The best method is Wayne's suggestion from way back: In both Neg and Pos leads, supply a fuseholder and fuse. I use the "stubby" fuses from Motorola @ 30A, you should use something like that. These are T-rated, meaning they're designed to open with a DC load. Don't use a fuse out of your home's fusebox...
General setup: 12V AGM Battery @ 110 AH, cabled to a set of panel-mounted MOT inline fuse holders. Each lead is covered by a 30A fuse. The battery is charged by solar power, two Siemens SR50 (50W) panels on the roof of the shack. Note: This recommendation is a little more permanent than what you're probably looking for right now. If you're interested in this approach, I can probably get you the part numbers you need. MOT has a service center in IL, and you can phone in your order. 73, matt W6NIA On Wed, 11 Aug 2010 16:32:12 -0700 (PDT), you wrote: >Hi, I am ready to apply 12v for the first time to my new K3.
