Sorry with my English.

Hi Kaldaz,
basically you have 2 circuits on the bike. One AC-Circuit and one DC-Circuit. Both start from a yellow wire (generator). The AC-circuit powers your light, while the DC-circuit powers your battery and in consequence your turn lights too.

The coils for the DC-Circuit in your stator could be broken (short cut). You can test that when you exchange the "yellow-cable-connectors" --> when it's broken, your headlight will not light up.

If that's not the issue, maybe the "regulator/rectifier" is broken (the thing below the big rectangular frame pipe, that has 4 connectors but only 3 are used - brown is ground, yellow comes from your stator, red/white goes to your key lock and therefore finally to your battery). I guess you can measure the voltage between red/white and brown using a multimeter.

Often a common reason - bad ground connection. Your bike already is some years old, so check all ground connections! Even the battery-to-frame-ground!

Hope this helps a little,

Start simple ground/earth clean as needed loose connections. Where do you have power and don’t you have power? Eliminate the easy inexpensive stuff first.
