My m4 stopped working yesterday. I assumed it was the battery but after fully charging it, it still doesn't work.
I did a load test on the battery, That indicated that the motor wasn't engaging, so i went to take the motor out only to find that one of the motor mount screw has been rounded.
The fuse had been removed so i think something went wrong and there was no protection (probably a short circuit from the bad wiring).
Any other ideas on what could have happened?
Any ideas on how to get out a rounded allen headed screw?
