    BBSHD doesn't power on

    I hooked up two 52 volt batteries in series by mistake and the connection sparked badly. I measured resistance between red and black and got 3.6 ohms. I took the controller out and measured 3.9K ohms black to green and 9.8K for blue and yellow. I applied about 8 amps across red and black and a thermal image showed the vertical cap and the heatsink by the green lead as being hot.I bought a new controller but nothing turns on. I also bought a programming cable and plugged it into the display connector. The motor still doesn't work. Help!
