Hey, I am hooking up my amp which worked in my last car to my new one Miata MX5 and my 25 A fuse keeps burning out when I connect the ground wire to ground on the car battery.

I tried finding some place to ground the wire to my car frame prior to connecting to the battery but cannot find anything that works as ground. Any ideas? Jan 4, 9, 1, Your amp is likely broken, it has nothing to do with the grounding method.

Either that or there is a short in one of the outputs.Welcome to the ClassicBroncos. To take advantage of all the forum features please take a moment to register.

I'm at my wits end and I ran out of fuses so I had to give up I have a set of two relays for my headlights, one for high and one for lo beam. They are wired identically. They are grounded identically.

Yet one blows the fuse everytime. They worked great for about 8 months and it just started last week. Could the relay have gone bad? That was my next trial, but i'm out of fuses so it will have to wait til tomorrow Run a check on the wires.

Look them over good and make sure a power wire is not grounding out somewhere. Could have a chafed wire. A power wire grounding out on the body would cause a fuse to blow instantly.

It sounds as if it could be the relay. When they go bad the lights normally will just not come on though. It could also be the switch. The relay power is normally not fused it is the supply to to load that is fused.

Are you blowing the headlight fuse? Look at the headlight wires. Disconnect each head light see what happens. What was the last thing you did before this happened?

The relay supply is a fused 30 amp line. I'm not blowing the 'headlight' fuse per se, it is the fuse on the load going to the relay. The last thing before this happened was drive it normally, then it was parked for about 2 weeks. I guess I will start by trying one of my other relays and see if it blows up I've pulled each plug at the lights, still hi, but lo blows.

OK, I'll take a stab at it.

Not knowing exactly what you have for headlight relays I'll be guessing and using a few assumptions. But it should be generally good. There are probably 2 matching curcits. The original wiring is probably turning the relays on. I am guessing that the relays click on correctly for both low and high beams.

The fuses are between the battery and the relays. So the curcit that is blowing the fuse is simply Battery-fuse-relay-low beams. The fuse lives until the relay clicks in.You hear a pop and all the power goes out.

Everyone says, "Probably a blown fuse," but what does that even mean and what causes it? Find out here. Most people probably have experienced a blown fuse at one time or another.

My Amp keeps blowing fuses when the ground wire is connected.

Someone always knows what to do when this happens. Blown fuses are a common occurrence. Most people nowadays have had the old-fashioned fuse panels also known as fuse boxes in their homes replaced by modern electrical panels with circuit breakers—if the fuse boxes were even still there when they purchased their houses. You might be wondering, then, how to tell if a fuse is blown—an actual fuse, that is.

You will see that the fuse has melted, and there might be charring on the panel.

A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated. The destroyed fuse must then be replaced with a new one. Circuit breakers, on the other hand, have internal switches that are tripped by electrical surges to temporarily disable a given circuit.

A short circuit is a type of electrical fault. Faults, in general, occur when an electrical current strays beyond its intended path circuit due to a lack of resistance e. The result is a weak connection between the two conductors supplying electrical power to the circuit. Overloaded wires will overflow and cause damage.

A short circuit might even cause the electrical device responsible for it to be destroyed. Short circuits are typically stopped by circuit breakers, though, hence their name. First, test the circuit. Then check for any damage on or around the electrical panel. If you see any damage, call an electrician before doing anything else with it. If there is none, flip the breaker switch back to its operating position. If it trips again, though, call an electrician.

A ground fault is a specific type of short circuit in which the unintentional pathway of the straying electrical current flows directly to the earth ground or touches a grounded part of the system such as a grounding wire or the electric box. The danger of shock increases when a person is in direct contact with the weak path to the ground.

Be sure and test all affected system components and electrical devices. Call an electrician if something is still amiss.

How To Fix A Car That Keeps Blowing Fuses

Arc faults result from problems with wiring and terminal connections—for example, a loose terminal screw. If your home has AFCIs, the fault should have tripped the circuit. If it does not have AFCIs, then check for damage and call an electrician if necessary.

Was the breaker tripped? In other words, is one of the switches on the panel flipped? If so, the circuit breakers are doing what they were meant to do: cutting off the flow of electricity because of some type of surge fault or other problem. If the breaker trips again, there could be a problem. Monitor it and if it keeps tripping, call an electrician to check. Fuses come in many shapes, sizes, and configurations.Short circuits range from direct shorts that blow the fuse immediately, to high-resistance types that take several minutes to blow the fuse, to "phantom loads" that never blow the fuse, but can drain your RV batteries within a few days.

