I had this same issue last year. Everyone here was so helpful. I just could not find the source of this power loss. I even sent both servos back to Dynon, where they were run for a few days, and returned to me in normal working condition. The HDX menus did not find either servo (like they were...

Morning. The answer is simple... unknown. Since this episode began, my HDX has made no mention of any warnings. It IS working, as I do get other warnings (oil pressure, etc). It could be because of settings done by the previous owner? I have been a 6 pack flyer for 40+ yrs, and this machine is...

What an adventure. Finally got it fixed. (and BTW, Don at Dynon, et al, were VERY helpful and walked me thru things). Suggested I try alligator clip direct from battery to servos, and they both worked. But when hooking things back up, nothing. Then alligator'd from battery to both servo power...

This is based on memory, as I ran config again today, after removing both servo grounds and the AP disconnect, putting on new ring terminals, and attaching them to different ground connections.... but no change. I (continue to) have only 9 devices found... all Dynon units.. ADHARS, etc. My #1...

I will check that again. But, let me ask one more question.... and I dont know why it didnt click on me earlier. The top bar across both of my HDX screens contains no info other than the UTC clock. No frequencies, no txpdr... nothing. Just the clock. ???

I should have been more clear. This was the back of the AP control panel (SV-AP-PANEL/H). Looking at the above (if the control panel functions the same), then a fast flash means the module is operating normally? I've been checking all connections, and still find no AP at all. Servos still not...

I just noticed this, checking all connections on back of the AP head. When the DB9 is removed, it flashes red slowly. When I reinstall the DB9, the LED flashes red rapidly. The AP head is lit… so there’s likely power to it. But what does the red slow/ quick flash mean.

Mike, MANY thanks for the offer. Sadly, I am in the cornfields of Nebraska... a little ways from NH! And out here, few techs/shops will work on experimentals, even tho much is standard in my Glastar. More to come. Isaac.

Mike, MANY thanks (and airguy and jnmeade). These suggestions are SO helpful. Yes, I had many contacts with Dynon techs, and they are always receptive and provide outstanding customer care. I had both of my units sent back to them, and they functioned ok. I just reinstalled them 2 days ago, and...

Thanks, gents. Checking C/B's. DB9's looked good.

Wondering if anyone has experienced this. My A/P on the HDX has disappeared. We previously replaced the dual electronic ignition system, and the plane was AOG for some months. After getting back in the air, I noticed no A/P settings at all.. not even on the menus. It appears the HDX is not...

HEB... thanks... thats exactly what I was doing wrong. Appreciate the help.

I am tying to dump recent engine data onto a flash drive to send to Savvy, for some engine analysis. But this time, the csv files Savvy needs (user_log_data) wont let me open any of them, as they are password protected. I dont use Excel, and therefore, dont have any passwords. I tried to just...

Excellent. I was on the correct path. Thanks.

I am installing a FlyEFII System 32 in my Glastar. I completely removed the old EFII legacy system, as this newer system is much more 'plug and play'. Yet I am unsure where to route the tach line to on my Skyview. It says to attach to the RPM input ... where is this located? (And I assume...

Its not the first use. The previous owner reported the same thing, and said he had a sequence of fixes to perform on the ground, but did not make those available to me. Would you kindly show/tell me where this specific guideline is located? I might be able to follow it on my own. Thanks!

Hello all. Just got into a Glasair Glastar that was fortunate to have dual HDX's/AP installed. Two issues I have... first is that hdg and track just wander back and forth 20-30 degrees... like a gentle roller coaster. It can put you to sleep! I've restarted the system each time, but to no...
