[Elecraft] K3 power supply fuses

[John, 9H5G]

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?
