Found a draw, unpluged the alternator and the draw went away. Took the battery and alternator to a shop and they both checked out to be good. The problem is intermittent. Where should I begin?

There is no quick way. cheeck your glove box light to make sure it is going of. Pull one fuse at a time, to see witch cercuit the draw is on. Then cheeck out that cercuit.

it still could be the alternater ford uses a "cs" style unit its sorta like a generater in that it must create a magnetic field around the winding to charge. kinda like having to prime a pump to get it to work. anyway when the windings get week and start to break down the unit will still charge but when at rest it still draws power from battery ( a cs style alternater can be damaged by unpluging the positive battery while it is running) you can not test it like the old style ones. use an amp meter while turned off check at the battery wire on the back of it there should be no amp drawl on it.
