Q: I put an aftermarket radio in a 2002 pt cruiser and at first all was good until I noticed a fuzzy ness to the radio stations so I messed with the antenna cord and all of a sudden the radio wouldnt power on at all. The fuses seem to be all good. All lights on dashboard work. It also says no fuse on the dash. Everything works but the radio and I think the power locks.: Check fuse #18 (20amp, yellow) in the Power Distribution Center box under the hood. This fuse has a plastic pull-tab on it. It's used to control Ignition-Off Draw IOD. The fuse is pushed in when you take delivery of the vehicle. The owners' manual explains that it's used to keep the battery from draining during extended storage. If it's blown, you will need to determine what caused it to blow. This 20a fuse won't blow unless you've added a load to the circuit or there is a component failure. It doesn't take much to blow the fuse, the addition of a stereo or alarm, or even the power window modification, if you wired it into that circuit. If you haven't added an additional load, and the vehicle self-tests check out OK, dealer service will need to diagnose the problem.Also check the fuses in the fuse box by the driver's left knee inside the car and a 40 amp fuse up in the power distribution box under the hood.

Q: I check the fuses and they are good.: Geez this seems to be occurring to an excellent sort of persons i understand - we could continuously all go decrease back to roll up domicile windows. My Taurus had that issue and that i took it in 4 diverse situations earlier it ultimately worked perfect!!! I have not have been given any thought what they ultimately did to it, i understand I asked that they replace the completed door.

Q: I wrote to the company and they said they can't (or won't) identify the thermal fuse rating, nor will they tell me where to get one. They told me to just buy a new fryer for $50. I don't want to do that, being that I know the fuse costs $2 (I just replaced on my coffee machine). The numbers on the old one are illegible. If I knew the specific rating, I think I could just scoot down to the local Radio Shack and get a new one, like I did for the coffee maker. I can find no service manual anywhere. I assume the rating has to be at least 450 degrees F, but I want to get some more info before replacing what is essentially a fail-safe protection device. If I get on that is rated to high, I run the risk of severely overheating the unit, and I have teenagers who may use it; too low, and it will blow before the oil gets nearly hot enough to fry my chicken. I know I can make the thing operate without the fuse, but I would like to replace it. Any info?: okorder

Q: I just picked up my 1996 Jeep Cherokee from the shop. My mechanic fixed the ignition and a couple of other things, but now the power windows, blinkers, A/C and heat won't work. I checked the fuses, but they all appear to be fine. I'm gonna contact the guy tomorrow, but I just thought someone might have some insight. Thanks.: vfdsdfv

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!: You want an incandescent light bulb. Two 12V 60W car headlamps in series will do. If there is a short as such on the leads, the lamps will take the current and convert it to light and heat. The light bulbs will seem like a short circuit or low vaue resistor to low current loads. I have made myself such an arrangement to test 120V devices for dead shorts, which is a dual receptacle box, with the receptacles in series. I plug the device under test in one receptacle, a dual socket lamp in the other, fitted with a 60W and 40W incandescent bulb. I can select 40, 60, or 100W series load with that.

Q: I have a AEG Airsoft gun and It does not have a fuse on it.What will a fuse do to it and what should I expect it to do to the Airsoft gun's performance?Does the motor size determine anything?: Thanks for the question, we're glad to help out. Everyone gave pretty good answers to this one. The fuse is there for protection of the motor and electrical components of the gun. If there is a problem it will burn out before any other electrical parts do. If your gun doesn't have one, you probably don't need to worry too much. Most manufacturer's will only install a fuse if they think that the end user will be upgrading the battery, motor, etc. Entry level AEG's usually don't have a fuse because most users keep the gun as is and will get an intermediate or higher end model when it's time to upgrade. Also, the motor size will determine how well the gun performs and the rate of fire. I hope this helps.

Q: Hey everyone.I have a modest stereo set-up in my car and I am suddenly having problems with a fuse blowing. I have an Alpine head unit, Kenwood amp, and a single 10 Alpine sub. I have had this set up in this car for about a year and a half, and had the same set up in another car for three years before that and never had any problems. Now for the past week, the fuse in the wire running from my battery to my amp keeps blowing. When I replace it, it is good for about 30 seconds, and then it blows. Any advice on where to start troubleshooting?: Start by disconnecting the wire from the amp. Replace the fuse and see if it blows. If it does, there is a short in that wire. Look for somewhere where the wire has rubbed against metal, like where it goes through or around the firewall! If that is not the problem, re-attach the amp power with the amp off! See if the fuse blows! If it doesn't, turn on the amp. What you want to do is continue testing components until you find the problem!

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: 2.8 manual trans blows ecm b fuse in the under dash fuse box. Changed relays(2), fuel pump and ecm. It might be the fuel pump primer but I don't know where it is located.When I bypass the relay the fuel pump runs but when I try to start the engine while it's bypassed the bypass wire from the positive battery post gets red hot. The engine used to start while wired in this fashion when the fuse would fail. Now the fuse fails all the time.: You have a direct short in the ECM B circuit. When you bypass the fuse you destroy the harness, fuses are to protect the harness and the components they are connected to. They protect the ECM. The B circuit usually is the power circuit for the fuel pump, through the relay. Check the harness for continuity from the relay connector to ground from the fuel pump power supply wire I think it's tan/wht. If there is you have a short and you will need to pinpoint where. but you have probably already melted the harness together. Good luck. It might have been cheaper to hire a professional mechanic shop.

Q: I am replacing it in a UPS back up energy for my computer.please if you dont know dont answer, dont guess.: yes you can, 1 amp wont hurt it at all. just do it in a static free area.
