I have power at the N/G bullets and connectors. When the N/G wires are attached to the horn connectors, I get power at the N/B wires. When the horn button is pressed, all wired up this way, I very low “hmph” or “bump” is heard. If I remove a N/B from a horn and touch it to ground, the horn sounds as it should. If I remove the other N/B and touch it to ground, again the horn sounds as it should. I am guessing the horn button ground is not doing its job. Now, to trace where that ground connection is located. Does that logic make sense?
