Another Horn Question

Finally took the time to pull my steering column to see what's the matter with my horn button and wiring. I've got a replacement button and wire but was wondering if the collar is supposed to be this far down on the column. I thought it is supposed to be up where the metal tab on the plastic piece on bottom of the tube grounds it, hence the wear mark around the collar. I believe it was driven down as I kept yanking on the wheel and shaft to pull it out. Looks to be just enough wire to splice into on the collar.

 

It should be up towards the top and should align with the notched opening in the tube.

Thanks. That's what I needed confirmed.

 

Well, I have my horn button rewired, new ground wire from column to horn, and constant 12v power to horn. Maybe it's the horn itself, but I can't get this new wolo horn to blow via button or just grounding it with the wire.

 

You have a multimeter? Check the horn terminals for continuity. A horn is like a buzzer - it makes and breaks connection to move a metal diaphragm like a loudspeaker. There usually is a screw that adjusts the contact and change the tone a little.

But if it does not have continuity to a meter (ie resistance tests large to infinite), it's kaput. Can't have action without a circuit.

 

Most of that type horn are polar sensitive. Are you sure you have the hot wire on the + terminal and ground (button) on the negative/

 

This horn doesn't have +/- marked, but I swapped the wires with no difference. I measured continuity, and it appears this horn must be bad.

 

To double check run a couple jumper wires directly from the battery for both positive and negative to the horn.

You might be beyond this at this point but mine was losing ground though the U-joint on the steering shaft. I installed a nichrome wire with round eye connectors attached to the pinch bolts to ensure a good connection through the u-joint.
