<DIV>Hi<FONT size=2>,</FONT></DIV>
<DIV><FONT size=2>I think there is a misunderstanding of how the TR4 and TR4A
horn contacts work.</FONT></DIV>
<DIV><FONT size=2>The steering shaft is the ground.</FONT></DIV>
<DIV><FONT size=2>The flat brass ring is what the telescopic spring loaded
contact rides on while pushing against the horn button brass
contact.</FONT></DIV>
<DIV><FONT size=2>The two silver colored tags shown in your photograph are
simply there to secure the non-conductive base, for the brass ring, which is
wired to he horns.</FONT></DIV>
<DIV><FONT size=2>Regards,</FONT></DIV>

also pushed the steering wheel laterally just a bit to the left towards the
driver?s door, or to the right towards the passenger door, contact would be
made and the horn would sound. And it worked consistently ? it still
does.<BR><BR>If nothing else is fixing it, try the left or right push. Having
the engine on helps.<BR><BR>I?ll take this opportunity to ask my own question:
does anyone have a recommendation for how to improve the contact
?permanently?? Something like a silver conductive epoxy? If the contacts were
maybe a millimeter larger in the direction of the steering column, the
left/right push probably wouldn?t be necessary.<BR><BR>One other thing:
sometimes the circuit would complete ? you could see it on the ammeter, but
still no horn. That took a turn or two on the adjustment screws on each of the
horns.<BR><BR>--Greg</BLOCKQUOTE></DIV></FONT>
