No. I pulled the fuse before installing it, and put the fuse back when I was done. My lights flash and everything and the buzzer does not go off. I have tried it with another buzzer and it did indeed work. But the sound of the other buzzer was a siren and not the sound I was looking for. I tried hooking the Piezo 273-073 Buzzer to a 12 V Battery and nothing happened, so I am starting to think I got a Dead Buzzer, but Radio Shack is out of stock since I got the last one.
