I got caught in pouring rain the other day and I covered my throttle for my E-Bike with a plastic bag, but that didn't seem to help. I switched out the throttle with one I've never used.. I get the same really rough/grinding sounding sound coming from the motor.. It only does this when it gets caught in heavy rain storm.. I let it dry out for a few days and it just works normally on it's own. I can't figure out what the problem is.. I have everything sealed up the best I can, yet it seems water got in somewhere..

It's been a couple days since I got caught in the rain and it's still acting up. Sometimes the motor will turn and other times it won't... I know it's not the throttle, as I have a new one I switched out. It's not the battery, as I tested it with another with same result. It's either the controller or the motor. Maybe something isn't right with the motor, and controller is preventing it from turning ? Sometimes I can get it to turn if I unplug the motor cable and battery, and then plug it back in again. When it does turn it makes this loud grinding sound. I made a audio recording of when it was running last night.

Here is the file, and I'm applying full throttle the entire time: https://www.dropbox.com/s/9nkdt4xjv3...20011.m4a?dl=0
