And that is exactly what I did, just as you said earlier:

"The original choke was fed off a black/white that went to the "s" terminal of the alternator."

My wire is fed straight from that "S" terminal on the alternator, with an inline fuse, straight to the choke element. I seem to have made an error in earlier post, saying "F' instead of "S".. My apology. I can take a pic of it and post it so I can make sure it is the right one?
