Ford Super Duty (1999-2016) :: Idling At Startup Make Truck Deliver Power Smoother / Battery Light Stays Off
I would like to know what's happening, it seems as if idling for a minute to let my transmission temperature dial raise past the lowest line on the dial fixes or at least drastically reduces a couple issues.
The truck will deliver power much smoother off the line. I've been concerned about this for a while. The degree to which it happened wasn't constant but it seems like the truck is having trouble grabbing on (so to say) to the power coming off the line. I sort of liken it to a rope. When I give it the beans the rope goes forward but it takes a half a second or so for the truck to "grab" on to the rope. Never hard shifts, it's just delivering the power off the line or from a near stop.
Idling for a minute seems to fix this, power delivery is smooth off the line. Transmission dipstick was nice and pink but smelled slightly burnt. This is with the engine cold overnight. Didn't have time to do multiple wipes or check in the handbook for the proper methods of checking fluid, I just pulled it out quickly to take a look before heading out. Fluid covered the whole tip.
Second issue that seems to be fixed is that the battery light doesn't come on nearly as much and not for nearly as long. Typically the battery light will come on and off seemingly on its own whim during the drive. However, it seems to stay more consistently off if I idle right after startup.
Now bear in mind I baby my truck, I don't rev it high right after startup. Just low enough to cruise around the parking lot until I hit the road then I accelerate up to 40 - 60 depending on my route. I'd gladly give it the minute to warm up in the future but if I could get down to the bottom of this that'd be preferred, I doubt this is required behavior.
I do realize that these issues are not tied to startup behavior but I find it interesting that idling for a minute at startup to let the transmission gauge rise seems to mitigate these symptoms.
Ford Super Duty (1999-2016) :: 2003 F250 - Battery Light Came On Intermittently?
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
Ford Super Duty (1999-2016) :: 2003 - Battery Light Comes On Only After Reaching Operating Temp
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.

My 4x4 on my 2000 model f350 will not engage. The light works, comes on briefly on startup of the engine. When I flip the switch nothing happens. When I jumper the relays nothing happens. I do not have the factory hubs, they r warn hubs and the vacuum line to them is capped off. How to figure this out on why the 4x4 will not engage?

Trying to do some trouble shooting on my own as I'm tired of spending $$ with my local "diesel" garage and getting ripped off. To start with, here's my symptoms:
1. Hard (very hard) to start in the morning. Gets harder every morning. Took me 10 minutes of cranking yesterday morning
2. Once it does start it's very loud, seems to run on just a couple of cylinders and lot's of white smoke
3. After about 10 minutes it's able to get down the road but then at about 2300 RPM and above it sputters, low power, and LOTS of white smoke again.
4. Lots of diesel smell, almost like it has a leak but no visible signs of leaking anywhere.
I've done a lot of research and seems to be leading me towards injector problem or in that general vicinity. However, my first step is to try to narrow it down a little more before I start throwing parts at it. So, first question is: what's my best option for downloading codes? I guess I need one that is CAN capable but seems like most of these or either a few thousand $$ or I have to go to something like a Scanguage or Bullydog. I've thought about putting a tuner on but I guess at that point I'm committing to keeping the truck for a few more years.
So, just initially looking for info on diagnostics equipment and/or test that will eliminate the issue(s). Second, need inputs on possible problems based on symptoms listed above that would be great too. Had EGR delete done a year or so ago.
Ford Super Duty (1999-2016) :: Battery Light Won't Go Off
I've got a '03 F250 7.3L 4x4 (not sure how much info you need) with many many miles. My battery light came on a couple of months ago. Replaced a battery. Light went out for a day. Checked and replaced the alternator. Light went out for a couple days. Cleaned the battery terminals for better connection. The battery light is off when I first start the truck, but depending on what I've got turned on, lights, radio, AC, the battery light comes on with in 15 to 30 miles down the road. I had the batteries and the alternator rechecked yesterday and everything seems to be charged and charging.
- Should I replace the wiring to the alternator?
- Are there any fuses I should be looking at or for?
- The alternator is a rebuilt one from Autozone, should I get a new one?
Ford Super Duty (1999-2016) :: Battery Light Came On
Battery light came on today, I figured were in need of replacement so I got new ones. Light is still on, until I reach about 1800 rpm. It goes out until truck idles down. Can an alternator do this? I always thought when they went, they went.

2005 F-350 6L diesel .... Put new batteries in it a week ago.
Been running good then the radio quit a couple of times. It came back on after truck was restarted. This morning I go to town and the battery light comes on. I stopped and started about 5 times and on the 6th it wouldn't start.
I got a boost and started home it , started to try and quit when I was almost home. Was so dead the power windows wouldn't even work. Have it on the battery charger now and it starts right up but the battery light is still on and the ABS light is on.
Ford Super Duty (1999-2016) :: Battery Light Coming On Intermittently?
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.

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.

I started to notice my battery light comes on during a hard acceleration. So I have been keeping track of it. When the rpm's hit 3200 and above the light comes on bright but never at any other time. I put a volt meter on it and I have 13.4 volts at an idle, as the engine revs up the voltage climes to 13.9 then when it hits the 3200 mark voltage drops right off to 12.4. It seems like a regulator issue to me. The parts store says my 5.4 has an external regulator is that so or is it built right into the alternator?

The battery light is on on the dash. I checked both batteries with the ground wire removed, and they show 12.85 and 12.84 volts, they are clean and not in need of water. The battery light will go out after around 15 minutes on the highway, but not around town, and if I shut off the truck in town, the next start is at a very reduced amperage. Alternator packing it in?

I have a 1999 f-350 V-10. My battery light came on, making me believe that my alt. has quit. I can't see the plaque on the alt so I can't tell the amps. Does my serial number on the truck tell the amps, or do i have to remove the alt to check the amps?

Thought it must be my starter then , bought a $200 starter and changed it , still doing the same thing. It did start after changing the starter but wont now.
Neutral safety switch?
Ford Super Duty (1999-2016) :: 2003 F250 - Alternator Not Charging Battery?
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.
