Need some help here. My 2004 STI keeps draining the battery in a matter of a few hours and quickly enough to prevent a start after two minutes of connecting the battery. I pulled all the fuses and found SBF-5 to drain my now almost dead battery from 5v to 2v instantly and it continues to drain from there.
My clock also draws it down fairly quick. There was an aftermarket stereo and sub/amp installed that I went through. Amp and sub are removed now. The gauges are pulling power from the removed clock wires and grounds go to battery.
It died yesterday idling. New battery and alternator last month. This has been going on for almost a year but car is always parked while I travel. I maybe drove it twice this year.
Disconnected the 4 relays on the passenger side and still get SBF-5 draw. Checked draw at fuses 11, 13, and 18 as I saw somewhere on here and there was nothing. So something is still pulling it down. I am the worst at using a meter so will need all the help I can get!
