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.: Unhook the battery ground cable and hook up a voltmeter between the cable and battery. Start pulling fuses until the meter drops below 11 volts. This will tell you which circuit is drawing power. Check out all items on this fuse. The most common places to look are the lights in the trunk, glove box and under the hood.

Q: I have a 24vac about 5 amp transformer that will have leads coming out of it for testing electric circuits. I need to know if there is a component to help me out. If the leads were to touch together it would short out frying my transformer. I need a device that will upon the leads touching will not allow the current to back into the transformer causing a short. I know a fuse accomplishes this but I don't want to keep buying/replacing fuses since they will touch a lot! I'm going to use a resettable circuit breaker for know till I see if there is a better alternative. Thanks!: Model railway transformers, before they got all electronic, used to use a resettable electro-mechanical circuit breaker to cut out if there was overcurrent. So apart from a complex electronic current limiting circuit, a breaker will do the job for you.

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: How do I know when its time to change my transmission fluid on my 2009 elantra?: For a healthy auto transmission system, change the ATF fluid including the strainer assembly every 40,000 km. This will preclude wear and tear of the internal subassemblies.

Q: How can I tell if the fuse is blown?: 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.

Q: I have the right fuse the cord is ok the capacitors appear to be ok I don't see anything that stands out to let me know where the problem is. I change the fuse and as soon as I plug it in it blows.: This answer isn't going to be very helpful, but it is the best one I can give without being there in person to snoop, meter and prod things a bit. You likely have some component in the power supply section that has gone out of tolerance by shorting quietly. This occurs when a resistance drops enough to blow fuses rapidly, but the very fact that it blows fuses rapidly keeps it from ever damaging anything to the point of finding the problem with a visual inspection. My best guess from here is that this model VCR / DVD has quiescent state power so that it can be used with a remote control at all times. That leads me to believe that the problem itself would be in either the particular section of the power supply that provides this power or in the sections dealing with the remote sensor and any micro controller that interprets and activates those commands. There is one fairly simple possibility you might have overlooked. Make sure that no connectors or bare wires are against the case that you can see. Also check for minor discolorations of the boards due to heating. If you aren't a qualified tech or a talented hobbyist with tools available such as a multimeter, this will be very difficult for you to track and repair yourself I'm afraid. And, as always, it isn't safe to work around equipment you're not thoroughly familiar with, even disconnected. Best advice is take it in for repairs or replace it. Sorry I can't be of more help.

Q: I was told to replace the distributor and check the fuses. Also to check the wiring from the distributor to the alrenator. Where is all this stuff at and how do I check it The car just stopped and sounds like it is going to start but won't. Thanks: Probably under the dash on the left side of the steering wheel. Most internal items have fuses there. Some radios have an inline fuse, especially if it is an after market radio, but you would have to remove it to find it.

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 have a Kenmore 110.64672400 and my husband thought it would be easy to disconnect the buzzer. He cut the two wires to the buzzer and started the dryer. It ran - until it started tried to buzz - then it died.What did we fry? What do we now need to replace?Please help.: go okorder
