You probably have an alternator going bad. Have it checked on or off the vehicle at a local Auto Zone. Good Luck!!!
If you have a voltmeter, measure the voltage across the battery, with the engine running. It should measure around 13 -15 volt (alternator is ok) now turn the engine off it should measure 12volt. If you do not have a voltmeter ,let a friend watch your headlights at night with engine running,than turn engine off, your headlights should go dimmer with engine off.
Sometimes, brand new batteries need to be charged for a while before they have the power to engage the solenoid/starter properly. The battery may have enough jucie to light up the headlights and run the stereo, but not to crank the engine.
the battery is a part of the vehicle as is the engine.
Turn on your headlights and try to sart the engine. If the lights go out the battery is probably bad. The contacts on the starter solonoid don't cause it to click.
Sounds like a very weak battery.
Dim headlights, Flickering headlights, Starter sounds sluggish when cranking, Battery light comes on or flickers, Voltmeter drops below 13 volts with engine running,
no, using your headlights during the day, just uses power from the battery, and not from the engine, the battery is constantly being recharged , while the engine is running, any way,
its in the engine carpartment beside the battery
Yes, but there may not be enough power to start the engine.
Alternator
It sounds like there could be an issue with the alternator or the electrical system in your car. The drop in idle speed and juddering indicate a potential problem with the engine. The flickering interior lights and headlights suggest an issue with the alternator not properly charging the battery. It's best to have a mechanic inspect and diagnose the specific cause to address the problem correctly.
Because the power for your headlights is pulled from your battery. When the dashboard lights dim after turning on the headlights the dashboard lights aren't getting as much power as they were with the headlights off. With the motor running or off? The headlights draw a lot of current, but should not visibly affect other systems. There could be a problem with a worn out battery, an alternator that isn't charging correctly, or you have a bad earth between the battery and the chassis. Check the large cable connection between the battery (usually negative these days) and the bodywork, or between the engine block and the bodywork.
Could you be more specific? Is the battery dead, will the engine not turn over, are the headlights not working, etc.?
First check you battery. Use a volt meter must have more than 12.2 volts, if under 12 volts, charge or change battery. No volt meter, then turn on your headlights, if good, then check shifter, in park and in neutral. If no headlights, charge battery.
It is in a small black box screwed to the side of the engine bay between the battery and the light
Leaving something on (like headlights) for an extended amount of time without the engine running will shorten the life span of the battery unless the battery is the deep cycle type. Overcharging an automotive battery will also shorten its life span.
In most cars the battery is in front of the engine. In some cars, it is beneath the truck sometimes with the spare tire.
