 The fuse is marked `X050F OORZ`. This appears to be a PTC with part number SMD050F ([product page](https://www.littelfuse.com/products/polyswitch-resettable-pptcs/surface-mount/smd/smd050f_2.aspx)) (0.5A hold, 1A trip). The designers are redeemed in my eyes.
 
-Based on the diode polarity, connectivity to power filter ([BNX022]()), and wire colors I think it is safe to say that CN1 pin 2 is GND and CN1 pin 1 is power.
