Reversed the diodes on the first soldered board and retested, which still showed a short. Realized I had some of the P and N channel MOSFETs installed in the wrong spots. Would have been good to label them on the silkscreen. I just soldered 4 other boards with the correct components and they seem to work, though I have not fully tested them all with coil loads. I did not have enough P-channel MOSFETs so I reused some old (potentially shot) ones. I have marked them to help identify them if an issue arises in the future. I updated the schematic and PCB design to reflect these revisions, rolling the part rev to 03007-001-A. It counts as a revision, not a new part number because the board has the same form, fit, & function as the sibling -001.
