Primary glide slope not working

[dzeleski]

Hi all,

I ran into a problem upgrading my 430 to a 440, but this issue also exists on the 430 so its not upgrade specific. When I bought the plane the glide slope worked just fine, 30 hours of flying later and the flags are up but the localizer works. Yesterday I went to pull my KI-214 to get it serviced and noticed a diplexer directly behind it, then I noticed an antenna cable not connected to anything, following that back to the diplexer G/S 1 port. So I put the the two together and reached behind the now installed 440 to find that the G/S antenna is not plugged into the back of the unit. Makes sense why the flags are up...

My question is if I plug this guy back in is there any chance that I blow something up? I cannot find another loose connector and the cable 100% goes to the diplexer G/S 1 port and the glide slope did work 20ish hours ago so I assume it didnt get fully locked and vibrated off. Thoughts?

 

Edit: Self test works just fine on the indicator (up and left, flags off, and both GPS and VLOC on).

No, you won't hurt anything. Go ahead and plug the antenna back in and see if it works.

Cool thanks, Ill plug it in and give it a flight test. Hopefully an easy fix
