Cord 812 Horn Wiring

We have new horn wires and contacts. There are 2 springs involved under the cap and horn ring. We also have a diagram that comes with the horn contact wire.

First, the steering wheel horn ring cn be removed by removing a screw from the back side of the steering wheel hub. You can then un-screw the the center cap. Be careful because it has a spring behind it, that may be lost. after you remove the cap you can remove the horn ring. You will see a brass end on a wire that snakes through the column tube. This is the ground connection to the horn relay. If you touch this to ground and get a horn output, this is the problem area.

If this doesn't do anything, try making a jumper wire and connecting the negative to the horn wire. You may also want to make a jumper wire from a clean spot on the horn to the positive terminal to make sure the horn has a good ground. This will tell you if your horn or horns are good.

If the horn(s) work, check the horn relay on the firewall (passenger side down low). Make sure the wire from the steering column is making connection, check incoming power connection, and then check output to horns. You may be able to hear a 'click" if the horn relay is working. If the relay is not working, take it out and disassemble, and diagonose off the car with a meter or test light.

This wiring method has been used forever on cars.

We recetnly purchased a Cord 812 Phaeton, and when we took possession of the car everything worked perfectly. We have not done any mechanical work on the car, other than cleaning and detailing for AACA and ACD shows. We try to drive the car every 7-10 days and check on lights, wipers, etc. Last week we were unable to make the horn work. We have checked wiring connections that we can see, but have not taken anything apart, yet. Can anyone point us in the right direction, and where can we find a wiring diagram? How does the horn rim on the steering wheel come off? I imagine we have a ground wire loose, but any advice would be appreciated.
