195K, B5, 1999, AEB. 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...
View 6 Replies2003 - 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 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.

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.
View 3 RepliesThe last month or so, I have noticed that my dash board lights (red lights) and my actual interior lights that come on when you open the doors to vehicle will flicker sometimes...And it can get bad I guess and annoying. It's more of it pulsating really. I noticed today while driving home and I had the radio on loud it was doing it and I do not know if was just in my head that it was doing it more when the radio was loud or what, but this is ridiculous.

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...
Today 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.

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...

I started the car this morning, plugged the phone charger into the lighter socket, noticed the charger light wasn't on, pressed the charger in tighter, the car started to run funny, then it cut off. Lights work, radio won't work, all fuses are alright upon several visual inspections. Car wants to turn over but won't start. I tried disconnecting the negative battery cable to see if the car would revert back to "normal". I have never had a problem with this car in the two years I've had it; the battery was purchased brand new in November of 2011. I unplugged the cigarette lighter to see if that would work but nothing so far. Could it be the ignition switch?!
View 3 RepliesI have tried resetting the ECU via fuse pull. I have confirmed brake lights work (as do all of the lights). Car has just 66K and simply will not start at all. Battery terminals clean and connected.
ECU?

This thing is a blast to drive, but has so many issues and is not stuck in my garage!
the flickering stopped after 10 mins and hasnt come back. is this an alternator problem or loose battery cables/ground strap?

Yesterday the headlights did not turn off automatically when the car was locked up after being driven for about 30 minutes. Unfortunately, this was not detected until about 8 hours later.
The door locks would not function with the remote and the doors were manually unlocked.
When I got in the car and tried to start the car the dash and dome lights began blinking/flickering, the CD player ejected the CD, and the security light was blinking as it would if the doors were still locked.
The battery was too low to start the car so I jumped the car to start it and got home.
Battery showed 12.7 volts cold the next morning before the car was started. While running there was about 14.3 volts across the battery terminals which would seem to say the charging system is OK. Battery is just under 3 years old.
Doing some testing, I found that the headlights would turn on with the multifunction switch without the car running. In this case they would not turn off through locking the doors even after double clicking the lock button on the remote. The only way to turn them off in this case was through the multifunction switch.
Other testing shows that if the lights were turned on with the car running, they would turn off automatically within about 30 seconds or so when the car was shut off and the doors locked. In another similar test with the engine running and then shut down I also tried the double click lock using the remote and this also turned the lights off immediately.
Based on research on TN site, one recommendation for a similar, but not identical, problem was to replace the multifunction switch. No one suggests replacing the headlight relay or any of the 4 DRL relays.
Randomly for the past couple of weeks, my 2009 2.4 automatic has the transmission letters on the dash rapidly flickering... ex.: driving in D, the display flickers D-P-D-P or D-N-D-N etc very fast. It's not happening in Tiptronic mode and the car is driving very well with excellent mileage.
From what i can see, this happens when the car is in motion only. My thought is a bad contact at a sensor somewhere that loses contact on and off with bumps in the road, but not when stopped? The car has only 50,000km.
It is still under extended warranty, therefore a 50$ deductible for any repair under warranty... whatever issue i had with this car was always intermittent so the dealer won't fix anything if they cannot see the issue and have the nasty habit of charging me like a half hour for trying to diagnose without success. Guess what happens every time I drop off at the dealer? issue not present of course.
So I swapped out my OEM battery for one straight from Hyundai and during the first night time drive, I immediately noticed a very severe flicker with the lights (headlights, interior and trunk) when idling that was definitely not there with the original battery. I have already done the ground strap mod so I went back and re-cleaned the grounding points and even filed down the grounding post on the new battery itself but the problem remains.
I'm thinking I either got the wrong battery or a bum one and the alternator is only a year or so old.
I have a very strange electrical issue and CarMax is unable to find the source.
Detail of issue: It started 2 months ago before i left the country i took my car in to get the dreaded valve gasket cover and alternator and after taking the car back i left for Europe for 2 months. I was informed after 2 weeks that my car battery died and had to be jumped.
When I returned home I notice the following issues
1) Alternator Whine in my Sound System
2) Low frequency noise synchronized with engine rev that was triggering the sub low end making a very distinct wooom.
3) Sudden Power Loss for my secondary AMP. The base would cut on /off.
4) Light flicker in my Dashboard (only the GEAR LED) and the entire climate LCD. flicker also synchronized with engine rev.
5) POWER drop on the air con fans while breaking (the RPM would drop)
6) I saw the headlights where also flickering at the same frequency with the LCD and dash led a very noticeable flicker.
7) my headlights would dim when breaking.
8) My Car would start a bit slower (not as instant as before).
Initially i thought it was the my secondary amp that was causing the issue. I took the car to a great Audio shop and they said the On board Hyundai amp was sending weird signals. They said it was broken and i should have it replaced. I told them to disconnect the AMP from the car and leave it disconnected until i take the car back to Carmax.
I was hoping that was the cause ... it wasn't the lights keep flickering (at a far lower intensity probably due to the lower power consumption overall).
What could cause all of this. Alternator I had the alternator replaced two weeks ago (apparently it was broken). I changed 3 alternators in this car. Valve Gasket, Valve Gasket(they were retarded and didn't listen to what i told them) and broken.
