Have an electrical issue with my 2013 sedan M6 and electrical is definitely the weakest tool in my tool box. Battery is draining down overnight (New Battery) so I ran an amp meter between the negative post and the cable and it is drawing over 1 amps. I let the car sit for an hour before testing and made sure everything obvious was off. Started pulling fuses and relays in the trunk and under the hood and the only one that made a difference was under the hood, #36, which controls BCM 2, dropped down to 0.15 amps. Anyone know what BCM 2 controls? The only electrical mods on the car are the cutouts and the radar detector wired into my rearview mirror.
