Hi All
Just wanted to post an issue I have been having for some time and see if anybody can give me some tips.
I Have an MGL EFIS system and for a long time now on the ground only my GPS will drop out and come back alive on repeat.
I then started playing around with the idea that interference from some device is causing the drop outs and very long story short I have managed to pin down the issue to my alternator. **only during idle RPM**
After my aircraft idles for about 5min @ (800rpm) I will consistently get these "GPS not available...... GPS available" notifications. If I switch off the alternator the problem goes away instantly.
I have got a capacitor wired in the alternator system already, just wondering what other modifications I can make to try and remove the interruptions/interference.
I have a backup battery to the efis running as well so voltage drop is not the issue.
Thoughts?
Thanks in advance
AJ
