Default ranchero dead short

I converted my 64 Ranchero from a generator to a one wire alternator. Followed directions to the letter. Now I have a dead short on the taillight/brakelight/dome light. Key on, key off does not matter, as soon as i touch a fuse to the clip, it blows.I have looked at all of the light sockets, bulbs, and have inspected as much of the wiring as i can see and all are in good shape. i did leave the old regulator in place but do not believe it makes a difference. Tired of laying on cold floor, need help. Thanks.

Default dead short

problem did not occur until conversion. alternator and conversion kit came from falcon parts.com, no other work took place.

You state a one wire alternator, correct ?
There should be more wires coming off the alt, otherwise how does the alt know when to charge, increase or decrease charge output . Is this all supposed to be built into the alt based on voltage present at the one wire? What did you do with the wires coming off the voltage regulator?
