(2nd attempt at posting this question—apologies if there’s a duplicate somewhere)
Hello! I’m hoping to tap into the collective wisdom on this board to get the horns on my ’37 to function properly. They worked well until recently, but I don’t think there was a specific incident that did them in—at least not one that I’m aware of. When I press the horn button, both horns make a clicking sound, but if I wire them directly to the battery they blast away. The wires are delivering a full six volts to the horn, but clearly not with enough oomph. The wiring in question is either original or very old and comes out of a cloth-bound harness. The lights, also in that harness, work perfectly. I suspect that the only solution is to replace the whole length of wire from the horn to the button, but I don’t want to go to all that trouble without proving that it isn’t something else. The battery is in good condition, fwiw.

The manual for the car is spectacularly unhelpful, though it has a section on the horns: “The horn requires no lubrication and should require but little attention.” Any help sincerely appreciated.
