Unknown Battery Drain

[beachbum]

I have a 2000 SSEi with about 97K miles on it and I'm having a problem with a dead battery after a few days. I have replaced the battery and have had Advance Auto run a check on the electrical system and they tell me that the battery is OK, the alternator and starter are OK, but there is a 1.9 Amp discharge on the battery when the engine and ignition are off. I have checked all of the battery and fuse box connections as well as the ground to the battery. They said the symptons indicate a loose or corroded connection somewhere. I don't hear or see anything running when the car is off but my wife tells me that she has been getting intermittent "Service Security System" messages on the DIC. Has anyone else had this same type of issue?
Once I jump the battery, the car starts and runs fine and will start again but goes dead after a day or two of not starting.
Any help or ideas would be appreciated since my next step is to take it to the stealership for their diagnosis....
Thanks

The draw should be more 25 milliamps. Start pulling fuses, one at a time, and see which one causes the current draw to drop. Now, you've at least limited it to the circuit.

i agree put a amp meter between the red battery terminal and the wire to read the draw then start pulling fuses till you see the drop

i had this same problem on my 94 explorer and it was a $10 relay that was staying on with the ignition off

so you just gotta find what is staying on then replace it lol

good luck
