I have a 2DS that is not wanting to send voltage to the battery when charging. Here are some things I've noted:

• 5.4 volts is present on the back of the charging port.
• 5.4 volts is present on both sides of Fuse 1.

When I go to check Fuse 2; there is no power present on either side.
Switching to continuity mode; I do have continuity through Fuse 2 (my meter beeps steadily).

So power is not making it's way to Fuse 2.
The only thing in the middle (that I see) is the little area to the top-left of the cartridge slot.
I'm guessing this is the integrated charging controller; however, I do not know how to test this particular chip.

I am attaching a photo.
The red circles are where I am sensing 5.4 volts.
The one blue circle is measuring 3.3 volts.

Some final datapoints:

• The charge light turns solid orange when plugged into a charger.
• The power light stays a constant red while plugged into a charger.
• If I unplug the charger; the power light switches from solid red to a flashing red.
• If I use a new battery (full charge); the power light turns blue.

I'm looking for any advice on how to progress?
Which specific points to measure and their expected ranges?
How am I not getting any power to the Fuse 2 location when Fuse 1 is good?

Thanks so much and Happy Monday!

I have a Nintendo 2DS I have resurrected from the dead. The last issue I am facing is a battery charging issue. Here are some notes:

1. With a fresh battery; the system turns on and plays fine.
2. With any battery; the system will show an orange light when the charger is connected.
3. With a drained battery; the system will show an orange light when the charger is connected; but once removed.. the power light starts flashing red.

I have disassembled the console and used my meter to test for voltages.

1. I have 5.4 volts at the charger connector.
2. I have 5.4 volts on both sides of the F1 fuse.
3. Just to the left of the cartridge slot; I have 5.4 volts on one of the caps and 3.3 volts on a different cap. So I am assuming power is making it to that point.

Now.. when I go to probe fuse F2.. I do not have any power on either side. When switching to continuity on my meter; I get a good reading and the meter beeps.. so I know the fuse is not blown.

What I cannot figure out.. is "why" the fuse (F2) is not receiving any voltage in the first place. Where would I go next to trace the power line? When I flip the board over; there are no traces or components to test.. I'm guessing the traces are a few layers down in the board.

The attached image denotes (top left near charging port).. the red circles are 5.4 volts.. and the 1 blue circle is 3.3 volts.
