Cheers for the clue, I am really new in motorbike electricity. Could you tell me more specifically which wire loops should I check. I would be really pleased. Anyway, I will double check all the connectors and have a look on the cables. But there is so many that I just didnt know where to start and how to check it with multimeter.

Edit : I checking cables, but I still cant find anything helpfull in workshop could anyone help where I should look for wiring testing procedure
