Either the belt is slipping or the alternator is losing juice at a lower rpm....i take it it was checked in park,or taken out and tested by a machine which spins fast?

Battery light is on when idleing, but when i accelerate battery light goes out


Two things can make the bat light come on at idle but go off above idle.
The belt could be slipping because it is not tight, or glazed, or the alternator could be defective.
Once the engine starts, the alternator should be making enough current to "turn the light off". The light is grounded thru the alternator until it is charging, which reverses that circuit and kills the ground source for the light.
If you are sure the belt is ok, I would have the alternator bench tested, because usually if the belt is slipping it slips more at higher speeds.

I have a 2004 Ford Escape XLT with a V6. . and the battery light flickers under acceleration. The battery and connection were testted and both were ok.


Hello, If you have not put on a Serpetine belt in some time, then your belt has probably stretched to the point where it does not grip the pulleys good. You can also have a weak Tensioner pulley as well.

You need to replace both the belt and the Tensioner pulley to keep the Alternator pulley tight so nothing loses its, grip. Sometimes you will not hear a squeal from the belt, and the dash light will flicker.

Battery light comes on when accelerating, alternator is ok


In fact the Alternator is on it's way out, I had Taurus that was doing the same thing. When the RPM's were over 3000 the light would flicker. What happens is, the slip rings wear and get out of round and when the RPM's get too high the brushes start to bounce causing the light to flicker. Keep in mind the alternator is spinning about 3 times the speed of the engine. Pick up an alternator it's just a matter of time, mine went about 6 months like that, try to keep the RPM's low.

FLICKING LIGHTS WHEN ACCELERATING


I suggest taking the car to an autoparts store and have the alternator output checked. Most parts stores will check the alternator and battery condition for free. Flickering lights can be a sign of voltage fluctuations and getting the battery and alternator checked may narrow down the cause. Sorry for your trouble and I hope this helped. Best wishes.

1993 Lexus SC400- alternator has been replaced twice but dash lights and headlights continue to flicker especially when breaking. When driving car the first 15 min or so it shakes and makes loud grinding...


First have battery checked at a Interstate battery place or equivelant. All issues point to low voltage. A shorted battery will cause the alternator not to work.

Your alternator is dead/dying. Nissan puts both of those lights on to tell you that the alternator isn't charging your battery.

Flickering charge light


my car started running like ****, gauzes on dash went to 0 and then would shoot back to where they should of been. parked car, shut it off and then it wouldnt start back up. jumped it and drove home- the whole time it bucked and spitted and wanted to stall. had the alternator replaced and then immediately the volt light started to flicker- i have left my lights on numerous times which contributed to my needing an alternator so i went and got a new battery. so far so good. it has only been a couple of weeks since all of this happened so it might be a little premature to think that it is solved. but for now it works!
