K3 unusual noise

[Scott McDowell-3]

Hello
My factory built K3 is about six weeks old and today it started doing something that I have never
had a rig do before in 40 years of hamming.
 
I was listening on 20 meters CW and the K3 suddenly started making a fast ticking noise at various
speeds. The wind was blowing about 40 miles an hour and I suspected that. So I disconnected the
antenna. The ticking noise continued. So then I turned the K3 off, and even with the rig turned  off
and the antenna disconnected, the ticking coninued for several minutes. The ticking was about as
 loud as one normally has the audio set when in use.
 
Since the rig was new I have had a one megohm resister across from the center conductor of the
coaxial cable to the braid on the coxial cable.
After letting the rig set turned off for a few minutes, I turn it back on and everything seems normal.
Anyone have any ideas about what might be going on?

Scott...

Lift the top panel and check the cables that run from the left side
across the fans in back near the finals. Betcha one is just nicking the
fan and making your "ticking" noise.
