Roadster Turn Signal Switch
switch that has been tested and works fine. Copper
strip that engages steering wheel so horn will work
was partially broken off. (See Arrows in Picture).
Worked in car it was in; owner solved problem of
having to solder the tiny wire on another contact
strip by just laying a good contact strip OVER the old
one so they connect to each other and operate horn.
Correct way is to of course solder the old wire on to
the replacement contact strip; but the fellow probably
was at bad at soldering as I am and solved the problem
