If "motor wires fired" means the wiring from controller to motor caught on fire, it usually means the phase and/or hall signals shorted together, which typically blows up halls in the motor and FETs in the controller. Often when FETs are blown the gate drivers also get damaged.
Sometimes damages other parts of the controller, or even the other 5v-powered devices on the system depending on exactly what shorts in the cable and the sequence of failures.

The motor works with no load, wheel off the ground after rewire. Once under load it makes crunchy noise.
