2007 9-5 100 milliamp parasitic draw on maxi fuse 2

I replaced the alternator, battery, and starter! I went to start my car this past Sunday, and nothing. A local mechanic discovered there is a 100mA power draw on the maxi fuse 2.

This is what they wrote up:
---

REMOVINGFUSE 17 RESULTED IN FURTHER DROP OF POWER DRAW.
FUSE 17 RUNS MAIN INSTRUMENT UNIT (DASHBOARD INTEGRATED CONTROL ELECTONICS MODULE)
Cause -

CUSTOMER RECOMMENDED TO REGULARLY DRIVE CAR, UTILIZE BATTERY TENDER WHEN PARKED, OR

Any thoughts on what it could be? Would the SID module affect this? There are no interior sounds (turn signal, open door, etc.) The trunk light is off, and I turned the interior lights off. Or is a cut-off switch my best/cheapest option?

Thanks,
Jeff
