Help! Cant find electrical drain.

[Arl37]

69 chevy c10 with new crate 350. Draws .29 at battery post. Disconnected every fuse and every unfused plug I could find (ignition,headlights, wipers, coulmn connecttion ect). Only if I remove two spade connector at top of alternator does drain disapear. New internal regulator alternator. If I put yellow wire on spad with the number 2 beside it and the blue wire to the spade marked p, the drain drops to .01. I thought this set up was backwards but the ammeter in the car still shows charging when running with this wiring. Did I have the wires switched or is it something else.
