ok, here's the problem, key turns and all it does is buzz, no crank, nothing. I had the battery tested and charged and it's fine, changed the ignition switch, put new battery cables on there and had the starter checked and it's "supposed" to be fine. still nothing, however when I try bridging the battery terminal to the motor terminal on the starter, it started cranking,,, problem was it wouldn't stop cranking, it did manage to start but i couldn't get it to stop cranking till i disconnected the battery, and then it was smoking, (the starter). anybody got any ideas as to what it could be now? neutral start switches? wiring? any ideas?
