Electricals Again (Radio)

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.

Hi Ales,

I'm actually measuring from the fuse panel.  What I did was, take the fuse out, 
measure from the fuse terminal to ground and I get 12.5v and no voltage drop.  
This is where the red wire goes in.  


I then measured from the other terminal to ground.  This is where the red/blue 
wire attaches.  I see a steady voltage drop here from about 1.6v to about 
20-22mV in about 20 minutes.  


Putting the fuse back in seems to "energize" the circuit.  But what is strange 
is that if I leave the fuse in, come back in 20 minutes or so, pull the fuse and 
check voltage from red/blue to ground I get about 20-22mV.  So I'm not sure 
what's going on here.

Don't know if that makes sense?

So, in order to get the radio working, I pretty much have to pull/push the fuse 
every time.
