Horn repair question

[Jeff Balazs]

I have gone through the post's regarding horn repair but still have a problem with mine. It has been cleaned including the points and I made new paper gaskets. I still can't get it to work.

Are the points on these supposed to be in the closed position most of the time? The coil energizes but there is no buzzing of any sort.

Thanks, Jeff

I haven't had one apart, but doesn't it work by energizing the coil which pulls the points open, thus breaking the circuit which de-energized the coil allowing the points to close, which re-energized the coil... and so on. This causes the points to buzz which is amplified through the bell. At least that's the theory I'm familiar with.

Merle;

Yes that seems right.

I just got a buzz out of it..fourth time apart:o..must of been grit somewhere?

I will play around with the adjustments now that it buzzes.

Years ago I had a Model A that had been street rodded in the late 50's. It had a JC Whitney Growling Tiger horn in it. This horn sort of reminds me of that one.

If you played around with it you could get it sounding pretty amazing. At least that is what I thought at the time. Not sure the girls it growled at felt the same!

The adjustment is very, very touchy. From a 1937 horn service manual:

Loosen the lock nut and turn current adjusting screw to the left to increase the current, to the right to decrease current. Increasing the current increases the volume. Too much current will cause the horn to have a sputtering sound. This adjustment is very sensitive. Move adjusting screw 1/10 turn and lock in position each time before trying the horn. If ammeter is not available, adjust according to sound.

Note that 1/10th of a turn and re-locking the nut prior to each attempt...

Tod;

Thank you....that is really good to know. It did seem a bit fussy. Will make much smaller adjustments from here on.

Don;

That looks like a little bit later version of the one I had.

As a teenager it was great fun.

Especially when a cute gal in a miniskirt happened to be in the crosswalk.
