Hello community, I hope you can help me here. I bought an old XJ 650, which was poorly maintained and almost always outside stand. Lief so far but and still has TÜV. Unfortunately I have the problem that the start button on the right handlebar amature has no function. If I am idle, turn ignition, then the green leper lamp is on, turn turn on and brake light. But horn and dipped light do not work. When I press the starter I hear NO click from the relay, no ts! The battery has over 12V and if I have the start relay (on the left side of the battery) with a key overbridge the box is also in front of it. Therefore the starter must be OK in itself. The oil control light does NOT glow when I press the starter. The motorcycle is like dead… The Killswitch on the handlebar has function, I measured it. Therefore it must be either the starter relay (have already ordered a new one – does not cost the world) or there is a problem in the cable The blue/white cable from the start button is mass, right? Where does this cable run along the XJ everywhere and is there still a Releais under the tank that I have to check? Unfortunately, I am almost completely blank on the topic of electronics and don’t really know how to handle a multimeter…It would be great if someone could tell me step by step what I should measure everything and how I can do it! Thank you so much? We nn is a little unclear, just ask! Greetings Lukas
