Hello together, I have the following problem and indeed after my handlebar conversion the left turn signal does not work anymore … if I turn off the ignition makes the motorcycle think such a safety check for the alarm system by all four turn signal light … they do with me also. Right turn signal switch and the turn signal blink, But if I act on the left there garnix. Wiring I think I must be right, otherwise if ignition from yes not all 4 turn signal flashes would blink n. Can someone give me a tip on what it might be or what I could look at? Would I be happy about an answer
