Q:i plugged my m-box to my mixer heard a pop and no more subwoofer lol. im trying to figured out what got burst ? fuse? somebody help please

Disconnect the sub from its power source. If there is a way to open it and check for fuses or other protective parts inside, try that. If you can't figure out how to open it or there are no fuses or reset buttons, take it to a repair shop. In the future, connect or disconnect audio cables only when all components are off.

Q:i have built a 1amp 7.2volt power supply and i'm wondering if it will be able to charge a 7.2volt 1600mAh battery.please help me, please, please.Thanks In Advance.

Not a good idea. You may blow a breaker or fuse, or the wiring and components could get so hot that they could start a fire. That wouldn't be very likely with only 7.2 volts, but still not a chance I would be willing to take.

Q:Battery is Good, Alternator is good, both have been tested. My car starts up with no problem. when im driving in a neighborhood without having to apply alot of pressure on the gas everything is fine. But the moment i enter a freeway/highway where i have to press the gas a little harder my alternator fuse (30a) blows instantly as soons i begin to speed up the battery light comes on. I put another fuse in and same thing, everything is fine when im not pressing the gas hard but the moment i have to apply pressure my alternator fuse blows and the Battery comes on. So replcaed the fuse once again. This time i put some tape around my O2 Sensor wires. And wala! It worked, no fuse blowing when i speed up but then after like 15 min of driving it started back :/. What could be a possible fix?? thanks!!

Alternator Fuse Keeps Blowing

Q:I installed my brand new battery in backwards, it was late at night and i couldn't see what i connected. When the terminals connected, a green wire connected to the starter popped in smoke. I took my truck to a mechanic and they said i fried my computer and that i needed a new one.or a used one. IS this seriously what i didbecause this is a $500.00 F*** Up.

You can certainly take your truck to a second mechanic for another opinion, but yes, that is what can happen if you hook the battery up backwards. It tends to fry electronics. Don't be surprised if once the new compute is hooked up, there is more damage to other components. And, yes, 500 bucks is actually fairly cheap for a new main computer for the car. Do it yourself, when you aren't careful, can be a lot more expensive than paying a professional to do it in the first place.

Q:i forgot to switch to 230v when plugging in my american desktop infrance, there was a pop, and now it wont start. did i completely breakit or is there a circuit breaker or something i can fix

chances are, you just overloaded the power supply. I would take it to a service center or a PC repair place and have them check it out for you.

Q:Both the windows and the interior light all quit simultaniously any ideas

check your fuses pull out the owners manual(in glove box if you have it). check under fuse identification check to see if they are running of the same fuse the book will let you know what components run off each fuse.

Q:I was trying to connect two power supplies together so that I could have a positive and a negative voltage. I mis wired and now one of the power supplies went out and doesn't turn on anymore. What are some possible problems? I'm guessing that it's just a fuse that went out.

What does connecting two together have to do with positive/negative voltage?

Q:I have a component cable with an end for a ps3, xbox 360 and wii. If I plug a xbox 360 and ps3 into it and then plug it into my tv will something bad happen if I have both my xbox and ps3 on? Or will this even work at all.

Not sure if you can connect them both. The adapter piece is probably too short to connect both. The power adapters will create too wide of a separation to connect them. If you did manage to connect them you're either going to get nothing or you're going to blow up your house and every house within a 5 mile radius.

Q:Blown Kenwood KDC-P5028 CD Reciever?I have a Kenwood KDC-MP5028 CD player. I was installing the system and everything was going fine. The wiring harness has the yellow cable missing which I think the the 12v. I attatched a wire and hooked it all up and everything was working fine. When I pushed the unit into the dash the wire cameout and it touched the black ground wire. I heard a pop and noticed that the unit was smoking a little bit. Now my unit will not power back on. The fuse is still good so thats not the problem. The radio fuse is also intact. Does anyone know what the problem is? Is there an internal fuse I dont know about? Your help wil be much appreciated. Im also trying to avoid taking it to a repair shop because I know they are going to charge me an arm and a leg. Thanks, Johnnie

rutrn to where you bought it tell them its defective

Q:I checked the cooling fan fuse underneath the hood but it is fine, i think that is for the radiator.There is 20 fuses in the hood fuse box. In the interior fuse box there is 25 fuses but my owners manual does not state any mention of an a/c fuse. What # is it?Where is the fuse for the air conditioner?2002 honda civic sedan.

both fuse boxes will have a/c components, and not just fuses. there are also relays
