Q: I was wondering if anybody could tell me how to find a short circuit in my car because it is draining my battery. The car has all electrical components brand new such as the alternator, starter, battery, voltage regulator and relay. The car is not blowing any fuses but drains the battery overnight. Can anybody tell me how to test for a short circuit? Thanks to everybody that helps.
start pulling 1 fuse at a time out of the fuse box and then take your neg. battery terminal off and then just touch it to the battery post and see if you get a spark, keep doing this with all the fuses until you find the fuse that when it's out you don't get a spark from the battery terminal and then you will know what circuit that is drawing your battery down.
Q: I have a 07 civic coupe. i need to know what components i need in order to connect 2 subs to an amp to the stock stereo and where i can find them. any info will truly appreciated, thanks!
a car stereo place would be best
Q: I have a (optimus stereo amplifier mpa 250) Every time I turn it on the fuse blows, I have it connected with the right stuff so I am not over ridding it. I disconnected everything from the amp and it still blows the fuse every time I turn it on. Not sure if I miss connected something when I dis-wired it again. Please guide me with this issue, I've been threw Two fuse bags and can't afford to go threw more. Should I get it checked by a professional or what? Please help out someone. Thanks.
That fuse collection is saving your amp. You've got a short circuit in it somewhere. Needs checking out. Take the cover off and look for burn marks in the mains-in part and on the circuit boards. You might have a burnt-out resister or capacitor somewhere or a badly screwed up transister especially in the output stage. Power transisters can get hot. They have heat sinks they get bolted to and heat paste to make a good junction so the heat gets transfered better, Check the wires all round for molten or burnt insulation. Sometimes it's just dust that builds up inside that causes the problem especially in vintage amps that may have running twenty years without a clean out. Sometimes it's insects that get burned to a cinder and form a carbon bridge between components. Carbon is a good conductor and then you get a short circuit. Make sure the plug is out of the wall socket and give the amp a brush out with a vacuum cleaner nozzle held close to the brush. A 1-2 inch house painting brush works fine.
Q: I have a video mixer here which the power plug says 12v 300mA and i have a power supply which is 12v 1700mA. Will i be able to use this power supply or will it blow the video mixer up? Thanks
You can use the power supply. The key is, it provides the correct voltage. The mixer will pull the amount of current that it needs. The power supply must have a equal or higher current rating than the mixer pulls.
Q: I unplugged an air freshner from my lighter. Immediatly after I noticed my lighter, dome light, power antenna, rear defrost, key in ignition chime and the lights at the bottom of the doors didn't work anymore. I switched all fuses in fuse box with new ones and the same components still didn't work. Any suggestions would be greatly appreciated!
A Fuse it that simple one fuse power many thing it only cost like a dollar to but and 1 min to change so good luck
Q: I am trying to keep my battery from dying overnight since i need a new door jamb switch b/c my interior lights will not go off.
Two ways to solve the problem: Locate remove the fuse However that fuse is most likely to provide power to other components so not such a good idea. OR Pop the switch out of the door frame remove the negative wire from the switch. (usually black ) Wrap some electical tape around the terminal on the end of the wire put the switch back in place. Problem solved!!!
Q: I have 5mm LEDs that Im using to make automotive tail lights with and I need to know what I use for surge protection.
No surge protection is required, and as for fusing, use a normal-blow fuse rated about 20% higher than the current normally drawn by the lights.
Q: I have a rotel RB-850 that won't turn on after working fine forever. Power light does not come on. Someone suggested it might be a blown fuse.
I repair these - it is never just the fuse! I urge you to not attempt to just replace the fuse. Fuses do not go out due to age, they blow to protect other components from further damage and/or fire (no, I am not kidding). The amplifier requires service by a qualified technician. There are no user replaceable parts inside. Those Rotels were good units and worth the repair. Your best bet will be a stereo/home theater store that does repairs, although you may find a TV repair shop that has an tech that knows vintage audio. Now put that screw-driver away before you hurt yourself.
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
Q: I have already checked the fuse and it is fine. If I bought some freon would that maybe get my air back on? If not, any ideas on what else could be be the problem?
Fan motor could be effected by a fruse/relay. If you have this working but still no cold air then you need to recharge your system.
