Explorer Race GT 50 pears burn through

Hello people, with my scooter burn the speedometer lighting, dipped light, brake light and the 2x3W glass-socket bulbs for the stand light at speeding through, in the stand the bulbs flicker when I give gas as first tacho then rear light then standing light bulbs and at the end the dipped light through. CDI, light anchor plate with pickup and voltage regulator are new .. the funny is that the fuse on the battery does not melt … now I have the light resistance in the eye 30W 5,9 Ohm … how do I measure the one with my multimeter in the jammed condition ? How much ohm does he have to show me when he’s healed ?
