- Q: My cousin gave me his old xbox but hes lost the cables so i asked one of my friends for his xbox cables to see if it still works and when i tried plugging it in the power wouldn't go in the xbox my cousin has is a halo 3 limited edition which is either an arcade or hes taken the hardrive and my question is, do all xbox-es have the same Cables for power etc and if not were can i get the right power cable for this console preferably bought in the uk
- No. Older versions of the 360 have a much more powerful brick. The newer ones have a less powerful one and the cable that goes from the brick to the plug is different.
- Q: Why is my 2 Gage power cable from the battery to my amp is to hot and makes a big spark and burns the wire when you meet one end to the other end?
- Too hot means the current is very high. Probably in excess of 200 amps. I suspect there is a short in the amp, specially if you tried to connect it hot and drew a spark. That will kill a lot of electronics. .
- Q: everything was working great! and then i blew the main fuse! i replaced it everything was fine after that but then out of nowhere i only have power in half of the power cable connected to the amp!! What can i do??
- I okorder /... Under the column for 90 degree cable in copper pick the wire gauge that is closest to your amp requirements without being under. For example: 1200 watt amp = 100 amps of power 2 gauge copper can handle 130 amps (This chart is missing 3 gauge which some places do carry, which can handle 110 amps) 4 gauge is only good for 95 amps. These ratings are about heat build up from inductance of the current. When the heat exceeds the rating, the sheathing melts and conductor degrades at it's weakest point. I recommend use of THHN electrical wire. It is gas and oil resistant and has heavy strands that hold up well to the stress of vehicle install situations. If your wire and fuses are properly sized, then check all of your connections. Often times heat and vibration will loosen screws on amplifier contacts. Also, under the hood, heat can melt your fuse holder causing plastic to coat the contact points (in which case you'll need a small file to clean the contacts) There's really a lot of possibilities here and your question is quite vague and convoluted. Please give more details or take some time and analyse the problem carefully. Chances are that you will discover the source of the problem in a matter of just 15 minutes or so of checking.
- Q: i'm having a power cable coming from the feeder pillar going to utility box that serving a yacht, i'm having few cut off in that cable what is the most good idea to repair it without replacing the cable and what is the material that used in that ?
- Have you got an anti surge socket to even out any voltage spike in line? I have and I've had several power cuts and my computer has never been affected. If not, then there is a possibility that you have blown the motherboard or the PSU. The reason this happens is your PSU drops the mains voltage from 240V to about 4.5V or less that your motherboard uses. Now when you get a power cut, when the switches in the power lines drop out, as the gap in the switch increases the voltage will jump as the current is trying to jump the gap. Thus for a few milliseconds the voltage in the mains can jump up to 20% which take it up to about 280V. Push that ratio all the way along and your motherboard voltage will jump to about 6V. Poof! Motherboard blown. Your only option is to put it into a workshop and find out exactly what damage you have done to it. You may be lucky as some manufacturers fit internal anti surge fuses.
- Q: What can I use for a power cable? Need a new one and I am not sure what to get. Could you send a link to one please?
- Looks OK for the price.
- Q: Whenever I unplug the power cable, the laptop starts to lag, bad, and yes I do have a fully charged battery. This has been happening ever since I got the thing, and no it has nothing to do with the battery, and no matter how many times I re-plug the cable and take it out again, or just leave it in, it continues to lag. The only time it stops is when I reboot, at least until I unplug it again. Also, it has nothing to do with the performance battery plan. Any ideas? This is really annoying.
- Do you mean lag as in a slow OS. Well- Where is your SPEEDSTEP set at in your BIOS? You may have 3 or 2 settings which ARE affected when your Cable Power is removed it will go to a Bit Slower Processor Speed to prolong the battery. If after you change the settings in BIOS and it does this again, its likely need to be sent back for repair under Warranty as this is NOT Normal...
- Q: What cable am I supposed to use for power?
- That kind, it's kind of hard to see on the OKorder pic. Usually your switch should come with a console cable and the power cord, unless you bought it used. The person probably kept it.
- Q: my Sony Bravia KDL32BX300 power cable has been partly chewed by a hamster, whats the best way to fix this, to cut off damaged wiring and replace the plug or do i need to replace the whole power cable?? thanks
- Change the cable and give the hamster away.
- Q: I currently have a 250 watt 2 channel power cord and a 500 watt alpine amp with 2 12 inch mtx terminator subs.i am continuously blowing blade fuses and i ended up buying a 680 watt power cable. Will this blow out my amp or do any damage or will it be all good and give the maximum power my amp can supply? (Without exploding) just wondering thanks!
- 250 watt power cord? Where are the fuses which are being blown? Maybe you put in the wrong fuses or the wrong amperage fuse.
- Q: i have a 97 chevy malibu and i need to know where to run the power cable through the fire wall. or where could i get a diagram that is simple enough for me to understand...
- Either find a rubber boot with enough space through it (where your steering column goes through), or drill a hole and use the grommet that comes with your Amp Install kit. If you choose to drill, MAKE SURE you have enough clearance on both sides.
