Ford 6.0L Power Stroke Diesel :: 2006 F250 - Alternator Rebuild - Charge Light On Intermittently?
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?
Ford 6.0L Power Stroke Diesel :: Batteries Get Discharged To A Certain Point / Alternator Not Charging
I ve been noticing that the alternator isn't charging correctly, or at least it seems like it. We drive short trips sometimes two times a day, a mile or less. One day, night actually, I noticed it started to not turn over with it's usual enthusiastic sound. When the batteries get discharged to a certain point, the voltage at idle will be less than 12 volts. If I rev the engine for a bit, the volts jump up, but at idle it drops back to 12 or below. Seems to me that it should be at least 12v or above if the batteries are discharged, and more towards 12.5ishV if the batteries are fully charged.
After I put it on a 6A charger overnight, the voltage upon starting is above 12, sometimes over 13. But if the batteries start to dwindle down from short trips, the voltage drops to 12 or below at idle.
I did install the smaller pulley a few years back, and that worked massively. I couldn't get 12V at idle before installing the smaller pulley. But now it seems like I'm back to that same situation before installing the smaller pulley.
So, I m guessing that a alternator bench test is in my future? The batteries are fairly new, tho they have been down to nothing at least twice from boneheaded moves by yours truely!
And, I'm speculating that this charging situation contributed to the recent FICM replacement that I went thru.
Prius (2010-12) :: How To Fully Charge Batteries While Driving On Highway

98 Ranger 4.0..4WD ex CabXLT Automatic..started the engine yesterday and my charge light came on and stayed on. Checked the guage and it showed no charging and then slowly began to charge and the light went out. If I rev the engine above 2,000RPM's the charge needle starts to drop but if I keep RPM's below 2,000 charging is okay. Is this the sign of a failing alternator? The belt only has about 20,000 miles on it and tension seems oksy

2000 f350 7.3 .. I'm having a horrible time trying to figure out why my truck is draining down the batteries. I can charge my batteries over night and put hem in and the truck will run for a few hours but then it dies completely. The alternator seems to be running really hot afterward like it is being over worked. I put in 2 different alternators and 2 new batteries and it didn't fix the issue.
I then put in a new starter relay. Still having the same issue. I believe I have a short because I tested for it but am unable to locate the short. I heard if you over work the bushings in the starter they can ground out on the casing which will cause something similar to this to happen. I work in ND and had to cold start it in - temperatures the morning this all began. I purchased a new starter but don't want to put it in if that is not the issue.
Ford Excursion :: ABS Light On After Batteries Replaced
Today I had to replace both batteries and now my ABS light is on. Before replacing the batteries I was installing a XM satellite system and my dash face plate was removed to make installation easier. After putting everything back together and connecting the new batteries the light is on. Tomorrow I will see if any codes come up using my Scangauge II otherwise I'll have to go to the parts store to have them pulled.
This is on an 04 Ex, Limited, 4x4, 6.0 PSD......

View 14 RepliesGolf IV / Jetta IV :: 1999 Mk4 VR6 - Battery Will Not Charge And Alternator Seems To Be Nonfunctional
I am having a really curious issue with the charging system on my 1999 Golf VR6. The battery will not charge and the alternator seems to be nonfunctional. While running the voltage at the battery starts normal but drops until the engine dies within 20 minutes. Over the last two days I have replaced the alternator, battery, and the battery grounding cable with no change in behavior. The exciter wire on the alternator is showing 9 volts when the vehicle is running and 0 when it is off. There is 1.6 ohms of resistance between the B+ terminal on the battery and the respective terminal on the alternator. There is 0.3 ohms of resistance between the B- battery terminal and the case of the alternator. My task for tomorrow is to trace the exciter wire back to the cluster and try to troubleshoot it there.
View 9 RepliesCamry :: Charge Wire Touched Alternator And Sparked Now Car Doesn't Start
So the charge wire (wire held on by 10mm nut) on the alternator accidentally touched the body of the alternator and it sparked. My idiot-self forgot to disconnect the negative from the battery. I hooked everything back up and now my car doesn't start.
It doesn't crank and it doesn't even make a buzzing noise or anything. The radio doesn't work, the power windows don't work. The power locks DO work, the dome light, headlights, and footwell lights also work and my amps do receive power.
There are some burn marks on my alternator from where the charge wire touched, but could that affect how the car doesn't even crank? Does the alternator have anything to do with starting the car?
Corolla / Matrix 2009-13 :: Alternator Is Shot, Battery Won't Hold A Charge Either
I am pretty sure that my Denso alternator is shot. My 2010 Corolla S will not start, battery won't hold a charge either. I pop started my vehicle around 10:30am today and drove 30 minute north on the 101. My car appeared to have no issue maintaining power. I rode my bicycle around for about an hour and then tried to start my car. Nothing. Tried to pop start the vehicle twice...still nothing.
The battery has about 40k on it. Car has 121k. So I am guessing it is my alternator.
Like I said the current alternator is made by Denso. I would like to buy a higher quality alternator with maybe a little more cranking amps.
I also am planning on purchasing a Optima battery, should I stick with a yellow top or a redtop. I have some aftermarket audio, only amp is in the Pioneer head-unit (avh p440bt), which is connected to aftermarket 6x9s and components (JL Audio c2-690tx and JL Audio C5-650).

View 2 RepliesCamry :: Batteries Replaced Several Times, Keeps Failing
My wife drives a 2005 Solara 4 cylinder 2AZ-FE. Over the past few years, it has been going through batteries about every year and a half. The batteries have all failed on the load test.
So far, I've removed the alternator and taken it in to get it bench tested, tested fine. I had the full charging system check with the machine, starter tested fine, alternator volts were fine, only problem was the CCA load test (for which the battery was replaced under warranty). I tested for parasitic battery drain several times, got some drain for awhile after car is powered off, but it eventually falls to zero. I checked for voltage drop across the wiring, visually inspected the wiring to the starter, alternator, etc. and made sure the ground connections were tight from the battery to the frame and engine. Everything looked good.
The only thing I can come up with is that the most recent battery boiled over a bit at one point in time because there was evidence of acid spillage. Also, once (and only once), my wife noticed her lights flickering while her car was idling for awhile during a cold morning. These two things lead me to think it must be the alternator (voltage regulator), but neither the bench test nor anytime I test it at home reveals any issue.
Maybe it's an intermittent problem from vibration, etc. I just hate to plunk down the cash for a new alternator if that isn't the issue.

I have a 2001 Prius and I replaced the modules with Gen II. It ran fine for awhile then the red triangle came back and the ICE would have a high revving sound and the brake warning light would come on. I can make this issue go away but pulling over and turning off the car and turning it on again. I pulled codes 3000 and 3006 and understand the problem may be uneven battery module levels. I have been driving it in an attempt to see the the modules will self level. An earlier dealer diagnosis also recommended a system main relay replacement which I did not do. It drives fine most of the time but maybe once a week the high revving issue comes back.
