Can it be these possible solutions: I have a low battery, or a low alternator output, or excessive belt tension, or a faulty headlamp switch.

Battery has zero to do when the car is running. the entire electrical load is on the alternator. If lights are dimming with the car running, your alternator would be the first suspect. second would be that your idle is not fast enough to satisfy the electrical load. As for the belt tension, I'd say that a loose belt would be more of a problem than one that's too tight.

it's the alternator
the alternator regenerates the battery, since the alternator is not working properly it drains the battery.
you can have the alternator checked, some places would say the once you replace the alternator they would recommend that you buy a new battery,
Don't buy a new battery until after you replace the alternator and have the car running for about 1/2 hour to regenerate the battery.
I'm sure that you would Not need to buy a new battery.
I hope this helps.

Most likely you problem is cause by a slowing the engine idle of your car. What year is your car. Newer cars require a computer adjustment to idle the car up older cars will have an adjustment near the carburetor or throttle body. It should idle between 750 to 900 rpm at idle depending on the number of cylinders. Try to idle the car up a bit. If that's not it it could be any of the things you mentioned. You are on the right track.

the skill help on the brakes isn't operating because your idle is too low to provide a vacuum. in the adventure that your vehicle runs nice at speed, i'd suspect an ignition problem. Is your battery and spark plugs sturdy? simplest element to do is administered a diagnostic, write down the codes and put up them on right here, someone can inform you whats incorrect. Chugging exhibits misfiring to me, if this does no longer take position at the same time as throttle is utilized, your timing is off- examine your timing, then see the way it runs with the help of the total rpm decision.

All of the above except the switch. You may not even have a problem as at idle with your lights on you are not getting as much "power" to the lights till you rev up. The normal idle voltage on a full charged battery with your lights on should be around 13 to 13.5 volts and about 13.8 with them off.

If they only dim when the car is idle is it probably your alternator taking a crap on you. if anything with the belts you have one that is too loose. I would say to have the alternator checked out and see where it goes from there.

Maybe your battery cables just need to be cleaned. If so just pour a coke on them (it has to be coke brand though, not coke in general). Check and tighten the connection to your battery and cables.
Also it could be your alternator output, but check for corrosion on the battery terminals before you leap that far.

I would replace the battery, perhaps you have a lot of accesories in your car such as an amp and other random stereo whatever and you need a battery that can handle a larger load.

in my past experiences, when lights dim only at an idle, then it can be only one thing...a faulty alternator

take the cables off the battery and clean them with sandpaper this should fix it but if itdont have the charging system checked at murrays or auto zone
