    So do you just use two leads? one from the battery and one to the amp/inverter? What im trying to say, as by looking at that picture, it looks like it splices 2 leads together, with a fuse in the middle, am I correct on this?

    They are called "in-line" fuses. Therefore they go inline. Imagine a hot wire going from your device to the battery. Cut it. You now have to loose ends. They attach to each end of the in-line fuse. Direction doesnt matter. You still have to ground the device. Do not connect the grond and the hot together via the inline fuse. That will result in a blown fuse. I recomend this for you.

    I think we should try to get these available at the mp3car.com store. They are very useful training tools. They are made for kids but believe me, we could all learn something from them.

    You know whats sad, I went to school for all of this (graduate and certified PC tech, we took AC/DC, transistors, Analog, Digital, all that). I kinda skipped past all of that crap, since I was there just to get my certifications (Cisco, A+, etc)

    I am a full time computer tech, I watch over 25 servers, but don't know about all of this...sad isnt it?
    2000 Sunfire build 100%, or is it ever really 100%?

    Now all of that crap is coming back to haunt you. A friend of mine went to TESST Electronics school, made honor roll every quarter, aced all of his tests. But ask him about basic parallel resistor networks or the function of a capacitor and he has to go back to his notebooks to look it up. Funny, he too is a systems administrator monitoring a company's servers and WAN. I wonder if that's coincidence or a pattern?

    I'd have mentioned that, but I thought it was obvious. Then again, the original poster was asking what a fuse was... Maybe not so obvious.

    I think those kits are a bit too in-depth for what the original post was about. A simple "a fuse is almost exactly like the circuit breaker in your house" kind of answer would have sufficed (as would a search...)

    True, but way overkill. I seriously doubt that anyone on this board would buy one, because we all either
    1. (mostly) know what we're doing already, or
    2. find it easier to start a topic titled, "What is electricity, and do I need it for my carputer?"

    Its a pattern. When someone learns a fact without understanding the reasoning behind it, then other facts relating to said fact can be a mystery.

    Would one expect an electrician to know anything about R/C circuits? Or an "IT professional" (read: retarded computer monkey) to know how to write a piece of software? Sure, the occasional overachiever might, but in general, no, one wouldn't.

    All of the A+ and Cisco and (insert flavour of the week here) certifications (MS in particular) are bunk - get yourself a CS or EE degree if you want to know what you're doing. Everything else is just a gold star for paying too much for what amounts to freely available information.

    I'm not sure about this info as I'm a total noob and have yet to actually get my project finished and installed, but I read somewhere that you should place the fuse as close to the battery as possible, no more than 18" from the battery.

    I'm currently CCNP & CCDP, we don't see "parallel resistor networks or the function of a capacitor" as a network admin . That should be done at the A+ course.

    But the point is he went to a school specifically to learn those things.

    And CavityCr33p even said:

    You can't climb the ladder of knowledge, forgetting the rungs that you were previously on.
