Everything is fine, except that the wing tip strobes can be heard like a

Sounds like a problem I have had with a Whelen power pack.

Can you hear the sound at the power pack? I could.

When I called Whelen, I was told that the problem was a bad capacitor.
They told me which capacitor to replace. I replaced it and it worked fine
for a few years, although the noise is just now starting to come back.

The power pack, however, is riveted closed. So I had to drill out the
rivets, replace the electrolytic capacitor, and put the box back together.
Took about 10 minutes on the phone with Whelen tech support; 30 minutes of
labor and a $2.30 capacitor. Needed some pop rivets, too, to put the box
back together.
