Check Power at node 20 should be Battery voltage OK
Check 5V at pin 8 of SO-8 chip on the same side with MCU, node 20 is pin 1 of the same chip. ~5.6V
Check 10V at pin 1 of SO4A (small 6pin IC) ~5V
Check 10V at pin 1 of SO-8 FET drivers Are they the three next to the SO4A? If so, I get ~4.7V on each pin 1
Check all diodes, 3 pin IC's
Remove excessive heatsink compound from MCU pins

Also, when checking the FET drivers I slipped, shorted two pins, lots of smoke, and now no power :( oops
