Ford Super Duty (1999-2016) :: Battery Light On But Alternator Is Charging?
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.

Pretty much as the title says, I'm having an interesting electrical gremlin. Ford 7.3 super crew 2002 lariat LE.
I have batteries from 2015 that are losing their charge, both of them. It's like the alternator isn't charging them. Truck will struggle to start until jump started, then she's fine.
Symptoms are:
ABS light comes on when as best I can tell the batteries aren't getting charged. Not the battery indicator.
Now that the batteries are low enough, on the instrument cluster the little light the powers the mile LCD screen dims when it's not getting power (but it's fine when the batteries have charge.)
All accessories work when driving, but I haven't been able to drive a long while on the "not charging phase" to see how low they're go.
Batteries register dead (now) because they haven't gotten charge in a while.
When the alternator IS charging or "connected" I can leave the truck idle and she'll charge the batteries, truck will start just fine on the next run (no parasitic drain.)
Driving causes this to happen randomly, doesn't happen when I'm stationary, nor do I believe it CHANGES state (so if I'm idle it won't suddenly NOT charge if it was charging before.)
Narrowed down to 2 probable things.
Alternator
Bad alternator to battery cables
Ford Super Duty (1999-2016) :: Battery Light Flickers On Highway Having 50% Charging - No Alternator?
for some reason my battery light flickers when im driving regular and on the highway. I have had both batteries checked and they were at 50 percent charge and both were good so therefore I assumed it was my alternator. I removed alternator had it check and it passed all test. Everything was checked at o'reilly and autozone

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?

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.

I replaced my alt. because in the morning the bearing would squeak and the head lights flicker. It was a life time alt. Put the new one in now it wont charge. Took it back and got another, same thing. Also replaced the starter relay and battery. I checked the fusible links and replaced a terminal connector. The wires look good. There is 12v on the alt lug and pins 1 and 3 on the connector with the key off. Turn key on and 12v disappears form pins 1 & 3. Also checked all fuses in both boxes. I ohmed out the wire harness from the alt back to the connectors, all good. What am I missing? This is a 99 f530 5.4l.

I went to start my 2006 F350 6.0 this morning. 20 degrees outside. It nearly turned over, then it appeared that the batteries would not support another start - a slowing of the pre-engine start revving....
So I let it sit a while, now it won't start at all. When I try to start it, the dashboard flashes, clicking sounds occur and even after pulling out the keys, the needles on the gauges shake for a few seconds.
Is this more a battery issue or an alternator issue?
Ford Super Duty (1999-2016) :: Radio Quit After Battery Change
I just changed my batteries in my truck. Twas the originals still in it. Afterwards, everything works except the radio. I tried everything and no radio. The clock is there when I press the On/Off/Volume. When I press the phone, the display says "no phone". But otherwise I get nothing. I can't even get in the menu to set the clock. I checked the fuses related to the Amp, Subwoofer, radio, Satellite, etc. I did not see anything in the fused under the hood that could be related.

My trouble is that the alternator light on my 2004 F-250 Diesel began to come on occasionally, but never constant. Taking in the fact that it was still the original alternator, and over 70,000 miles, I figured it was time for a new one. I installed the new one and after two days the light came on again. I tested the alternator and it read 13.84 volts while running. With the engine shut off, I had 12.59, and 12.6 volts at the batteries. What may be my problem? Diesel down.

My 05 F20 CC LB 6.0 4WD has the alternator light on for a few miles then goes out also sometimes goes away when you accelerate hard, is my alternator going, or is this some common glitch in the light hopefully?? Also every once in a while got the death wobble, installed tie rod ends and center link, but if I hit a bump just right it does it.
View 2 RepliesFord Super Duty (1999-2016) :: Alternator Light Flickering Then Stayed On / Ticking At Idle
So my truck drove great to ocean city MD this weekend. Power is perfect again, feels really tight. But now I have having to additional problems.
1) My alt light had been flickering a couples times a month. Last night it came on and stayed on. Lots of threads about this I Know!
I am hoping that cleaning and tightening the connections will do the trick since the alt is a Bosch with only 25k miles or so. But I want to order a rebuild kit:
is my alt a 3G or a 3G8429?
F SERIES | Alternator Starter Rebuild Kits
2) I started to have a ticking at idle. Its very regular and sounds like its coming from the passenger side valve cover. In random threads I have read about timing chain guides breaking and loose rocker arms.
Most of the time its 3 ticks in a row and then a pause. Should I be pulling the valve cover? Think I need to R&R the timing chain? I will post a video later!
Ford Super Duty (1999-2016) :: Speedometer Quit Working And ABS Light Will Come On Occasionally
Occasionally while driving my 2005 F250 the speedometer will quit working & the abs light will come on. The transmission will also start to shift weird. If I pull over, shut the truck off & restart it everything is fine again. I can go weeks at a time before it happens again, but yesterday it happened twice. The transmission doesn't seem to shift real fast, but I think that is a separate issue. My first instinct is that the rear VSS is starting to go out, but I am not sure if these symptoms are common.

We've got a 2012 F550 6.7 with 138k. It recently got a battery light. The batteries are right around 12 volts with the truck running or off.

Where to look next?
