Dear Listers, The Matronics Email List Server was having some issues and not accepting incoming posts for a couple of days. It is resolved now. Sorry for the hassle...

During normal cruise (following start and battery recharge after start), the bus voltage varies from ~13.7 to ~14.0V. The current flow to/from the battery varies both in and out up to a max of 9 amps out all the while battery voltage remains steady at ~13.9V. During these times of battery discharge, load was static (which is to say the load was not deliberately changed). Any insight as to what is going on is appreciated. I have a spreadsheet with the data from this flight that was generated from my my EFIS, but which I was unable to upload as an attachment to this email.

With the help of Garmin express, we can find the location of the Garmin devices. And for the computer connection, we can use the USB cable. Garmin Express is the best product for GPS and used to manage and update Garmin devices but sometimes because for many reasons, Garmin express does not work or Garmin express not finding devices (https://www.customerserviceshelpnumber.com/garmin-express-updates). In this case, we need to fix Garmin because it may be Garmin updates problems or any other. So if you are one of them who is getting technical issues with Garmin, then without any hesitation contact Garmin express support (https://www.customerserviceshelpnumber.com/garmin-express-updates) team to fix problems or visit the website for more information.
