Review on WUPP Waterproof 12 Volt Fuse Block With LED Warning Indicator For Car, Marine, RV, And Truck - Includes Fuses And Negative Bus Fuse Box by Ryan Reiter

When I got this, I was pleasantly surprised because it seemed well made and designed. I spent a couple hours wiring everything up to it, turned on the power, and seemed like it worked great! Then I decided to test what happened when I removed a fuse (to simulate a blown fuse). Insanely, when this happens, the "blown fuse” indicator does light up - BUT - there is now 2-3V present on that circuit! Meaning it’s still connected to power! If the output of the circuit is not connected to anything (I.I. You have a switch wired up and it’s turned off, the voltage at the fuse block side of the circuit is 11.7v! Also insane. This is a huge design flaw, and very dangerous. It can definitely damage electronics connected to it. I have no idea how a company can possibly design a fuse block that works this way, the entire purpose of a fuse block is to cut power when a fuse is blown it removed.DO NOT BUY. Waste of money. Stick with a quality name brand like Blue Sea Systems. Learned my lesson this time.
