UPDATE: PROBLEM SOLVED. I’ve asked about the horns on my 36 before and I’ve made some progress, thanks to the feedback from this group. I’ve finally gotten my horns to work, but not at the right time. When pressing the horn button on the steering wheel, I get nothing. But when I depress the starter button, the horns Blair. This makes it a little embarrassing when starting the car in public, not to mention making it difficult to hear when the motor starts. The car seems to have a new wiring harness. Not sure where to start looking. Could the wires be switched? Bad ground? Bad insulator in the horn button? Any help would be appreciated

Sounds like a wire is on the wrong post. Get a wiring diagram and use it to trace all the wires and connections. Is it a stock wire harness?

Yes, it appears to be stock and newer, but I’ve heard stories of the harness suppliers mixing positions on the wires. I’ll check that out. Thanks

Enclosed is a picture of the 36 Ford wiring diagram. The starter button wiring is missing but it is a direct connection to the starter relay. The button applies a ground through the dash which energizes the starter switch. This works (as your car starts) so that connection is good. This wire should not go anywhere else. The Y(ello) from the battery is directly connected to the horns. The second connection on the horns (BLY goes to the lighting switch at the bottom of the steering column where it is connected by the horn rod to the horn button where it is grounded through the horn column. I can't see where a ground connection to the starter relay would ground the wire to the horn button. Happy hunting.

There seems to be some confusion here. If the car is wired up the way Ford originally made it, there is no instrument panel mounted starter button. On 1936 and earlier Ford passenger cars, the starter is energized by pushing the starter switch located on the floor which provides a direct connection between the starter motor and the battery. With this setup, there is no solenoid nor starter button.

Sounds to me like you have the hot wire to the horn connected to the wrong post on the starter button under the floorboard. It should be connected to the hot side. Pressing the starter switch must be sending current to the starter and to the horn. But if I am correct, the other wire to the horn is permanently grounded, which it should not be. Making me think the contact at the bottom of the steering column isn't releasing or there's a short inside one or both horns. The one lead to the horn from the starter switch is always hot. Pressing the horn button grounds the horn to close the circuit.

fenbach's explanation seems logical to me.

My bad, I assumed the 36 was like a 37. Does the horn button spring back on release, breaking the contact?
