I always fuse both sides of the radio circuit, recall reading somewhere that it 
was a good practice to fuse both the positive and negative leads of power to a 
mobile radio so if for some reason the ground connection between the starter and 
the negative side of the battery was lost, and you had the radio also grounded 
to the chassis, you would be protected from a big current surge from the starter 
trying to find its way back to the battery negative through the chassis and the 
radio wiring.  I believe this was mentioned in the install instructions for my 
Yaesu FT100D among other places.

Christopher,

Don't waste money fusing the A- lead.  The DY-88 is a negative ground (only) 
unit and A- is tied to chassis in both it and the RT-77/GRC-9,
