I didn't find any ac in the test points but i did find the power supply tucked up underneath cabinet near the fans. On the advice of a friend I ordered some capacitors for the regen braking circuit in hopes that might help, as it only vibrates when the car is being pulled by the counterweight (up empty).

Id like to replace the faulty component but gaining proprietary tech support and engineering information is next to impossible. time is of the essence and i might have to replace the drive as a whole if its possible. My concern with that is there are many configurations available and this is on a 460V mod. Might not have them at home depot
Is there anyone in north america that does exchange on these drives?
