However, things are different now and current day appliances are power hungry.

The types of electrical equipment and appliances used at that point of time were vastly different from the ones used today and their power requirements weren’t as demanding. They can be purchased from any car parts shop or hardware store.Electrical wiring and systems that were installed up until a decade ago were quite different from the ones used today and there was a specific reason for this.

They only cost a few cents and it is a good thing to know how to do. Inspect each fuse visually, and replace as necessary. Some fuses are designed to come out by hand, while others require a pair of tweezers or a smaller pair of needle-nose pliers. Most newer cars allow removal of the fuse box lid by hand or with a flat head screwdriver. The location of the box and the assigned circuit for each fuse should appear in a diagram in the manual. To see if a fuse has blown, the first step is to consult the owner’s manual.

A wet harness can corrode over time causing an eventual short circuit and many blown fuses. If you a leak that is soaking your carpets it could cause a wet wiring harness. Any connector that gets exposed to the elements could cause a short circuit.As the wire moves it may only occasionally come in contact with a surface that will cause a short and a blown fuse.

This is often the cause of intermittent shorts. This exposed wire can cause a short when it touches a ground surface.

Friction against a wiring harness has caused the wire insulation to fray.

This overloads the circuit causing a short and a blown fuse. If a wiper motor or power lock solenoid have fried and melted on the inside, it might start drawing too much power in an attempt to keep working. The three causes from the most common to the least common are: Each one has tell-tale signs we look for during our investigation. There are three main causes of a short circuit. Fuses protect both the wiring and the devices in the vehicle.Ī short circuit is simply a low resistance connection between the two conductors supplying electrical power to any circuit. They can only handle so much power before catastrophic failure and possibly a dangerous fire occur. Electric devices also have these same limitations. The amount and type of conductor used in a wire determines how much power it can handle before it overheats and melts. Each wire in a car has a specific gauge or thickness. The number embossed on the fuse, such as 5, 10 or 15, indicates how many amps may be pulled through the fuse before it blows. The more devices there are on one circuit, the heavier the amp load.Įach electric device, including headlights and radios, pulls a certain amount of amps from the electrical system. Check what devices or lights are on that circuit, as it may be the case that a new amplifier pulls too much power, causing the fuse to blow.

The vehicle’s manual should contain a diagram with this information. Be sure to check, first, that the fuse has the correct amperage rating for the circuit it is in. Let’s start with something simple and obvious. The fuse is the incorrect amperage rating There are a few reasons why you might continually blow the same fuse. You will know is you blow fuse because any of the components on that circuit will stop working, like the radio, the interior lights, or the electric side mirrors. These fuses are safety devices consisting of a strip of wire that melts and breaks an electric circuit if that current exceeds a safe level. Every vehicle has a fuse box somewhere in the cabin, usually underneath the steering column near your feet or hidden within the glove box.
