Ford F-150 (2004-2008) :: Battery Light On Dash Illuminates
About 45 seconds after start up Battery light on dash illuminates. Gauge shows in good range. Fluke meter across battery terminals reads 14.2 - 14.4 volts at idle with lights on high beam. No TDC's.
Truck is new to me, engine was replaced recently so I did do a check of harness connections with no problems found, what I should check next ?
Ford F-150 (2004-2008) :: Low Idle After Alternator And Battery Replacement
I just replaced my battery and alternator this evening on my 2004 F-150 5.4L. After driving it around a bit, the idle is dropping to about 100 RPM almost to a point of stalling when coming to stop. It slowly creeps back up to a normal idle shortly after.

The battery light came on in my '04 F150 a couple of days ago. Terminals were in need of cleaning, so I took care of that. The next day after driving 50 miles to and from work, the battery light came on again, along with the ABS & Brake light started flashing. After shutting the truck off, it would not start.
Three days later, I have now installed a brand new alternator and battery, only to have the same symptoms pop up about one minute after start up. The warning lights are now accompanied by the passenger airbag light and all engine instruments needle sweep back and forth. Dash lights go dim and bright intermittently as RPM varies.
Do I need old fault codes cleared or is this a PCM issue?
Ford F-150 (2009-2014) :: Alternator Failure And Battery Warning On Dash
2014 4x4 5.0 ... Drove my new truck (less than 1900 miles) to work in the rain. Alternator failed and battery warning on dash. Took truck to dealer, they confirmed and said not covered by warranty. Talked to ford, they back up dealers decision. They want a whole bunch of money to replace alternator and clean under the hood. What good is a 4x4 if it fails driving to work on an open highway?

My battery went dead so I replaced with new. This did not fix the problem so I replaced the alternator. It's working now but the battery light stays on. I think I still have a problem.
View 3 RepliesFord - Focus :: 2002 - Flashing Battery Light But Not Alternator Or Battery?
2002 Ford Focus SE with 130k miles on it. For the past 4 months the battery light flashes randomly while driving. The flashing and frequency of flashing doesn't seem related to anything I can tell including temperature, length of time the car is running, speed or any variable. Seems like it should be an alternator, but that was replaced less than an year ago and it also has a new battery. The alternator always checks out fine at the mechanic and it will never flash for the mechanic. It went 1 month with no flashing and suddenly it will now flash maybe 20 times in a 5 mile drive. Yesterday it just died at a stoplight with no warning, but then after shutting everything off it started just fine and the battery light didn't turn on for the 2 miles to home.

The past few weeks the dashboard warning light for my alternator/battery will occasionally light up while driving down the road. Whenever it does, my plug in voltage meter shows a healthy 14.x reading. It usually goes out after a few seconds, but will stay lit up for as much as thirty seconds. So other than voltage being too high or too low, what else will cause the dash trouble light to illuminate?

I have had my '08 Prius for 3 years and have little to no problems with it. This morning I jumped in to go to work and the entire dash lit up and then faded out and died. The only lights still on is the check engine light, Airbag light and the little green light on the Park button. The worst part is now I can not completely shut it down. I am wondering if it is just a dead battery or if this is something bigger. If it is a dead battery I am baffled at how it could be. I have AAA coming to jump it and I hope that is all it is. Sound familiar?

View 7 RepliesFord F-150 - 1997-2003 :: Battery Light On - Alternator Or Regulator?
The other day the battery light came on. Of course the useless "gauge" still reads normal but that is another rant.
Checked voltages today:
Battery reads 12.0 volts key off, 11.83 key on, engine off, 11.65 engine running.
Obviously discharging and I am guessing it is the alternator. Do these trucks have an external regulator that may have failed or is it in the alternator? I'd hate to spend $150-200 for an alternator only to find out it doesn't solve the problem.
Ford F-150 (2004-2008) :: Light On The Dash Comes On - 4WD Is Not Engaging
I have a 2004 F-150 Non Heritage. The 4WD was working fine last year and is not working now. The light on the dash comes on and I do seen to be getting vacuum at the hub but it is not engaging. Several months prior to using the 4WD I did do some front end work and must have knocked the vac line off. It was off for several months, I reinstalled it and it is still not working.

I bought my 2004 F150 about a year and a half ago and the cruise has never worked. I have checked the fuses (02, 14, 15) and all are good. I tried the diagnostic route with holding the off button but no cruise light ever comes up on the dash. You do have to push the brake to move out of park.

I have a 06 F250 6.0 My battery light has been coming on. Doesn't stay on but I'm planning a trip back east and don't want any issues to occur. I was thinking maybe the batteries. So I stopped at the local Oreilly's Auto store and had them tested. Told the guy what it was doing and he said it sounded like the alternator. He tested it and said it was going bad. He also tested the batteries and said they were good. So I went looking for a replacement alternator and they have different amp sizes. So I'm not sure on what size the original one is and if the replacement should be a bigger size amp wise.

OK I have 14.04 volts at the batteries with the engine running but my battery light is on. I had the alternator checked off the engine and on the engine and it tests good. Shows good batteries and good charging. Is there something internal to the alternator that would make the light come on even though the alternator is charging ok? Or is there something else that would make the light come on. This is on a 1999 F250 Superduty Powerstroke 7.3.

2004 Lariat ... My cruise isn't working, won't even come (no light on dash). I tried the self test where you turn the ign on with the E-brake on and try holding the cruise off button to enter some kind of diag mode but it didn't work. I found a video on youtube where a mechanic replaced some pressure switch on the master cyl but my master cyl doesn't have what the video showed. I read somewhere about the 3rd brake light having something to do with it. FWIW, my 3rd brake light does not work.

I recently purchased an 07 f150 lariat leveled 4x4. I noticed the other day that all at once, the abs light and parking brake light came onto the dash, 4x4 low doesn't work and just stays in high and the ac doesn't blow cold. I'm assuming this is somewhat connected considering this all happened at once but really just not sure.
