Default Cooling the shop.

I found a few wiring diagrams here;

From the quick glance, it sure looks like if you disconnect the AC, that
there is motor windings across the cap.

Do you have a wiring diagram online I can see? I could easily be mistaken.

When you turn off the power to the device, the electric fields in the

all collapse. And, the cap is left hooked to a short (through the motor
windings). So, regardless of when you shut off the power, the moment the
power goes off, the cap discharges through the wires.

A run-capacitor motor has the cap in series with the winding. When
power is shut off, there is no path to discharge the cap. Only if the
cap were in parallel with the winding, would it be discharged as you
say. But then it wouldn't phase-shift the winding current.
