Hardware Right Joycon voltages

[Mightyjebus]

I've been working on a few right hand side Joycon's and I've been mapping voltages as I go along. I've attached a diagram below in case it's useful to other people working on the right joycon.
This isn't a comprehensive list as it's a work in progress, I know at least 5 points on the other side of the board that show 4v but I haven't sorted out a picture yet for instance.

One of my right joy-cons is dead. How can I check if the charge chip is faulty?
I changed the battery and the rail. It's still not working.

it's tricky but if you connect the joycon to the side of the switch which has a charger attached you should see an input voltage on pin 13 of the charge chip. This feeds the battery and system out pins and if you unplug the joycon from the switch you loose the input voltage but you should still see voltage on the BAT and SYS pins.

Thank you very much for the picture

I'm curious. Do you know something about the right joycon wake-up issue? I.e. the Joycon doesn't wake up from deep sleep, connected/disconnected doesn't make a difference. Pressing Sync for a few seconds and the Joycon wakes up and connects fine on the switch rail and/or via BT.

Edit: The right one also doesn't wake up if I boot the switch (from powered off) with connected joycons.

hello, very good, I know that this does not go with the topic, I would like to know on the right joycon plate what would be the point where the bluetooth synchronization button goes, what happens is that the flex of the SL/SRL and the synchronization button have already broken It's the second time it's happened to me and I don't think I'll buy that cable again, but I'm only interested in being able to synchronize both for the Nintendo Switch and on PC, but I require the synchronization button to do it, do you know where to solder?
