Tell me if I'm doing this right with my multimeter (UPDATE)

Yes you are reading the meter correct. The draw is what it is and even described in the manual. An alternative to the fuse would be a small charger on the battery for storage such as Battery Minder or Battery Tender brands.

You could have it checked at the dealer but I doubt they would know what is normal. They would just give you a half baked look like you were another crazy customer. Then they would take it in and charge $150+ to tell you all is normal.

If you have a buddy with same car you could compare numbers.
