Headlights are flickering with car running on buick-lesarbe

Sometimes, a headlight may start flickering due to physical damage to headlight components. The inside of the connector may start to melt, causing a poor connection. the bulbs or lamps of your headlights are old or damaged, it can cause the headlights to flicker. Fortunately, this can be a relatively quick fix.

When the alternator starts to give out, your car’s electrical output is affected. This could result in flickering, dimming, or inoperative headlights, as the headlights depend on power from the vehicle's battery. When the alternator is unable to charge the battery, the vehicle's electrical system will quickly drain the battery. One of the most common causes of headlight flickering is a dying battery. Your headlights rely on power from the battery to function properly. If the battery is failing, flickering, or dimming headlights may be the result. In this situation.

Get a volt meter, start your car and see how many volts your car is producing while running. Should be around 14 volts. May want to watch the meter for a while since your electric seems to fluctuate. Most voltage regulators are internal of your alternator. If you are getting a lot more or less than 14 volts while running, replace the alternator. If it is not charging, voltage will drop as vehicle runs, until battery is dead.

the headlights Flicker could be caused by the alternator. Local auto parts stores will test this vehicle charging system with their mobile analyzer and it will determine the problem...
The alternator generates direct current for recharging the battery and for powering vehicle electrical loads.

Traction light is on because the abs is on.Traction control needs to have the abs system fully functioning to work.Most common cause of abs light is a wheel speed sensor.As for your lights flickering the alternator may be going out or you have a poor ground connection.Would check battery cables first to make sure they are tight.

bad fuse panel.or loose main wire in fuse panel

Go to Autozone or Oreillys for a free scan of both the computer and the alternator. It sounds like a Regulator is bad. There reason it works well the first 10 minutes is that the battery is recharging and the Alternator is steadily charging via the Regulator. Then when the battery is charged the Regulator is tapering the charge and providing just the amount of energy your car needs.

This provides an off-on cycle which is the flicker you notice. It is not normal to show up and should be seamless. You may have the type of Alternator with a built-in Regulator and will have to open the Alternator or replace it to change the Regulator. There may also be a Headlight relay they mentioned, but if you notice the flickering in the overhead Dome light with the engine running at different speeds it is more likely the Regulator.

bad ground at battery or chase.

Flickering headlights can be caused by a bad alternator, the car might not be charging correctly the battery, check alternator. Good luck
