I have a '07 Expedition with a battery drain. Hooked a meter up to it and after a couple mins the meter will show the truck is in "sleep" mode with a low mA reading. About every 30 secs the meter will jump to between 7-9 Amps for about 3-5 secs then back down to a low mA reading. Cant remember the actual low number, even reading 0. Even before the truck enters "sleep" mode the same cycle is going on, just the mA aren't as low of course. I'm thinking this is the smart junction box, but didn't have time to stay at my friends house using the meter to pull fuses. Also I was trying to find out what fuse number the SJB is. Any help please? Or ideas if I'm on the right track. Thanks!
