This sounds like a common failure mode when voltage is applied to the wrong side of your motor controllers.

Be sure that the power coming from the power distribution board goes into the terminals labelled V+ and V- on the case of your Jaguars. The motor leads should attach to the M+ and M- terminals. Unfortunately, there is no protection against applying power to the wrong side of them, and most times will not work properly again if this has occurred. The best thing to do is to trace all of your wiring to ensure it is going to the proper place.
