Hello, I recently bought a used Jinlun JL50QT-5 (2005) with a few flaws. Among other things, the e-starter did not run. However, there was no battery in it. I got a suitable battery now and activated the e-starter. I recorded this and uploaded the file:http://helmut.kilu.de/Others/Instructions_Roller.MP3 I would be grateful if you could judge as far as possible what’s going on with the e-starter. The battery is “difficult” and the starter fun I’m new here and I don’t know about scooters, it’s my first scooter. Thank you very much in advance! I’m not very familiar with scooters and I’m not sure if I’m going to be able to do it again.
