Audio Fuse #62 is causing parasitic drain on 98 Max SE (> 200ma). By tracing the schematic diagram, it goes directly into Bose headunit pin 6 - BackUp. Is there anyway to correct this? The head unit is working fine, playing radio, CD and tape without issue. Some suggests spraying electronic cleaner into the internal circuit while it is disconnected, let dry and hope for miracle.

Have you had similar issue and how did you fix it?
Is there any way to save the HU?

 

15A for 'bat backup'? When I removed fuse #62, the HU did not power up. Strange.
Thinking of couple hacks
. add a kill switch in between, or
. splice into ACC (pin 10), up fuse #21 and hope wiring is capable for extra load, or
. relay power, still through fuse #62, using ACC as switch signal, or
....
