My Zodiac has a GNS430W and a Garmin GI106 indicator, connected via the Approach Pro-G wiring system. Recently, the glideslope needle hs gotten intermittent: it stays dead center, even right as the 430 is powered up and on the self-test. I can enter maintenance mode and show the problem.
Three times now, I've gone in and disconnected the plug from the back of the GI106 to try to troubleshoot the problem. Each time, it's started working just as soon as I've plugged it back in. The DB-25 in the cable was originally not fully mated with the one on the indicator when the slide lock was locked; the second time, I put in a couple of little washers to make it mate more fully, and thought that had fixed the problem. It didn't.
Yesterday, I went to the airport, meter in hand, to measure the voltage at the GI106's connector, just to see if I could see the problem. You guessed it: there was voltage at the appropriate pins of the connector when I measured, and plugging it back in showed it working again.
This is about to drive me nuts. How am I supposed to show folks what a GPS LPV approach looks like at Gaston's if the glideslope needle doesn't work?
Any suggestions? I'd like to isolate the problem before I take it to my local Garmin dealer for a warranty repair...