Although a volt electrical short circuit in your RV can be elusive, a systematic approach to finding and eliminating possible trouble spots, one at a time, puts this repair within reach of the typical RV owner. Attach the male spade AWG disconnects to the ends of the buzzer wire leads, so that you can plug the buzzer into the fuse socket.

Insert the male spade AWG disconnects into the fuse sockets and listen for the buzzer. If you are using a piezo buzzer and hear no sound, reverse the polarity of the wires and you should hear the buzzer.

Instabot examples

Leave the buzzer on; this will let you know when you find the short. Identify all the appliances and lights that this circuit powers, and disconnect them one by one.

If the buzzer turns off, then you have found the appliance that has the short circuit in it. Remove the male spade AWG disconnects from the fuse plug, and plug in a new fuse. Identify the appliances this circuit powers. Make sure all the appliances are turned off. Check the amp rating of each appliance, and write it down on a piece of paper. Turn on the first appliance, and check the ammeter to see how many amps it's using. Check the appliance's amp rating list to see if it's close to the listed amount.

Continue checking each appliance. If you see one that draws more amps than it's rated for, you have found the appliance that is slowly blowing the fuse.

This will show you how much current amps the RV is draining from your battery. Remove fuses. To isolate which circuit is causing the slow electrical leak, remove each fuse, one at a time, while checking the ammeter.

When you see the ammeter reading decrease, or go down to zero milliamps, note which fuse caused this.Discussion in ' Skid Steers ' started by ebenMay 10, Log in or Sign up. Heavy Equipment Forums. Thank you for visiting HeavyEquipmentForums.

Most of today's homes now use circuit breakers to offer this control and protection to individual circuits, but older homes that have not had their electrical systems upgraded may use fuses. The circuit breakers or fuses are normally found in a central main service panel.

Circuit breakers are lever-operated devices with ON-OFFs witches, while fuses are glass and ceramic cylinders with screw-in sockets. You likely already know where your main service panel is located and whether your system uses circuit breakers or fuses.

And you probably also know that when all the lights and fixtures in a portion of the house go dark or dead at the same time, it's because one of those circuit breakers has "tripped" or one of those fuses as blown. These devices are designed to automatically shut off power to the circuit when problems occur. In the case of circuit breakers, the immediate answer is to find the breaker that has tripped and reset the lever to the ON position.

When a fuse blows, a metal filament inside the fuse has burned through, meaning that you'll need to replace the fuse with a new one. But in most cases, the breaker or fuse is just doing its job when it pops.

An overloaded circuit is the most common reason for a circuit breaker tripping. It occurs when a circuit is attempting to draw a greater electrical load than it is intended to carry. When too many appliances or light fixtures are operating at the same time, the internal sensing mechanism in the circuit breaker heats up, and the breaker "trips," usually by means of a spring-loaded component within the breaker.

This breaks the continuous pathway of the breaker and renders the circuit inactive. The circuit remains dead until the breaker lever is reset to the ON position, which also re-arms the internal spring mechanism. The circuit breaker or fuse is sized to match the load-carrying capacity of the wires in that circuit. Hence, the breaker or fuse is intended to trip or blow before the circuit wires can heat to a dangerous level. When a circuit breaker regularly trips or a fuse repeatedly blows, it is a sign that you are making excessive demands on the circuit and need to move some appliances and devices to other circuits.

Or, it may indicate that your house has too few circuits and is in need of a service upgrade. A short circuit is a more serious reason for a breaker tripping. A "hard short" is caused when the hot wire black touches a neutral wire white.

In terms of the physics involved, a short circuit allows for a sudden unimpeded flow of electricity due to lowered resistance, and this sudden increase in current flow within the breaker causes the tripping mechanism to activate. But sometimes a short circuit occurs not because of the circuit wiring at all, but because of a wiring problem in an appliance or device plugged into an outlet along the circuit. Short circuits, therefore, can be a bit difficult to diagnose and fix and may call for the help of a professional electrician.

The presence of a short circuit can be indicated when a circuit breaker trips again instantly after you reset it. A particular type of short circuit, a " ground-fault ," occurs if a hot wire comes in contact with a ground wire or a metal wall box or touches wood framing members. Ground faults can be especially dangerous when they occur in areas with high levels of moisture, such as kitchens or bathrooms, or in outdoor locations.

A ground fault carries a definite risk of shock.And your mug can come in handy in hotels that provide plastic or Styrofoam cups in the room instead of real glasses.

More importantly, we can avoid all waste by opting for reusable hankies. Some people make their own out of old t-shirts and cloth diapers.

I found lots of hankies at a thrift shop. Another ingenious idea is the HankyBook, which makes carrying a cloth hanky so much neater.
