Curricious problem: battery is not charged

Servus people, maybe one of you can help me! My KLR650 got TÜV 4 days ago and is already standing still. After I could flex for about a quarter of an hour without any problems, it went out during the ride. Keys turned around again but indicator lamp Neutral does not glow. E starter does not work either. Pushing is relatively easy, then it also works well. However, from there on the light did not go right. Quite dark and flickering. If you slow down, the Light brighter, also when blinking. Also very funny: temperature indicator and rev indicator only go when the light is switched on during the ride. When the light is switched off nothing is displayed. New battery (full) installed and new indicator rear with load independent relay. While doing so maybe something wrong connected ? E starter and light also a few days later does not work. Push no problem. Someone an idea ? Gracias!
