no headlight and no start. the starter switch is bad. the switched needs to be removed and cleaned and also the guides for the shunt need to be fixed. the overheating of the switch melts the plastic guides and prevents the shunt from sliding up and down. it sticks in the down position and stops the headlight ans starter from working. when you get the switch working again you should put your headlight on a relay to remove the power draw through the switch.
