Do:
- Shut the Pi down from Mainsail; wait for the ACT LED to stop.
- Rocker off; unplug wall, then inlet; cord out of the room.
- On its side, open the bottom panel; meter DC V, +V to −V.
Check
Rocker unlit, PSU LED dark, no cord at the inlet. The meter reads 0 V and holds it for ten seconds.
What you're looking at
The fan lead lands on the Leviathan, under the deck and beside the PSU's mains terminals. The bay opens only on a dead machine, exactly as at 11.67.
Caution
Who is in the room, 00a.2: one adult at the machine until this Check passes. The helper stays out of the room until the meter holds 0 V and the cord is gone.
