I've got my original Delco Remy horn mounted on the intake manifold to sound on my '49 Chevrolet 1/2 ton. Questions: How much spark should I see from the points? I have a slight spark from the points right now. What should the air gap be between the diaphragm and front plate? The front plate is about 1/16" from the diaphragm at this point. Anyone have the specifications for setting the proper point setting and air gap on these horns?

At one point I hooked mine up to a battery charger. The pulsing DC from the charger caused the horn to work after a fashion. This gave me hope because I could make it come alive. I then experimented with the point adjustment.

Thanks guys! I GOT IT. Adjusted the points with a multimeter. Set it to ohms, placed probes on the positive and negative terminals and got the points set at 0.5 - 0.8 ohms and the sound is GREAT!!
