Happy to have helped!

I agree with what youre saying but its not just a matter of the load activating, if you have a high amperage load and get a small short to ground, the heat created at that point would be problematic. And theres not much you could do as far as fusing that so youre kinda sol.

Thanks Tom. The only reason I didn’t do that on a few of them was to have the 86 only hot when the ignition is on since I was powering the buss with battery hot. But I agree with the principle totally.

@@MattsGarage can you explain that a little, best video so far to explain a relay ive found! I want to move the rats nest of wires from my interior fusebox to a relay panel but I only want power when ignition is on... TIA!

@@davidokner5450 thanks! What I was trying to explain was that if I was powering the whole panel with switched ignition, the. I could jumper everything 86-30. Then it only needs one wire to power the whole the panel and cleans up a lot of wiring. But I have that panel on Battery + and I don’t want the 86’s to also we battery + I want them on switched power. In case something grounds out in the middle of the night from a furry beast chewing on the wire, it won’t burn the whole rig to the ground.

@@MattsGarage Hi, so instead of running the power directly from the battery I'd run a wire from the ignition switch itself and that would be my connection to the 30 blade or main power cable, correct? thanks!

@@davidokner5450 hmmm. No it would be from your ignition to the 86. If you run ignition to 30, then whenever the switch to ground on 85 opens, you are powering your device through your ignition switch. That could be ok for things that require only a little amperage, but anything that draws a lot of Amps should (in my opinion) be battery + to the 30. The only debate is whether to power 86 from battery + or to power 86 from ignition hot. I was just saying I prefer the latter but I admit the former is cleaner in the sense that you have fewer wires running to the panel. BUT that means all of your relays must be switched to ground (switch on the 85 side) and if any of those wires ground out the load will have power. I would recommend just grabbing a 12v light, a battery and a relay and just trying the different setups on a bench. It might give you more of a feel of what’s best for you.

Thanks Sean!

Wow that’s a great compliment! Thanks!

Thanks Nick!

I still haven’t actually properly mounted it yet. It works great but still need to mount it permanently. I believe the standoffs were 3/4” but I got rid of them. It was a pain.

You can put the switch either on the 86 side or 85 side. I don’t remember sending ground to 86 but it “should” be 85 to ground. However, I don’t think the relay cares about that either.

I mounted them inside so I didn’t bother. Unless you are fording water it’s not necessary

Thanks Chris, glad it resonated!

If I’m understanding your question, yes.

@@MattsGarage 10-4 just trying to figure out how to wire all my accessories I have the same box as in video and in the past bought a regular fuse box like a 12 channel wanted to run power to fuse box then from there run to relays I understand it would have 2 fuses would that affect anything

I'm pretty sure I used a 10.

Is the short in the relay or the wiring? With the car turned off you'd put your multimeter on the wires coming to and from the relay one by one and put the other probe on a good chassis ground or the negative baterry terminal. Obviously not the ground wire as that one would have continuity by design. You could use the continuity setting or ohms. If there is any continuity, or if the ohms are low, then that's your short.

@Matt's Garage big thank you for the reply and video

It really depends on the amp draw. Switches and fuses will work, but then your putting a lot of amperage through the switch. The relay avoids that as there is very low amperage required to trigger the relay. It's like the trigger on a mouse trap. A little force unleashes a bigger force.

@@MattsGarage i calculated a total of a bit less than 40 amps for all accessories. what do you recommend?

@@yasser.busaleh I’m not the right person to ask. I put a relay on everything more than 8 amps but you could probably go up to 15 per circuit. your LED light bar is the biggest draw right? You should put relays for the biggest draws.

Depends on what you are running. There is not 1 correct answer.

Theoretically, yes. They all do bascially the same thing. You just have to know/pay attention to the way it's pinned/wired. If it's just one relay you can just buy a single relay holder as well, probably easier.

@@MattsGarage Thanks

What kind of wire are you using? I didn't have an issue but I use GXL wire which has thinner insulation.
