Convert whatever those documents are to PDF or an image, and i can have a look,
The low side drivers should pull the coil wire to 0V when on, and the high side drivers should pull it to VCC when on, when both are off, i would expect it may float around 12V
With no power, are any mosfets short circuited, replace the motor with some resistors, (delta arrangement), pick higher values, like 10K, and measure if any of the pairs are higher or lower on idle, it may indicate one side is leaking, or one side is open circuit. similarly when driven high or low, does its voltage reflect this?
