Ford Super Duty (1999-2016) :: 2003 F250 - Battery Light Came On Intermittently?
Jan 5, 2015
I have a 2003 f250 super duty with a v10
i was towing a trailer up and down lots of hills and the battery light on the dash came on. there was no effect on the performance right away. as i kept driving into town i was starting to worry if i would make it.
as i pulled into the carls jr parking lot, the ABS light came on, all the gauges shut off and the truck died just as i pulled into a parking spot.
i figured it was the alternator, had it tested at AutoZone (failed twice) so i swapped it out for a lifetime warranty AutoZone one (very small town, nothing other than an AutoZone)
the truck started after being jumped but the battery light was still on. i figured that the bad alternator killed the battery. the battery was 4 years old and they usually only last 3 years in the AZ heat so i bought a new duralast gold.
the battery light was STILL on after that. the Autozone guy ran his test--- engine off- battery tested fine starting---he said something was wrong with the starter (but it cranked awesomely!) running--alternator tested fine
i just can figure out why when i drive down the road i dash light will turn on and off at random times. the truck seems to run fine. I've even been under the hood shaking the wire while i had someone watching the dash and i cant seem to make the light go on or off

03 f 250 super duty, my battery light came on and when I accelerate my dash gauges shut down and radio turns off, if I idle or stay under twenty MPH, everything works fine. Battery and alternator test good, lights never dim, any thoughts

I have an 06 F350 with the 6.0 powerstroke. My battery light started coming on and will go out for a while, then come back on. Sometimes it flickers a little. I have checked/cleaned battery terminals (there was no corrosion). I have replaced the alternator. The batteries are just over a year old (10/12). I have not had any slow starting or any other symptoms other than the warning light. I am still having the same problems after replacing the alternator. I have checked with a voltage tester and it was reading 19+ when the light was off. When the warning light is on it was jumping from 12 - 15. This is an old tester so I'm not sure that it is working correctly. (not sure why I am getting the 19+). I'm going to go buy a new tester, but I was wondering if there is something else that could be causing the warning light. I know very little when it comes to electrical issues.

Took in the alternator to get it checked and they said it was good. Put it back on and it seemed like it was charging according to my volt meter (14.24-13.5 v)
Today, it's not charging. Only reads 12.2 v while running. Is there a fuse or something I need to check? Grounds? It seems intermittent.

2004 F250 v10 xtl 260xxx. Started off by using my remote start, truck started up ran for about 5 sec then shut off, then restart itself and shut back off. When I manually started it, it ran fine. I noticed my battery light was on and as I was driving it would flicker. First thing I did when I got home was clean all my connections to see if that worked. Battery light still on, checked my volts on my battery and they were at about 11.8 with a slow but steady drop while truck was idling.then checked my alt, that too was at about 11.9 with a stead drop.
Alt was only about 7 months old and I had a warranty on it so I had it replaced at Napa and had them test it there. Good alt. Installed the new alt charged up my battery and turned it over. Battery light still on and flickering. Checked all my wires for corrosion, checked all my grounds. Everything checked out. Checked my battery again 12.4 with the truck off, cranked it over and it was back at 11.9 with a steady drop and almost the same reading with the alt. I replaced the battery as well yesterday, seeing how it was about 7 years old.

I was driving and all of a sudden the radio died, battery light came on, Power windows and interior lights died, gauges died speedometer went all the way up to 100. The Head lights, turn signals and heater work. When I got home I opened the hood and the battery was boiling.

I've been having issues with the charging system on my 2005. The battery was 7 years old, so I replaced it. Now, the battery light comes on dimly (and flickers) when at low RPM. I am thinking alternator. I replaced one on my 2002 F150, but haven't done a 250. How hard are they to get to and replace? This is on a 5.4 gasser.....

Long story short: I bought my 2003 F-250 super duty 6.0 used back in January. It had one Ford OEM battery and one Walmart special. I had them tested and they were both completely flat. Replaced the set of batteries the next day. Since then, upon cranking the truck, the battery indicator will be illuminated while the truck is running. It will stay on for a length of time that varies based on the day. It will eventually turn off after driving a while, but will come back on if I kill the truck and crank it again (like when running to a store).
The batteries have been tested 4 times and test just fine. No problems with the batteries. The OBD 2 computer/monitor I have installed reads a voltage of around 13 when the truck is running. What to do to solve this problem. It isn't a major issue as the truck always cranks fine and the batteries are not damaged or anything, it is more of a annoying thing. It bugs the crap out of me.

OK, quick question. I have an '03 250 with the 5.4 and the OD light began flashing tonight. I looked in the forums here and everyone say's new tranny or sensor but over on the diesel forums the are saying that the alternator is a big cause of this (dirty power).
At the beginning of this year I noticed what I assumed to be a misfire when putting the motor under a load. Once up to speed it would smooth out and all was good. I was told that a plug job on these trucks is hellish and expensive since a lot of guys break the plugs off in the block. I put it off and the issue went away when the weather warmed up.
Now it's getting cold again and the misfire is back. Driving home tonight the truck died at a light. I restarted it and as I accelerated I noticed a difference in the shift from first to second and then saw the OD light blinking.
Again, the diesel guys are all talking alternator so my question is this: could the alternator cause both the OD light to flash AND the misfire? If the "dirty power" can cause the tranny to fall in to safe mode, can it also cause the ignition to be problematic?

