ONLINE LED STORE6 Way Blade Fuse Box with Ground Negative Bus bar for Automotive [ATC/ATO Blade Fuses] [100 Amp] [LED] [Protection Cover] [12V - 30V DC] Auto Marine Ground Fuse Block

Nice price, great function and form factor. I used the 10-way and 6-way for front and back of my van build. When everything is wired up and there's a load drawing current, the LED will light when a fuse is blown or pulled and the circuit is broken. I measure ~3 V on the panel in this situation (with ~13.6 V on the input).The root cause of my trouble with this fuse box - and I noticed another reviewer sees it too - is there measures ~11.8 V on the panel (same 13.6 V input) with an open circuit (blown or missing fuse). A gooseneck reading lamp (LED) that I installed for my wife was not working properly, and I went through a hassle to run down the wire assuming the shy voltage was a bad crimp or connector. (In fact, this issue prompted me to buy this second one for the rear wiring of the van... not that it broke the bank).It just so happens the LED reading lamp draws just enough current with the fuse blown (due to the voltage drop) from my Battle Born batteries (at 13.6 V charge level). I also wired a 12 V DC power supply that takes over from the batteries when the van's plugged into AC, and I didn't measure the actual voltage drop but the reading lamp won't flash in that configuration (I assume it just can't draw enough leakage current).Bottom line: made for some painful debugging to assume there would be no (or insignificant) leakage current with a fuse blown. Make sure you have GOOD fuses installed as you test all your circuits, because a blown one may not light that red LED on this panel as advertised.

I bought this to install gauges in my track car. Great price and simple to install. I like the LED lights to indicate when the fuse is busted and integrated neg bus bar makes things easy to install.*Note about power draw when fuse is blown*People have been saying that they are getting near 12V even when a fuse is blown but if you read the instructions this is done at a very low amperage, just enough to power the small LED but not enough to power anything else or cause a short.My only critique is I wish it was a flat back so i could use double sided tape instead of having to use the screw holes.Either way I recommend for a budget set up.

only 1 issue for this, that I did not catch until my boss looked under the dashboard - there needs to be an INSULATED-CAP to protect the +positive Lead, mine was 1 kick from frying my fuse off the battery ...all and all good fuse block makes some hiss on my LED off-road lights, i had to fix this by using a Relay off the battery, (im not an expert but any time the switch / or lights was on the block, 15Khz tone ran thew the speakers, fixed by taking it off the fuse block "not a grounding issue") no other issues with my inverters or epicenter/eq/stereo/backup-cam/

great product works well, compact & easy to install & use...

Used in a small tractor, perfect
