Question on GTN 650 with A2A Cherokee 180

[Bobsk8 12,717]

I discovered that when I fly the GTN 650 with the A2A Cessna 172, I can fly a normal ILS with LOC and GS using the upper OBI indicator on the panel. When I try and do this with the A2A 180 Cherokee, and I set the LOC frequency in the GTN, the freq in the lower Nav 2  radio changes to the LOC frequency, and that lower OBI indicator only has one needle that tracks the LOC, but no glideslope indicator. The only time the upper OBI indicates is when the GTN 650 is switched to the GPS mode, then the upper OBI indicator comes alive. My question is to anyone that has  both the A2A Cherokee and the GTN 650-750, is this normal for that particular aircraft?

Disregard, I found the problem. I had a blown fuse in the A2A Cherokee for Nav 1 radio, which also powers the upper OBI... :smile:

yes, and I should know better since I spent my entire career teaching electronic troubleshooting.
