Review on 💡 High-Performance Sierra FS40440 Fuse Block by Cole Hersee for Reliable Electrical Protection by Jason Hayes

I installed this on my boat to replace an old fuse and get more fuse slots. At first this seemed to fit. I managed to tidy up the wiring under the console and hook up all my devices. One of the devices is an echo sounder. During my first ride the sonar turned on and worked, but as the boat went through the water the sonar turned off. I found the problem was the positive connection to that fuse box. It got loose. So I moved the connection to the second port on the fuse box. It worked for a few months last summer, then the same thing. The sonar just goes off. Again, I know the connection on this fuse box is loose because if the boat doesn't move it's fine, but if I wiggle the wire a little the metal tab moves and the sounder shuts off. So it's a nice design and just what I need, but it doesn't seem to stand up to the boat traffic. Looks like I'll have to find a better product and replace this one.
