[TR] Horn relay questions

 The follow-up question is what voltage do you read on the Purple wire when the horn button is pushed?  There could be a poor connection anywhere in that line and at the fuse itself.  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.
Do the easy stuff first, I always say.  (Sometimes I even follow my advice. ;-) )

Subject: [TR] Horn relay questions  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.
