Regulators are supposed to turn off and on quickly. When the alternator drops slightly below a threshold voltage, the regulator turns on, causing the alternator voltage to go up. When the alternator goes above a threshold voltage, the regulator turns off causing th voltage to go down. The idea is that the alternator keeps the voltage between two set-points. If the regulator operates too slowly you will notice the flickering. It doesn't mean that anything is wrong, it's just annoying. Sometimes you can run an alternator load test and the problem will solve itself, but usually you'll just need to live with it. *************************************************** I have the same truck and I had the same problem! Try this: check your fuses. I think that you'll find that the "Alternator field" fuse (under the hood--see your owner's manual) has an issue. In my case, the fuse looked good, but my voltmeter showed that I had a voltage on only one side of the fuse (you can test a fuse without removing it by contacting each side through a small opening in the plastic with the 'positive' contact and a ground point with the 'negative' contact; remember that the engine should be running for this test). If you have the same problem as I did, the flickering will eventually worsen until the fuse connection finally fails completely and it will appear as though your alternator has failed. Fortunately, I discovered the problem before it discovered my credit card.
if you leave any lights on in the car you may cause you a flat battery. if you leave any lights on in the car you may cause you a flat battery.
Dead cell in the battery or the ignition or lights were left on.
water in the wiring or a low battery
A short in the wiring.
A loose battery cable can cause your vehicle to on most stall and it can cause the lights to Flickr. Make sure your battery cables are tight and free of corrosion.
If you have no battery then you have no power.
No. A bad battery is not causing your dash lights to go on and off. A different part is bad. Without equipment I have no idea what it is.
Do you mean What does it mean when the brake and battery lights come on in when it is already started? Check your alternator may be its not working well it cause the battery sign comes out.
It can, if you leave the lights or flashers on too long.
Yes that is all
Either too big or no fuse going to lights . Sometimes there is no fuse and the voltage is regulated through the battery . If this is the case and the battery is bad it will cause too much voltage to go to the lights .
Weak battery? Loose or corroded battery cables? Starter solenoid?
A dead cell in the battery will cause it to loose it's charge overnight. The only fix is to replace the battery. Also if something is on drawing power from the battery it will run it down overnight. Look at all lights. Interior, under hood, trunk, give box, brake lights, etc. It can also be a stuck relay.
Either your battery is dead, or your alternator has failed.
Turning Parking Lights ON while Charging BatteryNO, it serves no purpose other than to reduce the life of the parking light bulb filaments, and to cause the battery to have to be charged longer.
A Low battery could cause this - try getting a jump from someone,when it is cold the battery will, if they are low sometimes, not have the cranking power needed to turn over a cold engine. To test if your battery is low turn on your lights if the lights are dim then it is your battery.
A dead battery
Bad Battery. Bad Alternator. Lights left on by mistake. Something left running. Exc.
Not really. This sounds like a bad ground on the battery or the regulator.
bulb gone? fuse burned? battery dead?
It could, if the lights are on all the time.
The most common cause for your 1997 Honda Civic lights to dim is a bad alternator. The alternator is not charging the battery. The battery retains a small charge, but not enough charge to run the engine.
If there is power lost, lights that dim and a battery light that comes on there is most likely a connection that is loose somewhere. It would be best to check the alternator or battery cables.
Alternator has/is going bad.
