Can't change modes and won't turn off manually

I have an evolve bamboo GT with 107 Wheels and 200 KV race Star Motors A couple weeks ago I picked up a rock on the way to work it bent the motor mount and the motor shaft. So I was riding on one motor until I got a new motor mount and motor. Didn't think it was a big deal running on one motor but about 4 days after that the motor got so hot at the solder on the motor control melted needlessto say was not good. I replace the motor control and the two Motors put everything back together. Now I can't turn it on from the switch and and I can't change modes. What else should I look at .
