One other quick question, regarding the horn in my jag.
I replaced the stock steering wheel with a wooden steering wheel that was from an 85 VDP. The horn button is present, but I guess it was dismantled by the PO when he was prepping it to ship.
The wire under the button is a single yellow wire (thin). How is this supposed to actuate the horn?
THe wire is connected to a spade connector on the bottom of the button. Is this yellow wire supposed to fit into the center of the steering column? I noticed there was a long, narrow cylindrical tube, with a brass insert in the center. I thought the function of the brass tube was to be like a long wire, which would then go to the relay.
I probe tested the relay for voltage, and I was getting voltage at the Brown/Purple wire & the Green wire. Interestingly when i probed the green wire, i got the relay to "click" -- however, still no horn sound :-(
Was it the wheel swap that caused the horns to stop working ?
It helps to have a wiring diagram in these cases, but I am fairly sure the horn button earths the supply, thus switching the horn relay. Horn is always on, regardless of ignition switch position, at least it is in the UK cars.
