2005 XF Roadster, with loss of top and spoiler function. No. 7 fuse blows, before anything is turned on, including ignition. The paper inside the acc. Fusebox says that's the fuse for the "central control module" by which I think they mean the BCM. I find no short in the relay module box. Wiring to top motors and sensors looks ok, to gross check.

I'm afraid to just replace the BCM, because it seems there is a short to ground somewhere. Where should I look, or could a bad BCM blow the fuse. I have looked in the archive, but don't find anything about the fuse blowing with a BCM problem.

I'm a newbie here, and would like to thank everyone for their efforts. This is an amazing site, with a HUGE amount of valuable information. Thanks!!!
