Macbook A2242 Amp Meter Rebooting

[Instafixx]

Hello,
I have a 14 inch Macbook Pro A2242. When put to charge via USB C i can see a very dim apple logo and it stays on for sometime and goes away and comes back on. I hear the chime too sometimes.

When checking with an Amp Meter it goes upto 20V and then the amp meter restarts after some seconds.

This is happening in the all 3 ports. (With Battery Disconnected).

PPBUS_AON is at 12.3V and cycling too because of the amp meter i guess.

Please help ho to proceed.

[Update] With the battery connected the Amp Meter does not reboot and draws a steady 2.5Amps.
Mouse Click is there. No Caps Key Light. No Chime. No Boot

Do you still get dimmed apple logo?
Test for external video.

Now the dim apple logo comes for about 2 seconds when i press the power button and goes away.
Nothing on the external display.

Try DFU; revive, if still think to save some data.
Go for restore, if no data needed...

Try again DFU restore with empty SoC ROM.
Don't forget to make a backup first.

What is Empty SoC ROM. I have no clue about this. Can you guide me please ?

Being M1 platform, is marked as SPI NOR (U2010); sorry for confusion.
Read it and make backup, then erase it and try DFU.
