I used my Dragonfly for the third time last weekend.
The wiring harness connected correctly, but the locking "butterfly" did not lock the harness in place, and in fact, the wiring cable fell out of the back of the sounder.
I tried to remove the "butterfly" to reconnect the harness, but it was very difficult to turn and remove.
The upshot was, when I got it all reconnected, the sounder would not even have power running to it.
I found later that the large plastic locking screw (at the rear of the sounder) had revolved, and although I haven't touched the thing in case my warranty is voided, I think that the wires inside the sounder have come adrift. (I can hear something rattling around inside the sounder).
I don't know why the locking nut has turned, but it seems either shoddy workmanship, or a design fault.
Just wondering if anybody has found a similar problem. I am hoping this will be covered by warranty.
Thanks for any responses/input.
