybody know what I'm looking at here? Any particular diagnostics I can do? |

What are you using for a power source? I haven't messed with my original horn, but when I hooked up my brand new Hella Sharptones to a 12v, 3 amp power supply, I got nothing. When I hooked them to a charged car battery, they about broke my eardrums. I just needed more current to get them moving. Not sure if that applies to the old horns.
