I think I have parasitic drain!?!?!

[Bane]

Recently my 2001 3.0 X5 has been losing battery charge and I have had to jump it 3 or 4 times over the last month. 3 nights ago (during a rainstorm) it started up then the dash and all the electrical started flashing and barely working. I drove it a bit and it seem to charge back up and when I got it home it started the next morning and there was a long hum behind the climate control panel and then later it would not start. I started researching the forum and see that this common(ish) problem. I have had the X5 on a charger and it now starts back up and when I turn it off there was no hum. I see that the FSR is a many times the issue as well as I have had issues with the tailgate top not always opening when the back release is pushed.

My question is can I drive pull the FSR and drive around for a few days with out it to see if that is the problem?
