Hello, it's my first time posting here since i'm new to riding etc. So i just bougt a 2014 exc wich had the top end rebuild not lang ago, great buy good price. Only thing is it came with the bendix out, so i watched some videos and installed is myself, its in good and everything fits, so now i press the e button and hope for the best but nothing. So i connect my battery to a charger and its dead, well okay no problem i go to a friend and try a battery from him, now i have that battery in and when i crank it it just makes the noise of the motor turning over but it doesn't hook, and after 5 sec it runs the battery flat. What could be the issue, if you need more information i'll be happy to deliver.
