<DIV><FONT size=2>Whilst the other could be an earth problem, it could also
be a 12v supply problem. But there are reasons I won't go into that make a
single fault in either of those an unlikely cause, more likely that
there are two related problems.</FONT></DIV>

<DIV><FONT size=2>The easiest thing is to diagnose the horn circuit, and see
where that takes you. At the horn terminals you should see 12v on
both the purple and purple terminals of the horn, leave all wiring connected to
their terminals. When the horn button is pressed, on a working circuit,
the purple terminal will stay at 12v whereas the purple/black terminal will drop
to zero volts. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>With a non-working horn if the purple drops to zero then the
problem lies back towards the fusebox, bad connections at the fuses and the
spades are not uncommon.</FONT></DIV>

<DIV><FONT size=2>But if both terminals stay at 12v then the problem lies back
towards the horn button.</FONT></DIV>

<DIV dir=ltr data-setdir="false">After this hollow victory I had to use the
horn on the test drive. Now the horn does not work, but when I push on
the steering wheel stalk to activate the horn, the brake warning light comes
on. I just love electrical problems. Not in my element here.
Any ideas?</DIV></DIV></BLOCKQUOTE></BODY></HTML>
