My iEFIS lite has been having issues on startup, losing the Hobbs time and other settings. It seems to be getting worse. I removed the back cover and the solder in battery is obviously failed. I’d rather not send it for repair and have the capability to change it.
1) Is the part number available?
2) any tricks to removing the board
3) the keep alive has been connected since it was new in 2020. Could the failed battery be pulling that voltage down?
