I have searched through many forums and have been unable to find anyone with a similar problem. I am on my third new horn relay from Moss and have been unable to get the horn to work with the new relay. The horn works fine with the old mechanical relay. I have transferred the four wires over from the old relay to the same connectors on the new relay and have double checked the wiring against the wiring diagram. For the first two relays I disconnected the battery and transferred the wires, then reconnected the battery. When I pressed the horn button, the horn came on and stayed on even after I released the horn button. I had to disconnect the battery. After that, when I reconnected the battery, the horn would only click when I pressed the horn button. For the third relay, I left the battery connected, connected the purple wire with two connectors to W1 and C2. When I connected the PY wire to C1, without the PB wire to the horn button connected, the horn sounded. My car is a 1973 TR6.
I notice that for the 70 - 71 models with A type overdrive, this same relay is used for the overdrive, but connected differently from the horn relay. As a horn relay, C1 is used for the load side, while for the overdrive, C2 is used for the load side. For a mechanical relay, I dont think this makes any difference. However, I am wondering if the new relay is solid state and it makes a difference which way around C1 and C2 are connected.
Any help someone can give me would be appreciated. Thanks
