PP/CP Diode Check Failed

Just in case anyone else comes upon this problem..

When I tried to use my openevse I built from kit I was getting the message

Diode Check Failed.

It turned out the pre-wired CCS handle and tail I'd bought from China (to avoid the shipping from Europe) had the CP/PP pins swapped.

The plug was labelled correctly just the pins swapped.

Interestingly the phase labels are transposed but are pinned correctly.
