Ford Super Duty (1999-2016) :: Changed Alternator And Now Have Battery Light On
I put an O'reileys alternator in my truck today. Drove it most the day and did some plowing with it and it was fine. I just went out to run to the gas station and now the battery light is on. The voltage is still good.

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 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?

My alternator quit charging last night. Was pretty much a sudden onset as I was driving down the road and left off the accelerator the battery light came on and lights dimmed a bit. When I stepped on the accelerator again they bat. light went off and the lights came back up.
At idle I'm at 11.77v. I've pulled the plug on the back of the alternator and I'm getting voltage on both the red and green wires that go into the plug with the engine running. Is this correct?
Ford Super Duty (1999-2016) :: ABS Light Turns On When Alternator Is Not Charging Battery
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

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.

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.

I have a 99 f450 4X4 I'm having brake problems. Without warning when I go to stop my peddle will go right to the floor and I can't stop, at other times I go to stop and the peddle is stiff and I have to put all I have in to it to stop. The abs light comes on and off occasionally at random but as the brake failure has become more and more frequent so has the abs light. Also my steering does seem a bit off, a little tough N jerky and the power steering pump is whining.

Got my 240 amp alternator in and had all new 1/0 GA battery cables with a 250amp fuse in line made to do all new lines. I started tonight and found a small line going from the alt connector down the power line to a fuseible link (fuse) all in the power line
I wanna do away with the main 4 ga alt wire but obviously I can't do anything with that line going to the plug. Can I put a connector on it and wire that into the one side of the 250amp fuse.
The only other option is to add a wire to beef up the stock line ....
Ford Super Duty (1999-2016) :: 2000 - Installing Second Alternator?
The V10 in my service truck took the long slow ride. I located and am in the middle of replacing said engine. My question is, how difficult would it be to install a second alternator in this truck, considering I have it torn down for replacement?
It a 2000 F350 with a V10. I'm looking for more power as I have mounted on the Knaphiede service body a IMT 1015 crane, 3200 lb capacity. I would like to install a power inverter to be able to run an air compressor in the field.
Am I looking for a new harness? Etc?
Ford Super Duty (1999-2016) :: Whining Noise From Alternator?
I have had this whining noise that I'm not sure what it is. It sounds like its comin from the alternator area. There are three symptoms that are confusing me though, 1st is I only hear this whine as the weather starts getting colder and the colder it is the louder it is. 2nd is it only happens around 1800rpms like when it's getting ready to shift to the next gear. I can get it to whine when I'm parked and bringing the rpms up. 3rd is after 10-15 minutes when the truck is warmed up - no more whine. The truck is used very little duing the summer and I had this whine all winter last year. Alternator appears to be working fine and I do plow a few driveways every storm. Money is tight so I don't want to replace the Alternator an find it wasn't the problem.

I was running my 99 F250 SD with the V10 around the DFW area pulling a car hauler with a Jeep on it. The last 50 or so miles on the way home she started shuddering at a constant speed unless I turned off the overdrive or I was accelerating or slowing down.
She's never given me any issues but this is bothering me. 4x4...
Ford Super Duty (1999-2016) :: New Rotors / Pads But Constant Squealing?
I've replaced the pads and rotors on my 97 f250 HD, only to have constant squealing. I've replaced ranger rotors before with no problem but this has been an adventure. It's squeals constantly up to 35, (I've only went up to 35) and squeals louder under braking. Just looking for some pointers. Probably just need a good cleaning. The truck is parked until its fixed more than likely.

I am really hoping that my instrument cluster in not working because my alternator went out at the same time. I really hope they are connected somehow. I really need a wiring diagram for this one. Just got the truck last week and have been taking care of the little things to get it fixed up and make it my own. my new rear step bumper came in today. I will be dropping off the the alternator for a rebuild tomorrow. So looking for a wiring diagram?

I have a 2001 F350 with a7.3 power stroke, 6 speed manual with manual t case and hubs. I have a bad grinding noise when in 2 wheel drive. Similar sound as if you are trying to shift t case into 4 wheel drive too slowly. The grinding is constant in 2 wheel drive, but if I shift it into 4 wheel drive, the noise completely goes away. I have been driving around in 4 wheel drive (T case only, manual hubs not locked) for the past 2 days. If I shift back into 2 wheel drive, a constant terrible grinding noise returns. What could be wrong, and why it goes away in 4 wheel drive?????
