WHILE DRIVING ON THE INTERSTATE ALL OF THE GAUGES QUIT WORKING. WHILE ATTEMPTING TO PULLOVER THE HORN STARTED TO BLOW AND THE LIGHTS STARTED GOING OFF AND ON. I WAS ABLE TO PULLOVER BUT THE TRUCK WOULD NOT TURN OFF. A SHORT TIME LATER MY WIFE SMELLED ELECTRICAL SMOKE. I OPENED THE HOOD AND THE FUSE BOX WAS ON FIRE. I WAS ABLE TO EXTINGUISH THE FIRE AND THE TRUCK WAS TOWED TO MUSIC CITY DODGE IN MURFREESBORO TN. AFTER TWO MONTHS VEHICLE WAS REPAIRED, EXPLANATION BY DEALER WAS BATTERY CABLE NOT PROPERLY INSTALLED AT THE FACTORY.
