71 dart instrument cluster

well i installed new solid state limiter. bench tested the whole instrument cluster and everything worked. Then i putted it in car and nothing worked, even not the turn signals wich worked before. no power to anything, when starting it would crank for like .5 seconds. In one point it started smoking somewhere near light switch but couldn find any bad wires. Now i Taked the limiter of and everything "works" like it used to. And i noticed one more problem, when cranking the engine i think theres no spark. when i let go off key it will start.
