I'm not completely sure I understand where you are measuring voltage, but if
the red wire with +12.5v is on one side of the fuse, and the red/blue
wire with 1.6v
and dropping is on the other side of the fuse, your problem is almost
certainly a
bad fuse.  Likely it conducts some electricity until it heats up, at
which point its
resistance increases causing the drop in voltage.
