I was getting ready to have a rego inspection and tested the horn. It had worked up until I was ready for registration. Any way I ended up having to remove the upper column from the car and dismantle it to repair the horn.

The problem was the horn was not working, (in my state the horn MUST be operational for registration). After dismantling the column I could not the hor to work reliably. It was off for only half of the rotation of the column and then on for the other half. I had a short in the column.

The short turned out be the brass collar shorting on the column cover. As the wheel was turned the horn could not be turned off, VERY annoying. I wrapped the brass collar in tape and you could see where it was rubbing, so the clearance was less than the thickness of electrical tape.

For anyone who has this problem here is how I solved it.

This required the total dismantle of the column. The ROM is clear and was helpful in the removal of the column and ignition from the column, so I won't go into this too much, suffice to say I used a dremel to cut slots in the screws so I could re-install them.

Column removed and inner column out. The brass collar was my problem. The spring touches the long pin and the collar. I made a new collar from a 1" copper pipe joiner, I had to bore the inside a little in the lathe so it was a snug slip fit on the insulation tape I wrapped around the column.

I cut the black plastic thing to keep the spring pin into the column hole. then wrapped in electrical tape inserted the spring and fit the new copper collar. I used 50mm and 24mm heatshrink to hold the copper collar in place. this heatrshrink has glue on the inside so everything is held in place.
