So, I have have an intermittent flickering of the battery light. The weird part is that it ONLY happens between 80 and 85 mph. Any faster or slower and it doesn't happen. It's not a steady flickering, but a random intermittent flicker. What the issue may be? The car has a new (within 2000 miles) battery and alternator. 1.8t with manual transmission.

The battery light on the dash is flickering...mostly off, but the light (battery symbol) lights up ever-so lightly...then off, then on...on for about half of a 45 minute drive last night. Voltage regulator? Alternator? The battery seems fine, as it turns over after a cold night...

So here's the deal. I first purchased the car about 2 months ago. Aside from preventative maint (plugs, coils, new fluids, oil, filters, etc.) no problems with the car whatsoever. However, I noticed at night with the lights on, the instrument cluster and every now and then the lights will "flicker". Not knowing when the original owner replaced the battery, if ever (it was an OEM battery so I wasn't positive), I figured maybe its a sign the battery was going.
So I replaced with an OEM VW battery a couple weeks ago (less than 1000 miles on it) and it appeared the problem was corrected. The instrument panel and even headlights, seemed brighter too and no flickering! Then last night, I noticed it was happening again. There is no problem with the car, except for the flickering, and I'm wondering if its not the battery, is it the alternator? What are some other problems I might expect to see if it was? Do I just get a voltmeter and test? Is there an electrical wiring issue somewhere?
Not sure if it matters but I did do a search and noticed some people have had problems after a rain storm. Im in NC and it rains almost every day or every other day, most of which I'm not driving the car but it sits outside. It did rain the other day when I noticed it happening (not while driving just prior to me driving). ALso, no CEL or Alternator Workshop.
Just put a side post battery with top post adapters on. I drive to town the battery light was flickering with every little bump finally it turned off. Got to the house car shut off tried to turn it on and nothing no click nothing. The dash lit up half way the radio flickered on and off constantly and and the ebrake light flashed with a beep. I'm at wits end. Just bought a tire and battery and filled the tank and now this happens. 2000 jetta 2.0 GL.....
View 1 Replies2009 3.3 GLS ... Yesterday my wife told me that the battery light in her Sonata was flickering for just a fraction of a second at a time at irregular intervals. Nothing else was an issue so we didn't think much of it, started fine, no other lights.
She just called me to tell me that on her way into work it started very hard, all the lights on the dash were flashing, the engine was stumbling and wanting to quit, and the radio is no longer working.
It will be several hours until I can get to it to check it out, but my first thought is to check the grounds. I haven't worked on this vehicle in the past so exactly where to look first or any other issues I should look for...
2003 - Just recently my battery light started coming on and off on the dash, and occasionally my headlights would turn off and come back on. Now the ABS and BRAKE lights flash and the headlights are still on and off. I have already scraped (not cleaned) most of the corrosion off of the terminals on the battery and tightened the connections...
View 3 RepliesToday my 98 Expedition just started at 50 mph or 3000 rpm with battery light flickering and voltage fluctuation toward high end of 18 volts. Battery is 1 month old. No problems under 45 mph or 2500 rpm.
View 7 RepliesI have a 2000 Ford Excursion XLT 2WD with just over 155,000 miles on it, for awhile now My battery light has been on and off or it'll flicker and some times it will even stay solid. I checked the batteries and the alternator a while ago and got good readings from them. I just thought it was a code that never got reset. Well this morning I was driving it and I noticed that when I brought the RPMs over 3,000 the battery gauge would go up to 18 volts and the battery stayed on until the RPMs went back down past 3,000. It did this all morning until I got home and just for kicks I put it in park and revved the engine up to 3,000 RPMs, when I did nothing happened. I tried looking online for an answer and I called a few mechanic shops who all said it was my alternator. I want to make sure that it is in fact the alternator....
View 13 RepliesOver the past few days the battery light has been flickering and at times staying on. In using the gauge cluster diagnostics, I am getting 12.4 engine off and 13.8 - 14.0 with the engine running.
Even when I'm driving with the battery warning light on I still get a consistent 13.8 - 14.0 (and I do have the headlights on, the A/C running, radio, etc).
Kind of scratching my head on this issue since it appears the alternator and battery are working correctly.
When I accelerate to merge onto the highway or pass my battery light blinks as well as my headlight flickering and a slight loss in power. My car has 140k miles on it, original battery which seems to test fine on my charger. I just change the spark plugs.
View 9 RepliesOver the past weekend i noticed all the electronics having a slight "flicker", so I figured my alternator was on its way out. After replacing the alt with a reman, I still had the issue. Then, replaced it with a new new one and the issue still persists. I will be getting a meter to test later when my buddy gets off work. The gauge on the dash is running high and battery light is flickering. Is there something I am missing? I ran another ground to frame also.

