  Hello everyone.
  Someone give me some advice.
  The starting problem of my engine (Hyosung GT650n EFI) is solved, but now something new has appeared.
  When I turn the key, there is a sound as if the stall indicator is flashing (knocking sound).
  The sound stops when I remove the diode near the fuses from the back.
  What could be the problem?
  
  I should add that the motora led index and I installed a lamp.
  So far there has been no problem with it.
  Maybe the problem was that I washed it in front of him?

  If you have LED indicators , you will need 3Pin LED relay.
  
  If LED relay is faulty ; replace it.
  
  If you have standard bulbs, (original hyosung indicators, then let us know?)

  It has LED displays, a 3-pin LED relay has been replaced with a new one.
  However, when I remove the zener diode, the problem does not occur.
  There is an index left and right.
  Only there is no jam indicator.

  Hi Everyone.
  I found the source of the error.
  It was really the electronics that were at fault.
  More specifically, the left steering wheel switch.
  The soldering place was twisted, almost all the cables.
  Where there was soldering, it was weak.
  The current owner is doing a lousy job.
  It took a whole morning to fix the error.
  The cable harness gets a place for the insulating tape, a rubber cover, and a waterproof adhesive.
  Look at the miracle, the dragon works beautifully.
