  • Straight 12V?

    I'm trying to wire the solenoids and everything right now. I'm using this diagram to wire it up.
    http://www.go-fast.org/z28/photos/nitrous/n2o-wire.gif
    And I was wondering. Can the solenoids just take straight 12V power from the battery withour any fuses? Or do I need to fuse the power so it wont blow something up in the solenoid? If I do need fuses, what amp do I need?

    FUSE EVERYTHING ELECTRICAL!!! Closer the fuse to the power supply (in this case, the battery) the safer it is (less wire to fry).

    Last thing you want is an electrical fire destroying your car.

      Alright. So.. What amp fuse would I need to use?
      How many amp does the solenoids need to work?

        You sure I need a fuse? I have been looking at more Nitrous wiring diagrams and all the diagrams shows power going to the relay straight from the battery.
        Like this one..

          &lt;----- not electrically smart :(

          The fuse reply makes sense

            Hmm.. I cant find an answer for this on the internet. I've looked at several install guides and I dont see anything about fuses mentioned in it. But I'm too afraid to just wire it up and fry my solenoids. If someone can see if theres any fuse between the relay and the 12v power, it will be helpful.

              Your best bet is to contact the manufacturer for advice on what amp fuse to use.

              Being a Certified Electronic Technician, I advice EVERY circuit to be fused (as close to the power supply as possible)! The last thing you want is a solenoid or hot (12V) wire to short to ground, sending tens to hundreds of amps flowing through a wire designed to only carry a few amps. If you don't have a fuse, your wire becomes the fuse. Wires catch fire, fuses don't! ;)

              I'm sure you've seen burnt up cars along the side of the Interstate. IT COULD HAPPEN! PROTECT YOURSELF AND YOUR PROPERTY! :cool: [img]graemlins/thumbsup.gif[/img]

                With over 500 amps flowing out of the average battery, a fuse is not enough. Wire a relay into the circuit! A relay will take that large source, and make it a smaller, steady, usable source that will not fry your wiring or solenoids. a 30 amp relay can be found at any radio shack or parts store. Most of them come with a diagram explaining which wire goes to what. Post for more info.

                  Current takes the path of least resistance. The law of electricity won't allow that much current to flow to your N2O circuits unless there's a direct short. A relay does not protect circuits from shorts... only helps to carry larger current loads. It's still a direct path to the power source! Without a fused power wire, there's still a chance a wire and/or relay can catch on fire during a direct short.

                  If you were to take a wire and short the positive and negative terminals of the battery, you'd see what I was talking about (fire) cause the wire would become a permanent part of your body! :eek:
                  Take the same wire with a fuse in line and short the terminals of the battery.... see the pretty flash of the fuse? It did it's job and you still have use of your hands and heart! ;)

                  I don't recommend doing this at home, kiddies, but I hope my example explains things a little more clearly! :cool:

                  Total misconception and not true! Send 500 amps through a relay and you'll see fireworks! ;) It's nothing more than a thin copper band with copper contacts that is moved with electromagnetic energy.

                    Alright. So, I'm gonna go and get some 30amp fuse at autozone tommorow. Thanks for the help all! ;)

                      Jason I totally concur with all of what you said, it's what I study in school. So are you saying you do not run our nitrous system (if you have one) with both a realy and a fuse? I of course do run both, and most any electrical componant you purchase has instructions for wiring a relay into the circuit also. I have seen guys who ran only a fuse on their kits and could not make a good run all the way down the track because they always popped the fuse.

                        I don't use nitrous but I've done many wiring jobs in cars, houses, and circuit boards. Nitrous or not, the law of electricity is the same.

                        Relays are nothing but switches. Relays, in the case of nitrous systems, are used to switch the solenoids off and on. The relays you are referring to are usually 30 amp relays. The reason relays are used is because most of the automotive grade switches are not capable of carrying the amount of current the solenoids require. The relay is triggered by a low current (1/4 amp is usually sufficient) 12 volt source and this is what normally runs through the interior switch. Both the main power wire for the solenoids and the power wire for the relay should be fused. See my example: http://www.wtfba.org/temp/fuses.jpg

                        If a switch is not capable of handling the current needed for an application, a relay is used in addition to the switch.

                        <blockquote>quote:</font><hr>I have seen guys who ran only a fuse on their kits and could not make a good run all the way down the track because they always popped the fuse. <hr></blockquote>

                        One of two problems here.... 1) They're not using the correct amperage fuse (too low) or 2) somethings wrong with their wiring. Most likely answer is #1. You must know what your circuit requirements are before fusing it. You don't want to use a fuse that is too low or too high. If your solenoids require 9 amps to operate, you'll want to use a 10 amp fuse. Use a 5 amp or even a 8 amp fuse and it'll pop. Use a 15 or 20 amp fuse and sure your solenoids will work but if ever there was a problem, it would require that much more current to blow the fuse. By the time the 15 amp fuse popped, your solenoids done welded themselves closed do to the extreme heat from the excessive current.

                        Ya'll see where I'm going with this? Contact the manufacturer of your solenoids, find out the electrical requirements, and use the proper fuses in the locations specified in my example.

                        Fuses are like airbags.... they pop to protect the circuit (person) in the case of a terrible accident (short circuit). Don't confuse fuses with relays.
