John, out of curiosity.What size wire you are using, and how long is the wire
between the Radio and the Battery?
PS: Contrary to what some believe, the FUSE in a power cable is not there to
protect the Radio.
But there to protect the " Power Cable " from starting a fire.

You might closely examine the type of connections inside the holders. Some
aftermarket automotive fuse holders have poorly crimped connections and
might pass a quick resistance check, but....

Subject: [Elecraft] K3 power supply fuses
My K3 is powered from a car battery as I am always /P. I have installed
fast-blow fuses rated at 25 A in each of the supply lines.
Operating at 80W RTTY this afternoon, I noted that I was getting a low
voltage warning before I would have expected it. On examining the power
cable, I found the fuse holders to be warm to the touch. I expect that is
what was causing the voltage drop.
However, may I ask what specific (make , model) of fuse holders are you
using to protect your k3?
