2118 Ford Explorer XLT. I'm trying to find the source of a parasitic drain. After following shutdown procedures, I pulled every fuse and relay in the distribution box and under the dash. It still has a 200 mA drain with no fuses in the boxes. I've checked the alternator and the diodes are fine. The only way to eliminate it is to disconnect the smaller cable off the positive battery post, which I assume feeds the computers. Any suggestions from the group?

The computer does need power. The clock and radio presets will draw a tiny amount (like 200 ma). Is the battery running down too fast?

Ford specs say this car should pull a maximum of 50mA after system shutdown. Mine is at 200 mA which leaves my battery dead in about 3 days if not used. I'm assuming the computer is not going into "sleep mode" when sitting idle.
