IMPORTANT UPDATE 10/06/2014: - Beware of your current setup!!!
So after having this setup for a few months I got bit by the cheap parts fairy. I left my RZR in the trailer for about 2 weeks without starting it. When I went back to it to pull it out of the trailer, I turned the key and nothing happened. Long story short, the battery was dead due to a constant 4mA draw from the relay. It forced me to replace my battery as well. My suspicion is that the relay went bad due to the constant beating it was taking. I now have an 80 amp Stinger Battery Isolator Relay on the way. The only downside to this, is now my fuse block circuit becomes an 80 amp max circuit instead of the 100 amp circuit it was previously. I will keep you posted as to the long term testing of this new Stinger Relay. Thanks to Richardson Performance for helping me diagnose this and getting me the parts I needed to fix it.

Over the past few evenings I have been working on installing my accessory fuse block under the hood. I ran a wire from my battery to a 100 amp circuit breaker. From there it goes under the center console (zip tied to the factory wiring harness) up to the larger compartment under the hood into a 150 amp relay. From the relay into my fuse block. The relay is triggered by an accessory wire from the 12v under the dash. Essentially, I will connect all of my accessories into the fuse block and run them to my relay bank (still on its way) to power the accessory. Also have Dunertunes 6 Switch Panel and Upper Corner Single Switch Panels to install. Only accessories to hook up at this point is the Sick-Stikz whip.

nice job.. I did the same thing along with the duel battery set up. the acc fuse block makes it nice to hook up all the crap we put on these things..

It was just a 100 amp circuit breaker from amazon. For around $12.

You can also get these from most larger boating supply stores like West Marine, you will pay more than 12 bucks though but it will be water proof.

I have created a very basic wiring diagram for the above install and also one to illustrate how a dual battery setup might look.

I am completely clueless when it comes to wiring. I have several "stupid" questions that will hopefully help me understand things alittle better and hopefully help other folks who are like me understand things as well.

I have several questions

1) Positive battery to 100 amp circuit breaker --> Is the point of wiring directly to a circuit breaker....when in storage you can flip the circuit breaker to off so your accessories do not drain your battery at all? I assume since the circuit breaker is under the seat you are not flipping it off very often, only in storage because you have to take the seat out (not a pain but you do have to take the seat out)

2) Positive from battery to ignition switch....I assume this is already hooked up and ran from the factory or the ignition switch wouldnt turn the vehicle on?

3) Ignition switch to 100 amp relay --> How do you tap into the ignition swtich wire to go to the relay?

4) Ignition switch to 100 amp relay --> What is the point of tapping into the ignition switch for power when you have power coming from the 100 amp circuit breaker to the 100 amp relay? From the looks of it it looks like the relay is getting power both from the circuit breaker and from the ignition switch, I guess I dont understand why the relay needs power from two sources.

5) 100 amp relay to fuse box --> You have a straight line through all the small holes in the fuse box. I am assuming you bring the wire into the fuse box from the big hole, then you tap into the first fuse, then jumper from fuse to fuse so all fuses have power?

6) jumping from fuse to fuse --> Is it ok lets say if I dont have one of the fuses hooked up because I dont have enough accessories...basically a hot fuse with nothing attached since I dont have an accessory to send it to.

7) 100 amp relay & standard 30/40 amp relay --> If I undestand the purpose of a relay is to simply control the amps going to your switch so your switches do not burn up. If I already have a 100 amp relay going to all my fuses then why do I need a standard 30/40amp relay? It seems like both relays would be doing the same thing?

8) relays --> Just to re-itterate the purpose of a relay is to control the amps going to your rocker switch? So if my rocker switch is 20 amps, and I have nothing that exceeds 20 amps (im sure my light bar is less than 20 amps) then I do not need any relays (I would not need the 100 amp relay or the standard 30/40 amp relay)?

9) rocker switches to fuse --> You have three rocker switches and from the looks of things you have all three rocker switches going to one fuse. --> If I have 6 accessories and 6 rocker switches wouldnt I want each rocker switch indivdually wired to its own fuse. Meaning I would have a power wire going from each rocker switch to the fuse. so if i had 6 rocker switches i would have 6 seperate wires going to 6 seperate fuses

Here's a setup with a winch as well.

Thanks guys. If you see any errors in my logic or drawings, please point them out and I will fix accordingly.

what fuse block did you use, i like the cover on it.
what gauge wire?
tks bob

Yeah that looks like basically the same thing. Just be aware that if you use the same fuse block I did it has a 100 amp limit.

When you say 100 amp limit help me understand how that works.

If I have 4 accessories hooked up (just throwing numbers out)

accessory 1 --> 20 amps
accessory 2 --> 30 amps
accessory 3 --> 60 amps
accessory 4 --> 100 amps

If I only have accessory 4 turned out the fuse box will send all 100 amps to accessory 4.
The only time I have to worry about the fuse box amp limit is if I wanted to power accessories 1,2,3,4 for a total of 210 amps beacuse the fuse box can only send out 100 amps?

If my logic is right, then there would be no need to ever want more than a 100 amp fuse box because surely noone would have every accessorie running at the same time. --> example you would have forward lights running while backup lights are running. the most you would have running is LEDs, stereo, forward lights..ect...surely thats not more than 100 amps.

I did not get the one with the negative bus. However, I kinda wish I did, but I think space may have been an issue if I did. I remedied not having the negative bus by using the bolts that hold down the coolant reservoir. I just ran a negative lead from the battery to it just to make sure I had a good ground.

I ran 8 gauge on mine and 4 gauge on the other that I did. I only used the 4 gauge because I had it lieing around. It was only 10' so 8 gauge was sufficient.

Anytime, let me know if you have anymore questions.

Huh I was gonna say, I used the dunertunes panel that gave me a total of 8, but I have a 900.
