Strange charging behavior with no amber led

I bought a MBA 11" as not tested, and it does not charge, or show any led on the charger. How ever, when i disconnected the interconnect cable to the I/O board and connected the charger, the charger lit up green. After i reconnecter the interconnect cable and plugged the charger back in, the green led lit up and faded shortly after. I checked the charger with my MBP 2015 13" and it works flawlessly. what could cause this behavior?

Are you using a MagSafe 1 to MagSafe 2 adapter?

Like this one? https://store.storeimages.cdn-apple.com/...

The MagSafe to MagSafe 2 Converter allows you to use the MagSafe connector on your LED Cinema Display, Thunderbolt Display, or MagSafe Power Adapter to charge your MagSafe 2-equipped Mac computer.

It sounds like either the cable or the board it’s self has a problem. Inspect both looking for damage, the cable or board might have damage within the connectors or there might be liquid damage. Here’s the guides for both and they both offer parts info as well
