[Elecraft] K3 Voltage drop

[Vic K2VCO]

One of the more common sources of resistance are the various 'DC distribution' devices. 
They put at least two additional connectors and sometimes switches and fuses into the 
circuit. Also cables with inline fuses often add excessive resistance if the fuseholder 
isn't high quality. Incidentally, in a fixed (not mobile) application, only the positive 
line should be fused.
