Question about 1978 Yamaha XS 500
Have you checked the ground side of things?, to complete an electrical circuit you need ground. try running your own external ground directly from battery neg. post to individual components . that will tell you if it is pos. wires or neg. wires are good or bad.that is a very old bike,check harness ground to frame and motor for rust and corrosion,check all connections and clean and scrape shiny again, but do not bend or break connector pins.as a last resort you might consider fabricating or buying wiring harness if in very corroded & dry rotted condition.
