I recently purchased a 12 volt plugin adapter to charge my iPad pro through the 12 volt auxiliary charger located next to the radio on the helm deck.  It appears that the adapter which was sold specifically for the iPad pro has blown a fuse on the 12 volt power lead that supports both the auxiliary charger and the stereo head end on my 2009 Sovran.
 
I checked the fuse on the stereo and it is OK.  I checked the panel fuse marked stereo and it is also OK.  I can see that the 12V power lead is split to support both the stereo head end and the auxiliary charger.  I have followed the harness as far as I can see and cannot see any additional fuses.   
 
Assuming there is an additional fuse can anyone tell me where to look for it?  Do I have to pull the microwave unit to provide more access to the back of the helm deck stereo/auxiliary charger mounting points?  If so can you provide some guidance on its removal as it appears that the mounting bracket for the microwave is screwed in from below with no access unless I pull out the refrigerator??
 
Any help the forum can provide is greatly appreciated!
