    well i have some questions...(i never used a multimeter)
    i ll get a multimeter soon but i want to know how to use it

    i found a guide here

    http://www.consoleworkshop.co.uk/Tutorials/GC laser tweak.php

    1. do I have to turn on the gamecube to check the laser with the multimeter

    2.do i turn the laser with bare hands ?

    3.how are the risk of briking the cube ?

    4.anychance of tweaking without multimeter ? (juste turning a litte ^^)

    thanks

    1. No. Potentiometers are variable resistors, and there should be no power in the circuit while measuring Ohms. Could result in false readings, possible damage to circuitry, etc.

    2. No, a small screwdriver should be used.

    3. Depends on your level of skill. I'd assume yours is little to none, so chances are low to mid depending on how cautious you are and whether or not you follow proper procedure. Unless of course, you completely misadjust the pot and severely shorten your laser diode's lifespan.

    4. No, since there isn't a standard setting. Also, considering this is your first time trying, you shouldn't even risk it.

    And use the guide on modthatcube since it's a bit more in-depth than that is.

    still 2 small question...

    1. they said to turn it anti-clockwise

    but what happens if i lowered the pot to much and i want do add some ohms ?

    do i have to turn it clockwise or is that forbidden ?

    2. do i have to turn that white thing or that mini-blackbox
    using one or 2 minis screwdrivers ? (isnt really clear on the pics)

    1. Yeah, counter-clockwise will decrease it, so naturally, clockwise will increase it.

    2. Basically, it's kinda like a small black box with a little shiny screw on top of it that you have to turn. If you try turning the box, you could very well tear it off the board. You just need a small screwdriver like the ones used to repair eye glasses. If you don't have one, just find a paper clip and flatten the end with a hammer.

    Usually, more power has to be delivered to the laser in order for it read recordable media. Sometimes though, no change is necessary, as there are quite a few people on this board that didn't have to make any adjustments.

    I, on the other hand, have had to replace my laser (played GC too much lawl) and adjust the pot accordingly. Keep in mind, that I'm basically the minority on this one since not too many people burn out the laser diode strictly from use.

    my multimeter doesnt have an lcd display, its a meter. and it doesnt have the proper settings. on modthatcube it said to turn it to 2000, mine only has: 1x, 2x, 5x, 10x, 50x, 1kx settings. can i adjust it with any of these because i dont want to buy a new one.

    when i installed ships for people i never adjusted the pot.

    You can use an analog meter if you know how to read resistances with it.

    What's the default scale? I can't tell you what to set it to unless I know what it is.

    the default scale is 1x, it also has a dial used to adjust ohms readings( up for lower ohms, down for higher). the dial looks like one you would see as a volume cotrol on a cd player. i have no idae what this does.

    What I mean is how much resistance can 1x measure?

    The idea is, to select the lowest scale capable of reading <500 ohms accurately.

    i dont know, i have to use the dial to raise the ohms. its weird cause when i set it to any of the settings its at 0 until i adjust the dial. the dial raises and lowers the ammount of ohms.

    Do you have a digital camera that you can use? Cause I still have no idea what to tell you.

    i dont have one. its just like a normal analoge one just without the 2000 settign or the other one that was listed on modthatcube. it looks exactly that same as the one on modthatcube but its 30 years old. still works for my dad though, and he doesnt know how to adjust the pot at all.

    Well, just go buy a digital multimeter for $5 at a hardware or electronics store. Without seeing it, I can't tell you how to use it...

    I got mine at Harbor Freight for about $4 and a clamp on ammeter for $11.

    Just search around and see what you can find.

    i have a picture of a multimeter that looks closest to mine. my analogue one has 1x,10x,1xk settings, not the ones in the picture.
    http://www.vehicle-wiring-products.co.uk/VWPweb2000/meters/photo/287621.jpg

    the way i adjusted my pot was by raising the ohms adjust. meter to max and set it to 1x setting. when i measured it i got 425, then reduced it to 178. is this right?
    the meter that is shown is diff. than mine. my meter goes up in 100 ohms incriments. then has 1k,2k, and 8k after it reaches 500. remember that this is the meter were i can see the ammount of ohms.

    it looks like:
    8k...2k...1k...500...400...300..200...100...50...10...0

    Ah, so you figured out how to use it.

    178 ohms should be fine as long as it can play back-ups.
