Tried. Same thing. I noticed high consumption of current on L7510 and L7520(around 4.5 amps) when injecting 1V on those coils. If I remove Q7520 and Q7510 it draws only 0.75 amps on bench PSU. Tried replacing both mosfets, still same abnormal consumption. I think there may be a short to GND before mosfets.
