Topic: Operational Lamp Warning Buzzer ?

[fizzsnob]

Does anyone have a lamp warning buzzer (C6AZ-14931-A) that still works?

I have gone through three, never installed NOS buzzers, and none of the work. I pulled apart one of the metal cans, and it's not entirely clear to me at the moment why it's not working... That will be a task for this weekend.

Does anyone have one that actually works? Does anyone have the schematics for the thing before I spend the time to figure it out?

 Thanks !

What year Mustang? Are you aware of the Mustang Assembly Manuals? There is an electrical manual for every year from 1964 thru 72.

So,  this is a Ford accessory that should work with almost every year Mustang after 65.

The point is that all the ones I have found that still exist do not work.  There must be something about them that has aged out and prevents them from working.


I have torn one apart, and it's a clear example of early 60s engineering. Its primitive. If no one else has figured this out yet, I'm going to go figure out why it no longer works.

A pic of the guts would be useful. And how many pins does it have?

Here is one I found online:

It might also work a bit like your car's horn. Switched (+) to an electromagnet that pulls a small diaphragm in. Out when the electromagnet has pulled in all the way which then contacts a set of points that breaks the connection. Back and forth it goes making a buzzing sound.

Here is what the inside looks like...

Take a look at the contacts and see if they are "fused". Try and separate them "gently". And some continuity checks would also be helpful. Otherwise - round file.

I would use a flat file on the points. Haha

^^ This will tell you if it's the buzzer or something in your car's wiring!

Mine (a '70 Cougar) had a compound issue: the buzzer had an open in the coil right where it is soldered to the main wire.  I was able to solder it back together and get good continuity.  However, I also found that the PO had cut the wire for the key buzzer at the turn signal switch connector.  Luckily I was able to re-pin that wire and insert it into the connector again.  Buzzer restored to ...intermittent functionality >.< 
My remaining issue turned out to be a gunked up door jamb switch.  So it would work in warm weather but not in cold weather ~ even though the courtesy lights all worked fine all the time.

Anyhow, I hope that helps, and I hope you are able to get your buzzer working again!
