Hello everybody new to this website. So I’ve owned this 4 tech full suspension mountain bike a mongoose 4 tech. I put the BBS02 750 W mid drive kit on it from essential bikes. Didn’t have much luck with diagnosing my 30 H code that popped up on my display. The code popped up after I cleaned up the install disconnected and reconnected the plugs. I’ve rebuilt outboard motors and I’ve dealt with wire harnesses before and felt that I was pretty careful and put in the Plugs back just the way they are supposed to go. So the symptoms are: the throttle now works even if there’s zero PSA on the display The display has no control over the performance it does not show speed but yet the speed sensor indicates it’s working with a red light ,it does not indicate when you break on the screen but yet the brakes work in the motor in a interrupts as well as the shifter interrupts when shifting. Any help would be greatly appreciate it. Examining very closely I can find nothing physical that should be causing this problem. Pre-clean up I’ve actually road bike almost 90 Miles flawlessly and have really enjoyed it. Thank you
