ES-Audio Warn

[Ron B.]

I have an ES-Audio Warn circuit installed in my RV-14A and have it connected to my SV- INTERCOM-2S. When I lift up the stall warning tab on my wing I hear nothing. On advise when installing I added a 600 ohm resistor before making the connection to pin 17. I'm wandering what I could do to test the ES- Audio Warn circuit directly so I can rule out it being faulty?
Thanks Ron

You could wire an audio phone jack directly to the es warn ouput and connect a headset phone plug directly to it without the intercom as a test.

Thanks, I omitted the stall switch and ran a new test wire from the sense position to ground. Man it's loud. Hopefully I can tone it down some when I figure out what's wrong. With my short memory I do not recall why there are two resistors on the sense line coming from the switch. I plan on removing one and trying that.
Thanks again for the suggestion.
