Roy and the group,

The reason for the negative lead fuse in the mobile hook up is to save your

Consider if the starter ground return to the battery, (The negative battery
cable), came loose, became frayed, and parted; then the starter current would
run through the antenna ground to the car, up the coax braid, and then through
your radio's common cable, and back to the battery.  Likely, internal negative
wires of the radio would be the smallest gauge of all these and would melt.

A good quality fuse and holder will not reduce the voltage enough to matter
more than this safety precaution. 

All the Yaecomwoods come with double fused DC cables now for this reason as do
the commercial radios for other uses.
