Rear running lights and brake lights went out.  And now the headlight went out. Fuses and wiring are fine. Anyone know how to fix?

Rear tail lights are on F16, 10A, rear brake lights are on F13, 10A and the head lights are on F11, 20 A in the fuse box that is under the front panel on the hood. If the fuses are good than the wiring may be good and not chaffed to the metal somewhere? Did you check the bulbs?

If the bulbs are burnt I would check the charging voltage when the engine is running to make sure your voltage regulator hasn't failed. Charging voltage should not be above 15 Vdc at 4000 RPM.🙂
