I've got a parasitic draw of about 250 mA that I'm trying to track down. I set up my multimeter and ran through the fuse fox but I'm not sure how to check the fusible link. I see fuses in there but they don't appear to be removable. Is there a good way to test each of those circuits? Open to other suggestions as well. Thanks.

Fusible link is a basic fuse encased in rubber, like a glass fuse and it's ON or OFF. You test them for OPEN or BLOWN. Parasitic draw in the G varies from model to model. My drew about 375mA for 20 minutes then went down to 85mA. I had a 07 G35 5AT with BOSE audio and Navigation and front cruise radar. I did ditch the OEM navigation and replaced it with Aliexpress android radio, i've heard those OEM 'hard drive' driven radios can create power draws.
