Hello to all,
A quick update on my 1 good and 3 bad horns. Thanks to Randall I now have 4
good horns. So I will share my slow first repair (about 1/2 hour) and the next
two in 15 minutes. Here's the down and dirty. Don't follow the handbook,
you'll just waste time. Go right to the two nuts holding down the points.
Loosen them up, but don't take them off. This move saves the misplacement of
pieces on the reverse procedure. (don't ask how I know) Now gently lift the
top points up at the end while you lift out the pin with a pair of needle nose
pliers. Wipe it down and clean with electronic parts cleaner. (removes the
gummy substance - old grease) Cut a small piece of 600 grit sandpaper. Spray
some electronic cleaner in the hole. Roll the paper so it will fit in the hole
and rotate it to clean the walls. Spray again with cleaner and dry. While the
pin is out run the 600 grit against the points to clean them. Apply some white
grease in the hole and on the pin. Reinstall the pin. Tighten down the two
nuts that hold the points. Slacken the locking nut under the bottom points.
Rotate clockwise until they touch and back off a quarter turn. Supply power
with a set of leads. The horns will most likely sound horrible but it should
provide sound. Adjust the nut above the locking nut in very tiny increments
(counter clockwise mostly) until you bring the tone to the right level. Set
the locking nut. It is that easy. Thanks again Randall.
