hi arty b- thanks for your erudite reply. will check fuse 5 for salt deposits, swamp rats gnawing , corrosion corroding and cockroaches crunching. but wait are the directionals and 4 ways on the same circuit or separate circuits? some cars have separate circuits for the 2 flashing systems . surmise that is for safety purposes in the event one system is disabled, the other can still be used if the car is disabled or piled up on the edge of the creek. this would warn approaching coppas or other marauders to avoid plowing into you. wouldn't the single fuse if crapped out prevent power to the hazard 4 ways too? I must be missing something here. will report on the fuse check. thanks ton oldduke
