So it had been over two months since I replaced power steering rack,
pump, hoses, alternator with wire harness, and all front suspension
bushings.  Sometimes brutal but successful work.  So today I thought I'd
do something easy, just cuz, like throw in a horn relay.

Result -- no sound on pressing horn ring, very faint tone on releasing
ring. ???  Pulled wires, tested 12 volts on yellow/black.  Replaced
wires from ring directly to horn, eliminating today's relay work.  Horn
acts the same, just the slight tone on releasing horn ring.

Horn was fine before I started this silliness, so how did I kill it?  Or
is there something else to do before just buying a new horn?

Thanks folks,
