No wires should go directly from the power distribution board to the motors. Wires go from the PD board to the Jaguars' input and other wires go from the Jaguars' output to the motors.

If you reversed connected the input power to the Jaguars, they are most likely destroyed. When a power FET is destroyed, it will usually become a short circuit.
