All right, I did some Google searching (sorry - I should have started there)
and now suspect that my problem is in the grounding. But where in the
system? Can I fix this, or is it back to the avionics shop?

Thanks,

Michael

When I turn on the alternator in my '79 TR-182 I hear a faint highpitched
squeal through the headsets. No squeal when I just run on battery. Is
there
a simple way to fix this?

TIA,

Michael
