- Q: Cannot find a path to send the power cable for the amplifier through
- The firewall is the bulkhead between the Passenger compartment and the engine bay. Look for a rubber grommet in the firewall/bulkhead that has existing wires going through it and use this. Some firewalls have grommets that you can use to pass your power cable through from the battery. Remember to put an in line fuse on th live cable of the correct rating.

- Q: I have a Parrot Boombox bluetooth speaker but am missing the power cable. Can you look at this picture and tell me what kind it is and where I might get one?
- That's just a standard AC power cord. You may already have one around the house. If you can't find one, go to your local computer store.
- Q: if we provide power through power cable will there be need of extra capacitor near load?
- Yes, if you are talking about a bypass capacitor. Electronics always requires a bypass capacitor near the circuit/IC. Having one at the end of a cable means the cable inductance is in series, and the impedance seen by the IC power supply leads is inductive and high instead of the needed low impedance that a local bypass cap provides.
- Q: So I had this monitor I used to use, then didn't use it for a while, now I want to use it again but can't find the power supply cable. I can get a new one, but the thing is I have to know what to ask for, right? I don't know what cable to ask for. I did some google search on it too but still can't seem to find exactly the type of the cable that is specified. Help? Can someone do it for me so I can go to my local electronics score and look for a cable that will do the work?

- Q: If you submerss the metal end of any kind of power cable like an extension cord in water will it work again?
- It will if dried out over night. Placing it in direct sunlight will dry it faster. A hand held hair blower/dryer will work the best. Never use a wet cord for anything! This could lead to electric shock and/or death!
- Q: 1) How is the connectivity between 2# of 300AH battery and 200A Power plant made?2) Need to know the cable sizing between battery and power plant.3)calclation to arrive at the sizing of input cables, output cables and charging cables between battery and power plant4) Are charging and discharging paths same in the batttery? ie when load is on battery whether the load current flows through the same cable of charging ?5)A photograph of the system will make me understand the solution better
- The battery and power plant statistics do not enter into the calculations. I assume that the load is continuous, and the battery is to be continuously trickle charged. The power plant will have to deliver the load current and battery trickle charging current, at the voltage necessary to charge the battery. You will need to know the load current, the trickle charge current, the distance between the power supply and the battery (or load if you connect directly to it), and the voltage necessary to supply the load and trickle charge the battery. The voltage drop will be the total current multiplied by the total circuit resistance. this resistance will be the sum of the individual conductor resistances. As an equation, this is Voltage drop = total resistance times current in amperes. The total resistance will be the voltage drop divided by the current. Now you know how much resistance you can stand. The National Electrical Code in the US has tables showing the resistances of various sizes of wire, and how much current they are rated to carry. From these, or maybe from you wire supplier, you can find out what size wire you need. It will need to be large enough to supply the voltage and current, and have a rating for at least that much current.
- Q: im curious what a good rule of thumb would be for determining how strong a fuse to put in line to the amp. im getting a 2300 watt amp but dont know how many amps of fusing it uses. so i dont know its power draw. any help would be great
- HM. that alot of wattage i would try 2 100w fuses
- Q: I got a free graphics card from my cousin and my computer only has the SATA slots for graphic cards and the one he gave me has the 4 Pin cable. Is there anyway to get it converted or any cables that can go from 4 Pin to sata? I wanna see how this graphics card goes when its working fully.
- Sure you don't have any molex connectors at all? Not even in your DVD drive? If so, get a Y adapter with a good amount of length. If not, then look for an adapter. Be careful as the vast majority are to convert a molex power cable to a SATA power connector, not the other way around. In the worst case you could hook up a separate power supply to it.
- Q: Hello,We are having a problem with our power cable and that being that most time whenever we insert the power cable into the back of the laptop the orange light at the front of the laptop does not always light up. We think the problem lays with the power cable, because it has been tugged and dropped before on many occasion.So, is it possible to buy a power cable for our Toshiba laptop, and we have retained the sticker. We think that the Toshiba part no is PA3396E-1ACA and the model no is PA-1650-02.So is it possible to buy a new power cable?
- It is possible that your cable may have some broken wires inside that are causing your problem, or it may be the board as mentioned above. The board that is being referenced is the power connector inside your laptop and it's connection to the system board. What can happen is the electrical connections (solder joints) from the connector to the board become broken/loose and you have an intermittent connection. I have re-soldered these for friends when theirs go bad, otherwise a replacement system board would be required. I have also seen where the small leaf spring contact inside the connector becomes flattened and has poor contact as well (if this is the type of connector you have). You could check this with a good light and look inside the hole, there should be a center pin contact and a leaf contact along one side that should come down about halfway into the hole to the pin. To test where the problem is, connect your cord to your laptop, now hold the connection very still at the connector and wiggle, twist, push, and bend the cable at various points to see if the light at the front of the computer goes on or off. Now also test the plug at the computer by carefully moving it up, down, around in various ways to see if the light goes on or off. Wherever you find your problem is where you'll need to fix. If it is the power cable, yes, you should be able to buy a replacement. Try Toshiba's website or google the numbers you have to see what turns up. Hope that helps explain things better. Best of luck.
