hello, my name is michelle, i have a 94 mustang that has a 4.5amp current draw on the eec circuit when the key is off. i have disconnected all the wires on the alternator, all the fuses for the hood lamps, dome lamps ect. the 20amp fuse for the eec under the hood seems to be where im getting my draw from. when i pull the eec fuse it drops to a few miliamps. it seems like the computer is staying powered on at all times. i even disconnected the ignition switch harness under the column, and the ccrm harness. i dont see how the eec circuit can still be drawing power if the relays are disconnected?

i have most of the diagrams but i was hoping maybe some of you guys might be able to help a lady in distress. im at a loss here, i need my car running so i can get to work! help!

4.5 amps is a BIG parasitic draw. It is completely normal for the PCM to draw a few mili-amps all of the time.

How did you measure the current draw? Did you also test pulling the fuses in the I/P fuse panel inside the car?

Has there been any work done to the car? New audio system? Sub amp? After market lights? Alarm system? Navigation system? Anything running from the 12 volt power outlets (cell phone chargers, DVD systems)? Speedcal?

Is the top of the battery clean? Are the battery cables clean and tight?

I suspect that you have not identified the fuse that is actually causing the problem.

If the draw can not be traced to a fuse, then have your alternator tested. Any autoparts store will be happy to test for free.
