What would you like to do?
If an S10 truck will not start is there a relay or circuit breaker that could be the problem?
Well somethings i need to know?
Is the truck engine turning over and just not starting?
If the truck is turning over i would first off guess either gas or elelctrical problems.
If the starter is not turning the engine over, then i would point at the starter relay (you should hear that click when you turn the key). Also if you find that the relay is fine and it is just not clicking then i would look at the ignition switch on the steerin column.
Also, it may be the ignition control module. If the engine turns, but no spark, this could be the ptoblem also. Good Luck!

The circuit breaker obviously breaks the circuit but only in an attempt to stop a surge of electricity going through your house and possibly hurting you if you're using an app…liance, or popping light bulbs and most likely starting a fire.
"Fuse/relay center under the hood" I don't know about 95's, but in the 96 it's in the glove box. Yes, the 95's have the horn relay in the glove box.… It's the second relay from the left.
An Earth Relay Circuit Brearker(ERCB is a circuit breaker that senses an earth leak within the system and responds by cutting the power to the appliance or section or giving a…n alarm pending on the complexity of the system. Most of them can be set to a certain sensitivity, for homes it will be normally 30 mA fixed earth leakage current with an instantanous cut out. For industrial and commercial application the setting can vary pending on the protection needed.
The tripping mechanism for most high-voltage circuit breakers is released through the use of a solenoid built into the circuit breaker. The supply to the tripping solenoid is …from a DC source located in the substation building. There are various types of protection relay that will energise the tripping circuit -e.g. an overcurrent relay will detect a fault current due to, say, a short circuit in the protected line; after a specified time delay, a pair of contacts inside the relay will close, and energise the trip solenoid, opening the circuit breaker, and disconnecting the faulted line.
A relay senses a condition (voltage, flow, amperage, pressure, level, etc.) and allows component actuations (circuit breaker operation, pump start, valve open/close, etc.) to …occur. It is part of the control circuitry for a component. A circuit breaker interrupts electrical current flow by opening a circuit under load conditions. Both can provide component protection, but only a circuit breaker directly protects components. A relay could actuate a circuit breaker to provide protection.
A circuit breaker is a device for the limiting of current supplied to a circuit. Typically using a bi-metalic strip of metal to sense an increased current. The bi-metallic ele…ment will react to the increased current by heating up, and typically 'tripping' a mechanisim that will open or clear the circuit. When the bi-metallic unit cools of, the circuit breaker can usually be reset. After repeated 'trips', it is possible for the circuit breaker to become ineffective, wear out, and require replacement. A relay is an electro-mechanical device, typically used to control a system or application. Where as a electrical current is passed through a coil of wire, generating a magentic force which then effects a mechanical response. Such as opening or closing a contact that completes another electrical circuit. A circuit breaker is to designed to protect an electrical circuit, and a relay is designed to control one. Unless a relay has a circuit breaker included in the construction (very uncommon/extremely rare), it is no protection to an electrical circuit.
The anti-pumping relay is a device in circuit-breaker whose function is to prevent multiple breaker closures. For instance, if the operator gives the closing command to the br…eaker by pressing the close button and the breaker closes. However, a fault in the system causes the breaker to trip. Since the close command is still in the pressed condition, there is a chance of the breaker closing again and being tripped by the relay multiple times. This can damage the closing mechanism of the breaker. The anti-pumping relay prevents this by ensuring that the breaker closes only once for one close command from the control panel.
A circuit breaker is a overcurrent device. It prevents fire. An electrical circuit is only as strong as its weakest link. When the voltage rating of a device is exceeded, it… arcs. Current overloads are less obvious and easier to create. When the current rating of a device is overloaded, the device gets hot, eventually burning up. This can cause a fire. You want your breaker to be your weakest link, because it is designed to safely handle overcurrent situations. If your breaker is not the weakest link, wiring or a wiring device in your home will fail first, possibly setting your home on fire. Some things to remember: A breaker is a safety device. It is there to protect conductors and equipment.Only a Ground Fault Circuit Interrupter (GFCI) breaker will protect people from a shock or electrocution. If it pops, something is wrong. Chances are it is not the breaker! It is against the NEC to reset a breaker unless you know it was an overload condition. If it is a short-circuit, it must be fixed before resetting. Do not replace a breaker with a larger one. The circuit it is feeding cannot handle the extra current and will burn up before the new breaker trips.If a breaker trips frequently, chances are it is overloaded. Look into splitting the circuit it powers into multiple circuits on multiple breakers.If in doubt, call an electrician. Negligence is fatal with electricity.
