02 LeSabre 3.8 K...

02 LeSabre 3.8 K motor. 126mA parasitic Drain from ALDL fuse #4 under back seat. Car runs without it but I am wondering what it powers beside a scan tool. I don't have a schematic here at home to ck.

Mechanic's Assistant: Have you checked the vehicle's manual?

Not Present

Mechanic's Assistant: Are you fixing your LeSabre yourself? What have you tried so far?

Trying to help out an older lady that has been through a lot lately. Battery keeps going dead after a couple 3 days I'm told. Battery good. Alternator good. Disconnected engine compartment fuse block, then back seat fuse block. Pulled maxi fuses, alt wires atec. Eventually traced it to ALDL fuse. Nothing plugged into ALDL I see. I have not went under dash yet to look for aftermarket or used car dealer attachments. Just wondering what will be lost without fuse 4. Everything seems to work. But a scantool will not get power.I usually don't work at Home. I have schematics at work. I teach at a tech school.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No. I'll figure it out. just wishing I knew what all that fuse powers
