lost headlights,horn,blower motor,signals and other stuff the other night. bench checked the load reduction relay and it was fine so i changed ignition switch. worked fine after installation but now the minute i try to turn headlights on the whole circuits triggers off for like 5 minute and then restarts.only when i turn headlights on. the other items like blower motor ,signals ,wipers can run at once until i include the headlight switch. then everything triggers off again. seems like a short somewhere. im stumped! please help! thnks!
