Scott,

Your name says it all, you could be even cheaper than me! : )

Yes, fixing a horn is relatively easy. All it has inside is an electo-magnet which pulls on a diaphragm. The diaphragm has a conyact point on it which opens the circuit to the coil and allows the diaphragm to return and close the contact....

Before you dis-assemble the horn, connect it to a battery of the correct voltage, 6 or 12, and see if excersizing it helps, sometimes this will clean the points and restore the horn to it's original "AFLAC Duck" glory.

Also, examine the outside of the horn carefully, look for a screw with a lock nut or thread locker on it. If you find one, this is an adjustment for the contact point gap. You can often restore the horn by adjusting this screw.

If you have to dis-assemble it, figure out how the point gap is adjusted, then clean the points and re-assemble it with screws and nuts for testing. You may have to do this a couple of times to get an acceptable tone. Then you can pop rivet it if you want.

Keep in mind that a horn draws a lot of current with the points closed so don't leave it connected too long if it is not honking correctly.

Go for it,

Ron
