Chelton Sport Teardown

This video shows how the Chelton Sport EFIS comes apart. This system is an over 20 year old design, and is no longer manufacturer supported. This means that if you are one of the lucky (unlucky?) owners of such a system, you absolutely NEED to become self-sufficient and self-supporting. Hopefully this video gives some good enough background that you can open your screen yourself and fix your own issues. In the video I mention formatting a card using a mac. The way to do this is insert the card reader and find out what disk number it is using the disk utility. Then open terminal and to format the disk, type a command similar to this: (This assumes it's disk 4)
diskutil partitiondisk /dev/disk4 1 MBR "MS-DOS FAT16" "CHELTM" 0B
Windows 10 does a horrible job making a compatible format at times.
Good luck with your self-repairs of any issues you have.
