It can keep the car, or some accessory in the car from running, depending where the break is.
The negative wire is grounded.AnswerThe negative wire is grounded.
Most likely the wire to the light is frayed or broken and touches the body of the car, thus creating a short. The body of the car is the 'negative earth' and the live wire is connected to the plus pole of the battery. If the insulation is broken the wire touches earth and thus the fuse blows. Another possibility is wrong wattage or voltage of the light bulbs, although that is most likely not the case here. The light switch could also be faulty. Just go over the system and the wires until you find where the positive wire touches earth. Is there a problem with the lights themselves? Are they correctly assembled? Check that too.
it should because car is running off alternator and if you do this it will not charge battery back up
It is an electrical output wire. Connect white to the positive of a device and the negative on the device to ground. Only works then motor is running
No, the vehicle chassis becomes the negative while the single wire running to the light is the only power needed. The other half of the circuit just ties to the body of the vehicle.
On the car battery, the positive wire is red and the negative wire is black. If the body of the car is metal or conducts electricity, then the body of the car serves as the negative wire. The metal in the engine serves as the negative wire.
The positive speaker wire is a solid color, your negative wire should have a stripe on it.
The 1999 Jeep Cherokee ignition coil used a black wire for the negative wire. The negative wire should be on the left post.
Sounds like there is an overload in a wire and it is blowing the fuses to keep from doing more serious damage. Have the wires to that fuse traced and tested to see if the wire is bad or if the ground wire is loose.
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
yes
Run the yello wire of your new radio to a constant power wire (usually orange). A good one is the orange wire running to your cigarette lighter.
