i mean unless the wire was disconnected at the fuse junction or wherever it starts then i think the fuse should be checked first.
What happened in my case was that the plastic clip at the end that connects to the choke cover fell off,
2) i switched carbs to one that uses a hot air choke, not an electric
3) i left the wire just hanging around there. (should have taped over the end w/ electrical tape....)
4) The wire, apparently, touched the valve cover; This was apparently too much voltage and the fuse blew.
5) i then decided to switch back to the original quadrajet, because i didn't really know what i was doing as far as swapping carbs.
6) After switching back carbs, the choke light came on and stayed on.
It was the fuse. And yes, i have an 83 c-10 which is basically identical to an 84.
