Short in the running lights and the dash when you start it how do i fix it?
"Blowing" FusesWithout seeing and trouble shooting your vehicle no one can tell you where a short is in an electrical circuit. The key to this repair is to find/identify the short. Fuses and Circuit Breakers are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating which can result in damage to the conductors, and worse, the possibility of a FIRE which could destroy the vehicle. When a fuse, and replacement fuses, repeatedly blow, is an indicator of an UNSAFE CONDITION in that circuit, usually a short. Do not install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would invite damage to the wiring and an electrical system fire. The proper "fix" is for a qualified technician, who knows what he/she's doing, to troubleshoot the circuit, find and identify the defect [in this case a short], and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse].
What is An example of a short circuit?
A short circuit is one that is characterized by extremely low resistance. This will result in the extremely dramatic increase of current. High current will flow until a safety device opens the circuit, or the weakest link in it burns out. And one of the two usually occurs in a moment or two.==Short Circuit happens when the cables of the electrical appliances are worn out or it's not connected properly,a short circuit may occure.A short circuit has a very low resistance that almost all electric current flow through it.It'll affect the operation of the electrical appliances.Owing to the heating effect,the excess electric current would produce a large amount of heat,wihout a fuse or a circuit breaker,a fire may be occured when there's a short circuit.
What will happen to the transformer if the rated voltage is applied to the winding during short circuit test?
the winding would burn....
What is the role of a switch?
A switch is installed in a circuit to stop the current flow. Without the switch there is no way to disconnect the operation of the circuit's load. In modern households the switch is a convenient way to control room lighting from a convenient location. Without switches the circuit power would have to be controlled from the service distribution panel's breakers. In this scenario the breaker would be in the same class as a switch.
Why does wiring have rubber around it?
The rubber is insulation; it is to keep the wire from coming in contact with another wire, or grounded equipment, which would result in a short circuit.
What type of circuit would be used in lighting circuit?
A lighting circuit would be a parallel circuit.
Which would be better in lighting a house a closed or an open circuit?
Which would be better in lighting a house a closed or an open circuit ?\
Why would you have power to your tail lights when switch is of?
it shows that somewhere on the tail lighting circuit there is some kind of a short circuit,one can test using a multimeter to find the probklem..
Is a megohm a short circuit?
No. A short circuit would be zero ohms.
Why would a computer wire melt?
Short in the circuit or the circuit was overloaded.
What type of switch would be used to control a lighting load from one control point?
In this type of situation, where there is more than one lighting circuit, a lighting contactor would be used. These types of contactors can be obtained in four and five pole configurations. Make sure that the contactor is rated for lighting loads and not motor loads. A normal switch, single pole single throw, would be used to switch the contactors on and off. A single switch could then be used to control as many contactors as you need to operate the lighting circuits.If there is just one lighting circuit, the total circuit amperage must be known, then the switch would be sized to the amperage of the circuit.
Why does a energy efficient bulb not complete a circuit?
There is no element to heat to complete the circuit. Another example would be magnetic induction lighting.
Can you explain house wiring using electrical symbols and identify two simple circuits within a home?
Electrical symbols are used on electrical prints to show the location of devices that the architect would like located at specific spots. Two simple circuits in house wiring would be a receptacle circuit and a lighting circuit.
Will 7 amps overload a household lighting circuit?
Lighting circuits (UK) are fused at 15A. If in doubt, check the fuse/MCB. Unless the 7A device is lighting, connecting it would be illegal in the UK. Don't forget anything else on the same circuit.
Do Transformers bathe?
no. they would short circuit.
Will you cause damage connecting ac current to a dc circuit?
It depends on the circuit. For example, providing the a.c. voltage is the same as the rated d.c. voltage, it would not harm a lighting circuit.
What would cause 80 amp alt fuse to keep blowing?
Short in the wiring, fuse too small for the circuit, circuit overloaded, or short in something plugged into the circuit.
