Chosen Solution
While replacing the left thumbstick, I disconnected the battery cable from the connector (circled in photo). Unfortunately, I broke one of the contacts on the connector. I’ve searched for the connector, thinking I could desolder the broken one and replace it, but I can’t find a match. An alternative, I suppose, is to hard-wire in place of the connector, but I’m not wild about that option. Any suggestions?
Contact TronicsFix on youtube, charming guy with a lot of Switch parts. I’m pretty sure he could sell you a battery connector or even replace your broken connector.
there’s a few solutions, buy a broken motherboard and salvage the connectorsolder it directly, pretty jank but it should work. be careful when soldering it and check for shorts afterwards.
I found the piece on aliexpress if you cannot find a motherboard for it. i had the exact same problem sadly. As i was repairing the joystick too. https://m.aliexpress.com/item/4001264431…
Did this ever get fixed?!? I just did this. I have a 250+hour island on animal crossing, I cannot lose it!
