Hazard Warning Switch
Remove hazard warning switch. With hazard warning switch in OFF position, continuity should be present between switch terminals No. 7 and 10. See Fig 1. With hazard warning switch in ON position, continuity should be present between switch terminals No. 7 and 8. With hazard warning switch in either position, continuity should be present between switch terminals No. 2 and 3 (illumination circuit). If continuity is not as specified, replace hazard warning switch and retest system operation.
