You have a flat battery.
The voltage reg is sticking and will run down the battery.
Check the battery. Turn headlights on - they will come on with or without the key if it has power from the battery. If lights do not come on, the battery is dead (try jump-starting) or there is a bad connection (loose cable), or a short in the electrical system. If headlights come on, but dashboard lights do not light up - check the ignition (cylinder / switch)
sounds like a bad light switch.
I had this problem on my disco 1. Turned out to be the alternator, which was replaced and the problem was fixed.
Never unhook the battery with the ignition turned on. There is always a little voltage spike that occurs when disconnecting or reconnecting the battery. If the ignition is on the computer will be powered up and that spike could "fry" the computer.
bulb no good.
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
Ever watched a movie called christine? Nah, check your wiring harness for the headlights and look for a bare spot(s) with wire showing...could be grounding
The light beam would leave the front of them at the speed of light.
The headlights place a larger load on the battery and cause the voltage to drop enough to dim other devices slightly.
Your headlights would come on and the light would speed ahead of the car at 186,282 miles per second.
Battery first. Will it start with a jump? Battery ok, then use a test light & see if you have current in the hot wire to solenoid when key turned. If you do, it's the starter. If not maybe the switch but start there.
If it's like a 1996 tracker the headlights won't come on unless the parking brake is released or the light switch is on.
The tail light fuse controls the headlights in a Nissan Altima. A second fuse box is located next to the battery.
Perhaps you turned on the interior lights when you were adjusting the headlights?
It's possible that you have a bad ignition switch. Normally, those lights won't turn on unless the ignition is turned to the "Run" position. A bad switch may be allowing current to flow through one or more contacts when it's not supposed to.
If you turn up your interior dashboard light settings, then the radio display will be brighter too. The radio dims to the setting for the dashboard when the lights are turned on.
The reason for no ignition light could be a low battery. The wiring system may be another reason for this. Check the white wires in the ignition switch and the multi-plug connector to ensure they are connected.
That light is a warning light for the battery charging circuit. In order for you to know that the light is not burned out, your vehicle manufacturer installed a test circuit which turns the light on when the ignition switch is turned on when the engine is not running, and turns it off when the vehicle starts and the engine is running, and the alternator is creating more electricity than the vehicle's circuits is using. If there should be a failure of the alternator, or it's circuit, or the output is below the current being used by the vehicles circuits, then the red warning light should come on. If there is adequate electrical output from the alternator it should stay off, EXCEPT for the bulb/circuit "proof test" when the ignition key is turned on while the engine is NOT running.j3h.
i would have the light switch checked to see if it is faulty
A car battery causes the headlights to shine
it means that either your keys are still in the ignition after you turned the car off, or your headlights are on, or you need to shut the door or trunk for it to stop blinking but wont ever go off
Check the door switches first. Then make sure the light isn't turned on either at the bulb or at the dashboard switch. Many vehicles eventually turn off the dome light, even if it's turned on by the driver, to save the battery.Note: If the door switch contact failed, it would fail in an "open" state, and the light would not come on when the door opened. If the door switch was jumpered (bypassed), or the plunger on the switch is not making contact with the door, the light would stay on when the ignition is on and then time out after the ignition is turned off. But, The most common mistake is to accidentally leave the headlight switch in the manual dome mode (having the knob fully rotated to the left, or, counterclockwise), then the light stays on while driving and will time out after the ignition is turned off to prevent the battery from running fully down.
