Ford 6.0L Power Stroke Diesel :: Alternator Warning Light And Lose Power Steering Soon After Brakes Got Stiff
Jul 18, 2015
I just wanted to share with you all a cautionary tale about belt tensioners and idler pulleys. I am now a firm believer in installing the aforementioned items when you replace your drive belt. 15000 miles ago I replaced the drive belt and didn't heed the warning of some here on the forum.
For the last month or two I have noticed what sounded like road noise which I dismissed because I had just had new tires installed that had a more aggressive tread pattern than my previous tires, I also noted that the ECT had been a bit higher than normal, like running in the high 190's to low 200's on average.
Well while driving today I get the alternator warning light and lose power steering and soon after the brakes got stiff, this was followed by ever increasing ECT which got to 242* before I could get it off the road and shut down. It is too early to tell if the noises and the ECT temp rise were the result of this tensioner going out...
For what its worth the only tools required were a 10MM end wrench and a bit of skin to get the job done.

I've got an E99 powerstroke. Recently it's been getting hard to steer, if not impossible. When I'm parked i can't turn the wheel and it gets better if i Rev the engine up, driving is usually ok and going around corners. It's just low speed, low rpm that it won't.
Also every once in a while when braking it feels like i lose all power brakes. The pedal goes to the floor and the brakes let go, then i can feel the pedal pump back up and i get a good feeling brake pedal again that actually stops well. All this happens within about a seconds time. But the steering is by far the worst.
I just did the power steering flush with atf and it didn't work. I'm thinking i need a new power steering pump, but want to ask here first to make sure. The truck has 290,000 on it, and it never has been replaced to my knowledge. I bought the truck with 147,000 however so it may have been done before that.

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?

My 2003 ford expedition with the 4.6 v8 engine is having an issue i cant seem to pin point. The lights will get bright and then dim and the engine will die and I will lose power steering and brakes, it will start back up when i put it in park. Also while I am driving randomly the rpms will shoot up to between 3 and 4,000 rpms and go back down. I have seen a video on youtube that says the fuse box in this model is very likely to short out and ruin the circuit board. Mainly looking for any experience any of you have with a issue like this. The check engine light is on, Showing two codes for running too lean and a code for Idle air control valve. Mileage is 239,000 ...

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.

I picked up a 2003 6.0 awhile back went ahead and did studs,gaskets, delete. Was driving it and seemed to lose power, started coughing and carrying on blowing bluish white smoke then shut off. Ended up hydrlocking #5, Oring on injector was tore when took out. Put all back together, ran horrible, did a balance test with AE, showed #3 injector, replaced, ran horrible, did AE dropped #1 injector. So in process of replacing the rest of the injectors. Just wondering why it is or was dropping them 1 at a time. Ficm was showing 47.6 to 48.6 volts, could that be it?????

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. I also tested the output on the alternator and its not charging. I put a new alternator in it and still no charge. All the connections are tight and clean. The batteries load test ok. Where to look next?

So I have been having this little issue for a few weeks now. I will be driving along and out of nowhere my batt light will come on and my gauge cluster,radio and windows stop working and the ficim volts jump to 15.5-16.5. This is an intermittent issue. Yesterday I put my multi meter on the alternator and I am reading 13.5 or so this number was done at idle and the batt light was NOT on .

My 2006 F250 has a single alternator and recently the charge light is on intermittently and I have watched output voltage fluctuate between 12.4 to 13.5 ... sometime a .3 volt bounce one way or another for no noticeable reason.
So rather than buy a new alternator, I would like to replace the voltage regulator and put in some new brushes.
What are part numbers that I need to pick up?

OK...I ask that you bear with me while I explain my question/issue.
I bought a used 2006 F350 Super Duty diesel last October (Oct 2015) and it has about 124,500 miles on it now. Last week, the power cut out as I was driving home from running an errand. Jumped it and got it back to the house. Suspected the alternator as both batteries tested low (according to AutoZone). Purchased the 110amp alternator and after a few days...I was able to get the alternator installed. AutoZone charged the batteries back up.
Today, I was able to start the truck and drive it around the block in order to make sure everyone was okay - before I took it out on the streets. Got back to the driveway....ABS light comes on, radio shuts off, odometer light goes off, etc. I shut the engine off and let it sit for a minute. Try to start it back up...and nothing happens. Ended up disconnecting both batteries while I ponder the root cause of the issue.
Is it possible the 110amp alternator is not strong enough to handle the power requirements (and that's why the dashboard lights went out)? To the best of my knowledge, there's only 1 alternator. The only "extra" that's installed is the tow/haul package (which I haven't used yet). According to the Ford Parts web site - after I enter the VIN for my truck - the results show a 110amp alternator (heavy duty alternator).
Would exchanging the 110amp for the 140amp be the most logical place to start? Or is there something I missed as a replaced the alternator?

