[Elecraft] KX3 Vehicle mount

Ed,

Yes, eliminate the fuse in the negative wire and ground it to the 
chassis near the point where the battery negative is grounded.

Consider that the radio will also be grounded by the connection of the 
coax shield to the chassis.  If the negative power lead is fused and 
that fuse opens, current can still flow to the radio, but by a very 
circuitous path and that is not 'goodness' .
