      Comments about ST Blade Fuse Blocks:

      I was down at my boat and was wondering why my stereo, ship to shore radio, spot light, interior lights all stopped working at once, I have a 20ft trophy with a hardtop and a compartment where the radios are, I grabbed a wire on the fuse box to see what would happen if I just jiggled it a little, needless to say now I'm holding the wire in my hand, I went to west marine in patchogue Long Island and an older gentleman that worked there matched up my old fuse box with a new one explained every thing to me and even showed me wire connections that I needed to hook up my wires to the new fuse box,after I was done I turned the battery buddy on and everything went on the stereo the radio my lights I couldn't believe it and the best thing of all I didn't have to go back to the store because it was the wrong part, hats off to that salesman he knew his stuff.

            Replaced an old glass fuse panel that was large and rusty. This unit is much more compact that the old unit. This has an easy to remove cover and holds two spare fuses.

                Fuses are found in all auto part stores. The fuses are color coded and stamped with large print for amps. The fuse blocks well designed.

                  I installed a 2003 model 5.3 liter Vortec engine in a classic truck and needed a fuse block for the computer, fuel pump, and sensors. I bought the Blue Sea fuse block (12 position), and I couldn't be more pleased. It is compact, well built, and easy to wire. I recommend it to anyone.

                      I am a marine electrician and electronics installer. I use these on a regular basis since I often work on trilerable boats with mediocre distribution systems. They are easy for my customers to understand and use if a fuse blows. The fuses are easy to identify, unlike the glass vial SAE type.
