[TR] Horn relay questions

[Jeff Scarbrough]

If you can disassemble the horn, you should be able to disassemble the
relay.  Try cleaning the points in it.  What have you got to lose?

The relay is only operating intermittently now and I am pretty confident it is toes up. I’ve cleaned all of the contacts and tested the horns with direct power. One worked well and I had to disassemble the high tone. Cleaned the points and it appears to be operational now. I’m going to do a bit of cleanup and reassemble it this morning. I’m relatively confident that a new relay will get me done with this little project. Regards,

Try disconnection and reconnecting everything (that is convenient) in that circuit.  This will scrape off some of the accumulated corrosion and can make things work again.

> I have a 5 pin horn relay on my 1976 TR6 that appears to be original.  I am only getting 9 volts on the purple/yellow output to the horns so I am assuming a bad relay, but I cannot find the purpose of the 5th pin.  It is not the horn ground from the push button, input from the fuse box or output to the horns.  My wiring diagrams all show only 4 pins for the relay.  I cannot read the pin identifiers so there is no help there.  The wire is black with a tracer color that is faded so I cannot determine what it is.  Any ideas would be appreciated.
