Hello everyone,
I have an Brainpower Motor Controller, I bought it as a new product and after 3 months of use the controller broke. I opened it up the to see inside the damage of the controller because I couldn't even do pedal. The problem was a short-circuit from one single n-channel Mosfet in the middle (blue phase). So I troubleshooted all Mosfets of the blue phase and changed all six from HY3007 to HY3208 http://en.hymexa.com/html/dn/index.html. After I opened up the controller I figured up also that one of the two green capacitors and the one small black capacitor in the pics have exploded. It was due to the vice versa polarity, so I changed them up with a new one and with the right polarity. The problem is that the controller it works only for a few meters and then throws me an error code 09 in the LCD Display S866, which is a controller failure problem. Is anything wrong with this type of Mosfet? I measured the throttle voltage and it works perfect, the LCD Display works fine, it seems to me that controller doesn't have a phase output from the Mosfet I changed and the rear wheel doesn't spin.
What should I do? To measure the yellow phase if it works properly?
