<DIV>Clausager and BL documents imply that the UK only had twin horns from
1970, North America with the Mk2. Originally there was a sub-harness from
the right-hand to the left-hand horn, the main harness probably contained
the wiring for both from 1970. It/they moved from the slam panel to the
inner wing in 1963.</DIV>
<DIV> </DIV>
<DIV>The earth path to the horn push is pretty awful, no allowance for
electrical conductivity in the chassis/crossmember/rack/UJ/column assembly
unlike a pal's TR4 that has a braided strap from the chassis to the rack and
another round the UJ. In which case a PO may have removed the 2nd horn as
it would double the load and make things even worse if connections are
weak. My V8 came to me with a single moped horn, I had to add a relay
before the correct horns would work at all even one. Subsequently I had to
add one to the roadster as well. The standard horns with good electrical
conductivity are pretty powerful.</DIV>
<DIV> </DIV>
<DIV>If you put a voltmeter between the purple terminal at the horns and
the body and push the button you will see how much voltage you are losing
through the fuse (if any) by the voltage dropping from 12v. Do the same on
the purple/black and the higher that is above zero shows how much you are losing
through the earth path.</DIV>

<DIV>Speaking of horns, my 1969 MGB GT has only one horn. Is that
original? It has two wires going to it. It works OK, but it just
sounds weak. What is a good alternative? Can I wire two horns
here?</DIV>
