Skyview & Garmin 430W nav problem.

I've been flying for a few years with the 430W & Skyview combo. Recently I'm getting a problem with selecting a VOR on the 430. I can't get any indication on the skyview's HSI. GPS works perfectly and strangely if I select an ILS approach I get all indications perfectly. With a VOR it's like the VOR is dead. So thinking it was I've been trying a few. I also have a Val Nav 2000 and that receives the VORs fine. Does the 430 put out the signals to the Skyview on the same channels for VORs and ILS? I think so. I have the Arinc 429 installed, but I know I ran some serial wires between the 430 and skyview.

Are you receiving the Morse identifier on the 430W for the VOR?

You might try swapping your NAV and GS inputs on the 430 and see if the problem moves.

There are two wires specifically for the VOR/ILS data from the 430W to the 429 ARINC. Channel A goes from pin 24 of the 4006 connector on the 430 to pin 22 on the ARINC, and channel B goes from pin 23 of the 4006 connector on the 430 to pin 10 on the ARINC. I know that the ILS data goes on channel B, I had a broken wire on that pin a while back that stopped my ILS function from displaying - but I don't know if the VOR data is on the same channel, or on channel A.

The GPS data (both directions) is carried on a separate set of connections and will display just fine regardless of the condition of the VOR/ILS side.

Good idea, Airguy. I'll see if I'm getting the identifier. I did try swapping the antennas. I switched between the second NAV and the Garmin. Same exact thing so I don't think it's antenna related. Thanks guys, I'm going to do more detective work this week.
