Had trouble starting car put key in turned twice but nothing lights lit up?

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)

Please explain the charging circuit in automobile. 1. How does the charging light comes on when ignition switch is turned on 2. How charging light comes on when alternator is not or less charging?

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.

Why does the battery and parking brake light stay on dim when the car is turned off?

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.

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.


What does the red battery light mean when it comes on when i turn on the ignition?

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.

How do you repair a 99 Aurora inside light staying illuminated while driving but turning off 8-10 minutes after shutting the ignition off Is there a problem with the twilight sentinel switch?

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.
