Hi together, I’m new here and introduce myself briefly. I am 39 years old trained kfz mechanic and come from Düsseldorf. My problem child is called Kymco Xciting 500i rr from 2012. First, Yes I have read all the posts and applied some ideas, unfortunately so far without success. I have the problem of breaking the tension with my scooter at the start (ctek maintenance hangs permanently) to 9 volts. I check this using the cigarette lighter (plug) as well as with Multimet battery has already been changed 2 times (once connect with 220a with 270a) no improvement. As soon as the temperature is below 15 degrees, the scooter rotates a maximum of 1 revolution until it arrives at 9volt. Even when bridging and also with a booster (70a) the voltage falls off. The problem usually exists only in the morning. As soon as the temperature rises over 20 degrees it immediately starts without starting aid. Voltage then at 13.4v. controller came new last year. Since I the Probl I’ve been using a lot of things from the forum for a while. Starter is new (was a carbon-broken oil change from 10w to 5w (in terms of viscous fluid) spark plug heat value changed (to try and rebuild) Additional mass cable from block to frame. Since I’m already selling the scooter at that point I’m asking for more solutions here. Someone else a tip ?
