Hello Jacques and Chris,
Thank you for the directional information and with a bit more YouTube information, I was able to get started. I disassembled the horn further and I checked the continuity of the resistor and the armature, both were good. I cleaned and adjusted the contacts and then I applied some power. First was a small 6V lantern battery but it didn't have enough amps. I tried a bigger 6V battery from the truck and all it did was start to smoke the resistor. I finally tried a 12V battery on the off chance and it started to smoke the resistor as well. The diaphragm moves up and down with my fingers but it appears that the armature might be pooched. Unfortunately, this is not a mission critical component so I have parked it off to the side now. Back into the points, condenser and distributor timing.
