Club Car ds big electrical issues.

[Crawler487]

I have a club car ds 48 volt with the IQ system(the cart is completely stock and the governor kicks in around 17 mph) Well my friend and I were driving it and we hit a bump and the golf cart accelerated very quickly to way over when the governor kicks in usually, so I let off the throttle and then the carts regen feature turned on and stopped the cart, as if I flipped it into neutral at full speed. When we lifted the seat it smelt like burnt electronics and when he tried to see if it still worked it wouldn't move but the reverse buzzer came on. I'm wondering where I should start, and how?
