Lenovo Legion 5 Pro 16ACH6H Type 82JQ – Shorted EC Chip

PL6201 = 3.34v, PL6202 = 5.16v.

Close the jumpers PJ6205, PJ6207 and measure the resistances on all pins of the KBC chip in reference to the coil PL6202.
It's not necessary to specify all the measurements, only specify the resistances that are less than 2kΩ, if any.

All of the ground pins (1, 27, 49, 75, 91 & 104) have a resistance of 1.14kΩ. Everything else is over 2kΩ.

But you previously measured a resistance of about 5kΩ on this coil in reference to ground:

PL6202 = 5.44kΩ

PL6202 = 5.4kΩ

Yes, measuring PL6202 resistance to ground, I'm getting around 5.4kΩ. I also have the same resistance to ground from PJ6207, but from any ground pin on the KBC with reference to either PL6202 or PJ6207, I have 1.14kΩ. I have rechecked twice, but the results are the same.

Check this resistance again with the revered polarity of the test leads.

Ah yes, of course, I see my error
I should be using the Black probe on the KBC ground pins, so I'm measuring resistance of the coil to ground, just as before. It is now 5.4kΩ
