Electrical problem with dipped/remote light

A hello to everyone, since yesterday I have a small but not quite insignificant problem with the light. The main light works, but the dipped light does not. And before I start to take apart the Harley I simply ask here. Illuminants does not renew success, then measured: With me it is so switch position dipped light : yellow cable leads current switch position main light: yellow and white cable leads current Shouldn’t that be the case? What is the difference between the light and the light? it has to conduct electricity when I switch off or main beam. or must the yellow lead on one and the white lead on the other. If it were a cable break would light up anything at all? Ask nothing but questions. But maybe someone has a clue.
