OK.....the fuse is designed to melt above a certain current, so DO NOT put a larger fuse in it.........however if you own a testlight, put this in series, and it will light up......the reason is you have a 12v feed of course, but you also have a short to earth on the other pin...this should not be the case.......so out the testlight in series, and the lgith should be on ..then disconnect the radio wiring, and the light should go out..........

If it does, then the short is internal of the radio, and it must be replaced/repaired.

If it does not go out, and the testlight remains illuminated, then the cause is the wiring.....maybe a screw that has recetly gone though it, or something of that nature....

Let us know how you go !!

Put new marine stereo in boat when hooked up battery crossed wires with second battery and blew fuse, now keeps blowing same fuse


If you mean you put the two batteries in series and loaded the radio with 24 volts, you need a new radio. You will have melted components inside and are causing a dead short.

96 chevy truck, fuel pump relay switch (located under the hood, driver's side wheel well) keeps shorting out and melting fuse panel


I would replace the fuel pump and the fuel pump connector, both have problems in this year that cause excessive current draw and blow the fuse and overheat the system. If the relay socket terminals are discolored from heat that must be replaced as well. Of course before replacing any parts have a GM dealer confirm the problems i have guessed are to the cause.

92 grand marquis i have 1 wire and fuse that keeps gettin hot and the fuse keeps blowin. the wire has melted down into where it connects to the back of the fuse box. It get very, very hot at the connection...


you have a slow short in system this can cause a fire you need to determine what circuit it is and check for either a defective part also bad electrical connection you will need to possibly replace the wire or insulate it after cause is found

I keep melting fuses for my blower in my heater?


You have a serious electrical fault in your blower/heater. The fuse is protecting your wiring and prevents overheating/burnout.
Do not install a higher rating fuse as you can cause a fire.
You need to get an auto electrican to fix the short/fault.

2006 kia sedona a/c keeps blowing fuse


Not unless you are willing to risk electrical damage or a fire! A fuse is a protection device that is designed to blow if the amp load in a circuit exceeds the "safe" limit for that circuit. Fuses are built with a specific amp rating which is marked on the fuse. The wiring and design load of the circuit dictates the size of fuse that's required to protect the circuit. Circuits that draw a lot of power need fuses with high amp ratings (20 or 30 amps) while those that use minimal power require smaller fuses (5 to 15 amps).

When the current in a circuit exceeds the normal limit for whatever reason, the metal element in the fuse melts and opens the circuit stopping the flow of current. A short, for example, causes a runaway electrical current. If not stopped, wires can start to melt and things can catch on fire. So respect the amp ratings specified for fuses (which can usually be found in your vehicle owners manual, on the fuse block itself or a fuse block reference decal).

What happens if you install a fuse with the wrong amp rating? If you install a 20 amp fuse in a circuit designed for 10 amps, you're asking for trouble. A difference of 10 amps might not sound like much, but it may be enough to fry a sensitive electronic component or to overheat wires to the point where the insulation may start to melt.

WARNING: Under no circumstances should you ever bypass or eliminate a fuse. No electrical circuit should ever be operated without fuse protection. This is extremely dangerous, especially if you've had problems with a fuse blowing before.

If a fuse keeps blowing, it usually means something is amiss in the circuit. The wiring should be checked along with the components in the circuit to determine if there's a short or other problem.

The fuse for the windshield wiper circuit, for example, may blow if ice or debris builds up in the cowl areas and interferes with the movement of the wiper arms. If a fuse blows in a motor circuit (heater blower motor, cooling fan motor, power seat or window, electric fuel pump, etc.), it often indicates a shorted motor. If a fuse in a light circuit blows, look for wiring or connector shorts. Adding driving lights may also overtax the headlight circuit unless a separate circuit is provided for the driving lights. An A/C fuse will blow if the system is low on refrigerant and is working unusually hard, or if the compressor is hanging up. Stereo systems with high amp boosters should also have their own electrical circuit with fuse protection to avoid overloading the normal radio circuit.

Radio & clock keeps stopping


You have to find out what is causing the fuse to short out. The fuse saves your radio and clock from damage and you have to make sure that the wires to the radio are tight and do not have a hole in the wire insulation causing the wire to shoot electrical current to metal or another wire. I would ask the dealer did he find out what caused the fuse to blow before he put a new fuse in, when your car was in the shop. He has not finished working on your car.

Blown Fuse / Electrical problem??


you have a short circuit somewhere..possibly in radio itself. if fuse feeds all 3,unplug radio and see if fuse still blows..electrical problems can be time consuming

Tripping fuses


find what fuse is, You have to follow the wires with patience, from the fuse box to the item, you have a short circuit look if the horn + wire is not touching metal outside or inside the steering column, have You replaced the steering wheel? if the same fuse covers the dome light, take it a part and see if the + wire is touching the inside of the roof, plastic melted, or look at the on and off Dome switches at both doors, look for the positive wire on radio, antenna and main light switch, yo can disconnect every item and check any time hot wiring that fuse with copper wire every time, to You are sure