After 2yrs and 1mo, my DC power 270XP amp died. I put the almost 10 yr old factory alt back on and everything is good again, except for the glaring fact that I have a dead alternator. It is a month beyond warranty (of course).
Truck has been running great. Oil cooler, EGR bulletproof cooler, STC done in Dec at Ford due to high deltas. I have a small stereo - one 12" sub woofer, otherwise nothing that really stresses the electrical system. I did the "big three" with 1/0 copper - cost a fortune, saw no difference - but that could have been an issue for the alt.
I left a message today with etch support but did not get a call back. I hope they make good on this - I waited almost 4 mo's to get this thing and it was supposed to outlast my truck.

i just had my 190amp DC Power Alternator just died. It was about 4 yrs old. I ordered a new Bosh AL7606 I know it's 140amp but it was half the price and in stock on amazon also lifetime warranty. I'm thinking of moving the pulley from the DC Power to the Bosh. Any thoughts? I went to the DCPower website but they were sold out and twice the price. I might just get the DC Revuilt as a spare?

I have a 2001 F350, 7.3. My service engine light came on and immediately the truck started to run rough and lose some power. I've checked the under the cover connections and they were both connected, I replaced the cam position sensor and I still have the same problem. The worse part of the hold thing is that there are no codes stored so I'm flying bind. Where to go next.

The problem occurs when you hit bumps while braking, or if you get on the brakes to hard. It seems like the brakes lose pressure entirely and the pedal goes to the floor. It kicks back in when the ground smooths out, or if you are braking hard it slowly grabs again. At first i thought it was sliding, but it definitely is not. The truck appeared to be equipped with abs but the previous owner seems to have cut the abs wire/sensor at the hub. Another thought i had is maybe the brakes need to be bled and have fresh fluid put in them, I have not tried this yet (Plan to this weekend along with a dozen other things). Its rather scary when it happens. but i didnt think much of it until i nearly rear ended someone..with my younger brother in the car. Now i need to fix this asap.

How to figure out what caused my rear seats to lose heat?
No heat, no illumination on the buttons
Fuse looks good

A few weeks ago, the TPMS light (and the start-up warning) came on. I checked all the tire pressures and they were fine. I checked the spare tire, and sure enough, it was low and I fixed it. However, the TPMS warning still comes on every time I start the truck. It's not the flashing icon that indicates a problem with the system, it's just the steady "low tire" yellow light.
Not only is it annoying, but it won't indicate if there really is a low tire.
I know the old TPMS sensors only worked when the tire was rolling. If the modern sensors work that way, could it be the spare tire monitor? Is there anyway to know which sensor is sending the warning? I know the dealer is going to charge me an arm and a leg to look at this, so I'd like to know what's going on before I take it in.

I have a 2006 F350 Crew Cab with the 6.0. It is used primarily for towing a fairly heavy 5th wheel RV. I find that the accelerator pedal pressure is much higher than any previous vehicle I have ever owned. The problem is magnified by the fact that I have a previous ankle injury that makes it very uncomfortable to have to press on the accelerator so hard for long periods of time.
I try to use the cruise, which sometimes works on flat ground, but the shift point at my desired cruising speed is such that the slightest grade will make it downshift. With the cruise off and my foot kept at a constant pressure, the truck pulls up the slight grades just fine with no significant loss of speed and no downshifting.
Is there any way to lighten the pressure it take to push down the accelerator? I know it is actually moving a throttle position sensor, but is there also a pedal return spring here that is too stiff for me?

For the last couple months when not towing I take the front tires to 65 psi and the rears to 50 psi. It gives me the warning light which I click OK to every time I start it. This weekend I put everything back to 80 psi getting ready to tow and I can't get the warning light to go out anymore. I double checked my pressure to make sure everything was OK and it was. I will be taking it in unless someone knows a reset or something else to check out before I do.

Not another dumb "water in fuel" post... I had the warning light come on the other day, so I got under to drain the filter. Not much water came out before the diesel, but I let some diesel drain anyway to be sure. What was strange though, was the electrical connection was off. I must have hit something somehow and pulled it out? What I'm wondering, because of the little water that came out of the filter, would the light have come on from the plug getting pulled out?

I have a 2003 F350 6.0. I had a flickering Battery lt on the dash last week so I replaced the Alternator. People recommended I upgrade to the 2005 140 amp alt from my stock 110. I have a single alt system. So I did, today it died on way to work. Batteries were drained. Had new alt checked and its fine. So All I have is a wiring diagram from 99-2002 but it shows the plug on the alt with 2 wires, Lt grn/red from switched ign and Org/Lt Blu which goes to batteries. Org/Lt blu has 12v but Lt green/Red has nothing with ign sw on. I did check fuse 45 in Central J box and have power there. I did notice I have no battery Lt on dash when you turn Ign sw on, and never got the Lt this morning when it died. What Im confused about is do I have a PCM? my diagrams that only go up to 2002 model show it for a 2 alt sys but not for a single alt. I should have power on Lt Grn/red with ign sw on correct? Everyone said 2005 alt was plug and play, the elec connector is now pointed down, where it was pointed up on the orig alt, look to be wired the same.

I've got an 01 7.3 lariat 4x4 with an 03 7.3 engine in it (long story behind that) but basically I noticed one day I had a hissing underneath my dash and my brake pedal was a little spongy but my truck stopped, well before I could get it to a shop and checked out it went bad. Coming up to a stop sign and as normal hit my brakes and right before it came to a complete stop the pedal shot to the floor and I lost power steering as well as brakes and went rolling out in the road and almost got hit. So it's been parked ever since and I have changed the hydroboost, the power steering pump twice, flushed everything and bled everything and still nothing, can't even find any leaks. What to even replace now or whether to just take it to a shop and spend another small fortune.
