you know its bad when your troubleshooting in your sleep. woke up and remembered something. check your tach for loose connections and proper shielding if the voltage produced is wrong it will go into braking mode not motor drive taking your car into the overhead. that will also cause a weird pulsation that will oscillate the drive causing fuses to blow. any complaints for rougher than normal ride? check your B(braking) and M(motor) lights for proper operation.