What could be the problem if a Honda Accord EX will not start and the fuel relay switch keeps switching off but the switch not need replacing?
Answer You should first check to see if there is a good spark coming from the ignitor. Remove a spark plug from a cylinder, plug it back into the plug wire,… and place it near a good ground source that is NOT near anything flammable (i.e. fuel rails, injectors, the fuel filter, your battery, etc.). Turn the engine over and watch for a spark. If there is a nice blue spark the ignition is ok. If not, then replace all worn ignition components including the ignitor if necessary. Should you have good spark and still the car won't start you should make sure you have adequate fuel pressure. Have you changed that ten dollar fuel filter lately? now might be a good time to do that. To check for fuel pressure locate the fuel filter next to the battery. Disconnect the battery and cover it with adequate amounts of rags or other NON conductive material so it will stay dry when you remove the fuel filter. First loosen the banjo bolt on top of the filter hose while covering your wrench with a rag (*this releives fuel pressure AND lets you know that pressure exists*) then proceed to undo and replace the filter. Once complete you should haev to turn the car over a few times before it will start. Depressing the throttle while turning over can help speed this process. Did that do it? Well if you have fuel and spark and you STILL can't get your car to start then you might have bigger problems. A timing problem could be a cause. Honda timing belts "SHOULD" (i.e. you better do it!) be changed every 90k miles. If your timing belt has snapped you could be in trouble. It's worth the money to TAKE IT TO A DEALERSHIP when it comes to a timing belt. If your Honda has very high mileage you may have other problems amidst that require more in-depth technical diagnosis than a home user would likely be capable of, and even if they were capable an even smaller percentage would have the equipment to do so. A dealership will usually charge a half-hour to an hour of labor for a thorough diagnosis of the vehicle. Even if you choose not to get the repair done there you will at least know it's been diagnosed by someone with dedicated Honda experience and factory training.
It is provided to avoid if someone unconsiously or consiously presses the on push button provided on panel considering the fact that the breaker is intact/closed.
My 94 Chevrolet S10 will not start it makes a clicking sound when the key is turned from inside the cockpit. Is there a relay or fuse that could be the problem and not the starter or solenoid?
Bad connections . If the starter is clicking when you turn the key then the relay is not the problem, more likely is the battery and starter wire connections. Take them off… and clean them before putting them back on ( have the battery checked ) corrosion will cause the symptom you described, however there should be a starter relay in the engine compartment fuse panel.. ANSWER: . If the truck is a standard transmission, it could be the Neutral safety switch, which is located under the clutch pedal. However, most likely it is the solenoid on the starter, I just had the same problem, time for a new starter.
There are a few things that could be causing your S10 to not wantto start in cold weather. You should check your throttle positionsensor, coils or possibly a vacuum leak.
A circuit breaker in the off position should not be pushed to the on position until the problem is what?
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic funct…ion is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city. Types: MCB (Miniature Circuit Breaker)-rated current not more than 100 A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation. Breakers illustrated above are in this category. MCCB (Molded Case Circuit Breaker)-rated current up to 2500 A. Thermal or thermal-magnetic operation. Trip current may be adjustable in larger ratings. Fuses - These come in various sizes and make ups. The downside is most fuses need replacing after tripping.
1. Relay-"it is the sensing device which is connected to power circuit and if the any parameter of circuit crosses safe limits ,it sends signal to circuit breaker to break… circuit." 2. Circuit breaker-" A part of switchgear which is connected in circuit and it opens the circuit on receiving signal from relays"
A protective relay may fail to send a signal for many reasons - assuming it should have operated (so pickups, time dials, etc. are set so the relay should have operated), the …relay may be out of tolerance, if it is a microprocessor based relay it may be in some state of failure or there may be a fluke situation that causes an element to hang up, if it is solid state, it's power supply may have failed (many solid state did not have any sort of monitoring for this condition). Battery power may not be sufficient to operate the breaker, or wiring to the breaker may be compromised (open test switch, lifted wire, rodent damage to wiring, etc.). The analog connections to the relay may be bad, or wiring may have issues (such as multiple grounds on PT/CT connections). I've seen where a CT was supposed to be wye connected and one of the ground jumpers was missing, which caused some strange behavior. A relay output contact may have failed as well - if not properly designed, these can get burned out fairly easily. Microprocessor relays have an abundance of programming options; sometimes they get programmed wrong as well.
If you are trying to start a motor, the breaker may be sized improperly. The breaker should be rated at 250% of motor current. ( a 10 hp motor rated at 14 amps would require a… breaker of 35 amps. 250% X 14 = 35) If breaker is sized properly the motor may be overloaded or wired for the incorrect voltage.
