Piezo Alarm Question

Umma Gumma

Recommended Posts

I have a 2004 115 Optimax. The piezo alarm under the dash is shot (no beep when turning key to "on"), so I went to radio shack today and picked up another. When I hooked it up and turned the engine to "on", I get a loud, noticeable beep. Problem is after the first short, loud beep, I get what sounds like continuous feedback at a much lower volume. There's a distinct difference between the "beep" and the noise afterwards. I checked voltage at the piezo plugs, and it's 12v anytime the key is on.

Do I have a short somewhere, or is the aftermarket piezo not the correct one? It indicates it works between 5v and 28v or so.

Thanks for any thoughts on the issue.

What is the history? Have you owned it for sometime and it had just quit working?

I guess my first thought it that something in the warning system is sending the signal, whether its one sensors or the warning module is 10-7. Im not completely familiar with the Opti's system but constant voltage doesn't sound normal.
