Default My fix for RV-12 intercom problem

For the past two months I have fought audio/intercomm problem on copilots side. By chance I grounded the headset speaker jacks to the airframe contrary to 31B-17 steps 3 & 5. My radio and intercom now work. To test this theory place an alligator clip with a wire to ground and clip it to the Headset speaker jack (largest diameter pin hole) on the seat floor. I hope this helps. Gus at Vans tech support said it should not help, but it did for me. Good luck.

This indicates that the wire which should be attached to that jack terminal and running back to the audio ground is not hooked up, or broken.

The "CAUTION" was loud enough to hear, much louder that when the Skyview audio output test was being run.

I'll run a few more experiments next trip to the hangar.
Hi Rob,

Were you able to sort this problem out? When we engage the autopilot it works well as an autopilot however the lady keeps saying caution non stop.
There is no message on the screen to indicate what the problem is.

My wife and Jetguy (John Albury) messed with multiple settings, for which I'm not quite sure what did the trick. She can't recall all the tricks, but included futzing with the volume control on our headsets while adjusting output volume and squelch on the comm radio--my guess is that since we couldn't seem to get much volume out of the the skyview, by reducing the Comm volume and increasing the intercom and headset volume, things got generally balanced. If Jetguy can recall the details of the magic, I'm sure he'll respond.

I met Jetguy while he was giving transition training to my RV-12 buddies at KGKY. He is the pro on all things Dynon. He was hearing precautionary warnings in his plane (IIRC), that many folks had yet to hear- based on settings, etc. Based upon my conversation with him, if he can't figure it out, it probably doesn't exist! He's the wealth of local knowledge on these settings. Highly recommended for his RV-12 specific Dynon expertise!

If the fiberglass on the sides, has been trimmed per the plans, all screws can be removed from the fwd top skin without removing the canopy (I have done it many times).
Can it be trimmed years later? How so?
