Parasitic Drain

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?

A 200 mA drain isn't much. It could just be the computer. Chech your starter solenoid to make sure it isn't leaking power through the contacts. It might not be opening completely.
