I started hearing an interment clicking sound in my headset about six flights ago. The clicking has NOT happened on every flight. On the last flight the clicking was very prominent and the tower said my transmissions were garbled. I assume the clicking and the garbled transmission are related but I am not positive. This is the only instance of a garbled transmission.
-A couple of the steam gauges twitch with in concert with the clicking.
-If I turn the radio off, I cannot hear the clicking through the intercom but the stream gauges still twitch.
-The clicking is NOT in sync with fuel pump strobes or anything else although the fuel pump may exaggerate it some.
-The clicking occurs with all equipment off except radio, intercom and the one Lightspeed EI (I just thought to turn off the EI and see if that tells me anything)
-I can reproduce the clicking during taxi but the engine must be running to reproduce.
-I also now hear a click when I turn on various equipment via a toggle switch .
The plane has a single point ground forest of tabs, Bob Knuckes three buss architecture. Data, antennae wires are run separately from power.
Under the panel I have tugged on wires/connections with the headsets on but no luck fining any loose connections. I am looking for suggestions on how to isolate the problem, trouble shoot the problem, or just theories. My plane did not have this issue for 125 hours, something must have changed but I don?t know what. Thanks.
