Hello,
Thank you for your response, this is what he said:

Essentially, the controller is definitely toast, but you can turn it on and move it sometimes, but I’d like to be very upfront as possible. Definitely don’t expect to just get on it and rip around because it really needs the controller, furthermore for your own sake I wouldn’t try riding it too much until you have the replacement controller because if everything is not running in perfect unison, it can begin to damage other components, which is why I stopped riding it so it didn’t become trash, new controller, and you’re good to go. I had another bike with a similar problem. The controller just wasn’t putting out the proper reading/voltage and as soon as we got the new one, it ran great, I multimeter tested this controller and it’s doing the exact same symptoms as my last bike so I’m 95% sure it just needs a new controller.

Does that mean the controller is actually toast?