Both key fob buttons do NOT work but they will manually unlock the drivers door and drive the car. They both had batteries replaced.
Also, every time I open the door, the interior lights will flicker on every 3 seconds until I start the car then it goes away.
So last night my son left the one of the interior lights on and when I locked the doors they started flickering...
Totally clueless of what is happening, just now I was taking a video of the issue to post here when I noticed on the dmf showing the trunk lid like open flickering also is that where the problem may be...? I checked the bulb in the trunk and is on and working including the led stripes that put there to get more light... I taped on the trunk bulb...

We began to get an intermittent cruise control failure (big exclamation point in the lower left of the MFD and no green "cruise" when the lever was clicked to "on") in my wife's 2007 2.0T Passat several months ago. During the same period she told me that the car occasionally didn't want to crank...although it always started on a second try. Well, to make a long story short, I had the battery replaced at the 60K service a couple weeks ago and the cruise has worked flawlessly ever since.
I put two and two together just before I took it in for service when the car showed failure of the antiskid system in addition to the cruise following a particularly difficult start. Sure enough, the new battery fixed it. Apparently some of the accessory systems go into a failure mode when they don't get enough current on startup.

So I got a phone call from the wife and she tells me when she is driving, the Battery Symbol Light in the dash is lit up only when the Blower is on, but goes out when the Blower is off.
Also, when the vehicle is in Park and idling, the Battery Symbol Light is on but if the engine is revved up, the Battery Symbol light is not lit.
This would lead me to believe it may be a weak tension on the serpentine belt.
I will check both the tension on the belt and the voltage level tonight when she gets home from work, but I am puzzled, because my experience with alternator is either dead or alive. Not just a little dead.
2002 santa fe gls v6. I recently brought the car used and it appears to be in great shape with 135,000 miles, however the car has issues which I'm hoping are minor. Here are my questions:
The brake light and battery light stay illuminated, can this be a bad alternator? Speaking of alternator there is a rattling sound coming form the alternator area, do the bearings go bad? If it is the alternator, does it matter if I use a 95 or 110 amp? Is the alternator difficult to replace?
There is intermittent jerking when in drive. Is it possible that a malfunctioning alternator not delivering proper voltage can cause this type of issue possibly affecting the system computer? Could the jerking be due to something else like crank position sensor?
As I'm driving along, I get the battery light coming for a few minutes then going out. Is this a sign my alternator is on the fritz?
View 7 RepliesWell today I got an intermittent battery light so I got the batteries tested and they were both good and then the alternator is only pushing 12 volts so I guess I need a new one right? Which know should I get? And how hard is it to get the belt to relieve tension...
View 14 RepliesAbout a week or two ago, when driving home, my battery light flicked on while at a stop light. Also, as the light wen t green and I accelerated away, I noticed a kind of 'whine' from the engine, like a turbine spinning up. By the time I got home it was fine again and the light out, and has been until today, when it happened again...I noticed that it happens if I have the AC on and I'm at a stop. If I turn off the AC when waiting at traffic lights, that seems to eliminate the battery light, but I still here the whine.

Had problems with battery light. Was intermittent. Battery cables wouldn't stay tight, replaced them, light stayed off. Light back on now, constant. Battery reads 12.5ish off, 14.3ish running under load (lights, AC, etc.).
When truck is started, even cold, it doesn't rev up the RPM's and then die down to idle speed. It just goes straight to around 550rpm and surges slightly up and down between there and 650ish. Can these be related?
I have a 2004 Chevy Malibu Maxx that randomly dings and shows me the battery light.
It usually happens when going uphill or during really hard accelerations.
It is also showing OBDII code P0621.
The car has no other issues. Always starts, always runs well.
What causes this problem? Where should I start looking? I'm thinking it's probably a bad connection somewhere.
