I have a recently restored model 116 and the lights have worked until last week. I am not very good with the electrical parts and would ask for a place to start to diagnose the problems. It has a lighting coil, Femsa points stock ignition, and four wires coming off the magneto/ignition. The wire colors are black, yellow, green and red. Any assistance is appreciated, but please type slowly as I am not good with the electrical..........😁
