Q:What component/s were damaged if a power supply unit switch to 110 and run it on 220 V?
If this is a desktop power supply as laptop supplies should be auto-detecting/switching, it would probably be cheaper and less hassle to just replace the supply being that you can pick one up for $20-$60 average depending on brand/wattage. Switching power supplies can be a pain to work on and then trying to find those hard-to-find transistors is no fun
Q:How to figure wire size needed for 12v DC?
You need to size the wire for the maximum current it could carry. If it is directly off the battery and going to a block that is fused for a total of 120 Amps, then you have to assume that the wire could be asked to carry 120 amps before a fuse would blow. According to your chart, that would be a 8 AWG wire (150A for 10 feet). First problem is that 8 * 30A 240A. If you did 8 branch circuits all fused at 30 with no fuse between the block and the battery, you could exceed the rating of the block! The safe way to do this is to add up all the loads you plan to put on this wire, right size the fuses to those loads and then size the wire for that total plus about 10%. You could also put a single fuse right at the battery that would be sightly larger than the total max load current.
Q:My windshield wiper fluid won't stop spraying?
so your spray isnt working change the fluids
Q:What is wrong with my stereo?
the speaker wires may be corroded,too long,or shorted when pos neg are inserted into speaker wire clips,the net needs to allow a refined search so one can find the device itself,maybe the patent prohibits repair people from showing pics schematics,can you post/upload a pic of the thing? one of front,rear,speakers,and aux components?
Q:88 300ZX, why did my stereo, pwr mirrors, pwr mirrors defog switch and my intermittent wiper lose power?
the cable on the niv side of the batt is croted or not makeing concate with the batt
Q:Odd occurrence with component cable?
What you describe is unusual, but not unheard of. It's called EMI (ElectroMagnetic Interference), or alternatively, depending on the frequency involved, RFI (Radio Frequency Interference). First, if your ceiling fan had a short circuit, it would blow the fuse or circuit breaker (if not, you do have real trouble), but, regardless, it would not operate. So your fan does NOT have a short circuit, and you are not about to burn down your house - relax. See here for all the interesting details about the sorts of things, man-made and natural, that can cause weird things to happen with electricity:
Q:Why did the digital display instrument cluster go dark in my 1991 Cadillac Brougham?
Replace fuses When water comes in contact with a electrical component bad things can happen.
Q:Charging problems on a 96 Beretta Z26 3.1 v6?
Go to a wrecking yard and get a fuse box cover. You can also test your system yourself for a short or parasitic draw. First, shut off all the car's lights and accessories then close all the doors. With the battery in the car, first remove the negative battery terminal. Now, using a multimeter set to the DC volts scale put one probe on the negative terminal of the battery and the other probe to ground. Read the meter. If you read more than about a quarter of a volt, you have a draw somewhere. Troubleshoot the draw by having someone remove fuses one at a time until you see the meter voltage drop. When you see the voltage drop, you’ve found the circuit in which you have a power drain. Thoroughly examine that circuit, area by area, until you locate the reason for the voltage drop. Isolate and repair the problem. If this doesn't fix the problem, take extra care for a few days and see that all the lights are off before you walk away from the car for the evening. It could be something so simple as a door that hasn't closed fully, causing an interior light to remain on overnight or maybe a bad switch on an under hood or trunk light. Any of those are more than enough to do the job. I've done it myself, more than once. Usually, a full battery charge will take care of it. Even a jump start and running the car for an hour or so should build your battery up enough to get you going again as long as your alternator is doing its job.
Q:I need to find a how to basic level to rewire a sail boat it has a 4 fuse panel?
any of the books by Nigel Calder will give you the details on proper marine wiring. I suspect your boat was made in the 1970's or 80's and the wiring is not adequate for today's safety standards. The number of fuses depends on the accessories you have. And you want to be sure to fuse each major accessory e.g. bilge on one, radio on one, navigation lights on one,
Q:I have a sanyo 25 inch tv that makes a buzzing sound after being on for a few minutes then gets louder. Why?
For sure please call Sanyo service center to help you (don't wait until the set blow the worst case it can set fire. Buzzing sound usually comes from the component that has coil in it, like flyback, transformer. But it usually comes from the flyback when its leaking. If this the safety fuse you're talking about, when it blows your set won't be able to turn on anymore.
