A Macbook Air M1 A2337 has arrived with no fault declared on the job. Using the PLD-USBC Meter it's found that there's a 450mA periodic glitch and no 20V being setup, which typically indicates there's a fault around the PMIC area for these machines.

This fault ended up being slightly trickier because of the way that schematics & networks can sometimes be separated yet the same thing electrically.
