The whole injection system (Pump + Sparks + Stator = ECU controlled.) (If the stator is toast, the ECU won’t allow sparks to happen)
Fuel Pump draws a LOT of power , so it will have its own 4-pin relay yes. OR 30A fuse (depends on harness part number) = Hyosung did many subtle changes on their EFI machines so there will be a box that says GREEN 30A or simply 4-Pin Relay (20/30A)
Headlights = Right Switch Gear (very early EFI models or carb models only) , Left Switch Gear and 4 Pin Relay
Tail Light = Sometimes depending on the “main” harness , it will share the headlight relay. So if the headlights are on, so should the tail light. I’ve done this a few times on a 2017 machine, as soon as i took off the main headlight relay , the tail light turned off.
High Beam Button (left switch gear) & “yellow Pass Button” on left switch gear = All share the same yellow wire going in to the main harness and the same yellow wire is going to the LCD dash to trigger the blue icon that “H1” bulb is active (high beam)
Meter on “ground” or battery negative and yellow wire ==> Press high beam or Pass Button => 12v should be active on the yellow line at the H1 bulb.
Make sure all bulbs are 55w max. (I’ve seen owners put 100w 24v, and everything just cooked slowly)
Low beam should be always on as soon as the key is turned regardless if the dash is present or not, so this will be a bulb , harness issue or relay. 12v needs to be on the bulb connectors ofcourse. The low beam also serves as “day time running running” , much like morden cars. Older Hyosung carb models didn’t have this feature, we actually could turn the lights ON / OFF via the right switch
EFi = changed now, the right switch doesn’t turn headlights off , it just triggers the “hazard” lights hence the Triangle symbol now.
Brake Lights = They are only triggered by the levers only. (brake pedal switch & hand lever switch)
