jay507 Posted March 1, 2021 Report Share Posted March 1, 2021 After being Corona-grounded, my EMS D-120 does not work properly anymore, running the initial screen again and again. So I am looking for a functioning one, used or new or refurbished. Thanks, Jay HP-1708L Quote Link to comment Share on other sites More sharing options...
Bill3558 Posted March 2, 2021 Report Share Posted March 2, 2021 Mine is on the way to dynon for bench testing. Low current alarms and failure to boot. Their policy is they will check it for free, if they find a problem it’s a flat $450 to repair. Not a bad deal . Good luck with your search, but repair may be another option.

Bill3558 Posted March 2, 2021 Report Share Posted March 2, 2021 Have you tried pulling the 37 pin connector and applying contact cleaner? That may be all it is. Quote Link to comment Share on other sites More sharing options...
GlennM Posted March 2, 2021 Report Share Posted March 2, 2021 Was it just the alarm or because it was not reading current? If just the alarm, did you try turning off the current alarm in the setup panel? If it is not reading current, leading to the alarm, did you check the connections at the shunt?

CTSW Bob Posted March 2, 2021 Report Share Posted March 2, 2021 Where did your amps go? Quote Link to comment Share on other sites More sharing options...
Bill3558 Posted March 3, 2021 Report Share Posted March 3, 2021 The flight started out normal, 20 minutes in it started bouncing around - 30 and more. It even touched negative 99 at one point. I know it’s erroneous because the battery continued to charge. I would silence the alarm and the amps would bounce back into the yellow for a moment and then go red again which retriggered the alarm. It’s an audio alarm over the headset. I had to turn the EMS off. Landed at an airport, cleaned the fuse holders at the shunt. Took off and it was fine all the way home. next day it failed again. Very frustrating. Quote Link to comment Share on other sites More sharing options...
CTSW Bob Posted March 6, 2021 Report Share Posted March 6, 2021 If you do send in for repair, send both displays as Dynon will upgrade the software on both for free. If you don’t have the latest software n both displays they will not communicate with each other. Quote Link to comment Share on other sites More sharing options...
Tom Baker Posted March 6, 2021 Report Share Posted March 6, 2021 Or you can update it your self, not a big deal. I've done several over the years. Quote Link to comment Share on other sites More sharing options...
