Got the horns all fixed and painted. Dave had mentioned that they were the original date coded set but non-functional. HA!
The key to fixing non-working horns is to get Jersey Mad at them. First remove the tiny adjuster screw on the side...and not lose it...then spray PB-Blaster or WD-40 inside the tiny hole. Let it soak for a few minutes and reinstall the tiny screw. Then apply positive 12 volts to the horn terminal and negative to the ground bracket and "carefully" whap the heck out of them a couple times against a block of wood on the floor. It will make some weird, dog howl-inducing noises and then you will hear that they are working again fully. It's kind of like jumpstarting Frankenstein's monster. Start with 2 amps, then go to 10 and then higher if your charger has the setting. It's always worked for me in the past and worked on this set as well.
Here's the set all painted up. You can see the date codes on the outer lip One was "37 9" and the other was "39 9". You can also see the "HI" and "LO" indicated on the outer edge area.
