Seems like you have a short somewhere in that circuit. As you’ve disconnected the wires that go to headlight switch (if you have it) then perhaps you’ve been into that hand control and pinched a wire or something?
otherwise look for frayed wires in the headlight bucket and also broken wires at the neck of the bike where the main “trunk” of cables pass.
I also had one bike with a problem inside the speedo gauge cluster causing that same symptom.
The orange / orange white (power to lighting circuit) wires are what I would be tracing.
use a wiring diagram for your model. Bon Chance!
