Would the electrical interference pose any threat to the avionics? Or would
the interference just be annoying?

The interference can manifest itself as a popping sound (rate follows
engine rpm) that is heard only when the squelch in the COM receiver
opens (loudness follows COM volume control). If the interference is
not strong enough to open the squelch by itself, then you will not
hear it until a real radio signal opens it, at which point you will
hear the signal contaminated by the popping. If the signal is weak
(distant), the popping can be so bad as to make the signal
unintellegable. If the real signal is stong (you are close to the
source), the interference is less noticable. If the interference alone
is strong enough to open the squelch in the COM receiver (with no
other signal being received), then you will hear the popping sound
continuously, even while the receiver would normally be silent, in
which case it gets VERY annoying.

The interference does not threaten your avionics; only your sanity...
