Hello,
We have a computer A1466 820-00165, it does not start, the led on the charger does not light, on the motherboard there is no trace of oxidation and on the power supply it consumes 0.010ma.
We have voltage P3V42G3H (ok).
We've changed the charging circuit on the U7100 and U5000 and same thing, the computer won't start and stays stuck at 0.010ma. We noticed that the U5611 component was bent, so we replaced it and tested it directly while the motherboard was still hot, and then the MAC started up and we saw the LED light up. But when the motherboard cooled down, it no longer lit up, so we understood that when I heated this area (U5000, U5611) the motherboard was working. So we changed the U5000 again, but nothing changed.

You should post some basic voltages, at least; when the problem appears.
Exact PPBUS_G3H level (without battery)?
What about SMC_RESET_L?

Inspect J6100 for corrosion.
