Hardware New 3DS XL doesn't want to run from the battery

[T0biasCZe]

I did some repairing on the 3ds, but it doesn't want to run from the battery now
When I put it in the charger, and plug in the battery, it starts charging it, and I can turn it off, but when I disconnect the power cord, the 3DS turns off...
The battery is not the problem because it does this even with different battery from working New 3DS

Sounds like it's a demo unit 3DS console that requires it to be plugged into a power cable at all times. There doesn't seem to be any solution to this last time I heard about it so you'll probably have to keep an eye out for a replacement working motherboard from a cracked screen 3DS unit.

Its normal new 3ds xl, not demo one. and it worked from the battery before

When re-assembling, are you sure everything was re-connected properly? Skimming the ifixit teardown, it appears the battery is connected to the button pad, so if that ribbon cable in not installed properly maybe that is the issue?

Admittedly, this is unlikely to be the cause because just pulling the battery out of my 3ds while charging it shuts it down, but if you are certain the battery is good (and charged) and the 3ds was working properly before your repairs, the only issues I can think of would be disassembly/reassembly related

Yeah if the battery isn't connected it wouldn't turn on in the first place
And the ribbon cable that connects the button pad and motherboard can be connected in only 2 ways, and it works it neither of them

I took multimeter and found out that there isnt countinuity on this part. Could it be blown fuse?

Looks like so, that is fuse #2

Do you know what is the value of the fuse? I couldn't find what amperage it is...

It’s 1.5Amps i believe. my old 3ds xl had the same problem and it doesn’t have continuity on the f2 fuse