So beating the dead horse here. I have an 03 6.0 that the batt light comes on only after reaching operating temp. Using fords self test mode it shows 13.5V to 14.3V, pull the regulator plug light goes out, A circuit has batt V and I circuit has no V Key off and batt V with key on. I have wiggled wires in the dash and under the hood replaced the reg plug. I feel as though I have read every thread with not much success.

I have a 2008 f250 with 5.4v8. The truck starts intermittently. Put key in turn if no dash lights it doesn't even crank or hear a click. If u put key in and turn and dash lights up to starts and runs. U can watch the different lights (instrument cluster) light up independently like a xmas tree. When truck doesn't start if u disconnect battery when touching power wire to battery. Post truck lights will flick on/off if u tap cables to battery and leave on. Lights flicker on/off and then stay off. (Don't know why shouldn't flicker at all) after disconnecting and reconnecting battery truck will or will not start still depends on if dash lights come on before cranking.i replaced battery, starter, alternator, all the ground cable connections and wire cleaned. I haven't replaced the power side but are clean.

My Blower motor is intermittently going on and off. After messing with it for a while it seems to stay on. Motor may be going out. Not real easy to change the blower motor on this 2008. Haynes manual says to take the 2008 and up trucks to the dealer.

I bought a crew from a dealer, all the dome lights and cargo lights had the bulbs removed, so i put them back in and of coarse they all stayed on after you close the door, plus the door ajar light stays on when you are driving. I do notice the radio shuts off when you open the door after you turn off the ignition. Does that work on the same door switch, eliminating those?
Also are there switches on the rear doors also? Noticed that the radio isn't effected when you open a rear door. I tried to get the dealer to look at it a day after i took it home, a ford dealer at that, and they told me they tried to figure it out , and couldn't before they sold me the truck. Doesn't say much for their service department.

The other day I was checking out my parking aids (they kept saying something was behind me when there was nothing there) and the horn just started blowing by itself, constant on until I disconnected the batteries. Been a few days and just got back to working on it, checked the horn switch in the airbag and it is functioning fine. Hooked the batteries back up, no horn, but after a couple of minutes I start getting little honks out of it, then locked on again. Where I should go from here? Truck was parked, switch off, engine off today when I hooked the batteries up. Never started it or turned the key on.

2013 F250. Wife turned the ignition on to roll up the windows before the storm (good thing), but left the switch on. Both batteries dead. I charged them both (although not completely). Started OK but have a check engine light on. Should I just put the batteries back on charge?

I just bought a 2003 F250 from a used dealer. Unfortunately the service engine light keeps popping on and putting out the code P0401, I have replaced the EGR, cleaned the inside, and cleared the code. However it continues to keep popping up and then it will turn off after a couple of days. I mostly drive in the city and the code generally only pops on when I drive on the highway. I have also noticed a lack or delay of power, when I really hit it hard, I think its because the computer is keeping the egr valve open. What it could be?

Problem started with the front end shaking a little bit when braking like the rotors needed turning. Then the brakes began to intermittently hum when stopping. Then my ABS light came on. Put the truck up on the stands and disassembled the brakes on both sides. The ABS sensor was chewed up on the driver side. The less than year old hub felt sloppy so I changed it. Put everything back together.
New hub came with new ABS sensor. Went for a test drive ABS light is gone and I no longer shake or experience the hum when applying the brakes. However now when I go to stop right before I come to a complete stop the driver side (new hub/spindle side) I hear what sounds like the grade school class clown making a fart sound with his mouth, and the truck pulls to the driver side. Is the ABS system malfunctioning or is this a caliper issue? Calipers look like they are OEM.

Like the title says, if it sits over night the battery will be about dead. The cables were replaced 6 months ago and are in good shape. I could not find and bad spots on the wires I can get to. One odd thing to note, with the key out of the switch I opened the passenger door to check the glove box light and the truck started chiming like I had opened the drivers door with the key still in the switch. Would that indicate maybe the key switch could be the issue?

So two weeks ago I had a battery melt on me and I replaced it. Then last week I had the other battery almost blow up on me (it was a mess and smoking). I didnt use it all weekend. Today it started right up. I drove it like 500 feet and it just died. It is very weird. Both batteries are fully charged. Relay is good. When I put in the key it does nothing. No sound no radio no clicking. However, the gps still works (the online monitoring kind). I can fold in my out revie mirrors. And I can lock and unlock the doors. and the interior overhead lights come on. Nothing else has power at all. And I can't put it in neutral. Right now the truck is blocking my driveway so nothing can get in or our of here. I am wondering if it is some type of antitheft issue...
