What this part it is? It sits over the alternator on the driver side and looks like a couple vacuum hoses plug into it. Mine is making a very loud buzzing noise.
View 8 Replies2003 6.0 auto KR. Ign turns on, dash comes on like normal, windows & lights all work, vacumm pump works.. Thats it. Starter turns well if I hotwire it. Other then that she's dead. No buzz on inj when ign is on. OBD port has the power on blue/white wire but rest have none. Scanner says can't connect. Fuel pump doesn't run. Starter doesn't crank. All fuses have been checked.
Checked with test light on all the engine related fuses and they all light up. Relays have all been switched around. Tried another used PCM to test. Unplugged fan, ebp, map, maf. My brain is going on overload trying to get all these electrical issues fixed. I much prefer a HPO leak or inj going bad, that I know how to tackle. I hate electrical.
My nephew has a 2004 F350 that will crank but will not start. It will build oil pressure on the gauge. There is no injector buzz and no communication through OBD2 port. Is the PCM dead?
View 10 RepliesOK...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?
View 14 RepliesI 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.

View 7 RepliesI 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 found out by accident that my vacuum pump is now running all the time. It's not the gray line to the heater valve and it's not the vacuum canister as I already checked the easy stuff. I need some direction where to start looking under the dash as I have never been under that part of my truck. Any common issues or where to look?
More information: The pump only runs all the time when the HVAC control is set to OFF or MAX AC.
Haven't found any other useful info on this, but local dealer says that's where my truck is leaking oil from, and since it's considered brakes not powertrain the repair won't be covered under warranty ...
Backstory goes : dropped my truck off at local dealer Thursday to repair an oil leak from near front main seal area of the engine discovered while inspecting to initiate a bumper-to-bumper warranty through Ford ESP- their platinum warranty. I figured with all the electronic widgets and non-powertrain stuffs on this beast I wouldn't mind paying for 3yrs/36k miles of trouble-free motoring, y'know?
Apparently it's the O-ring on the brake vacuum pump that's allowing engine oil to leak. I can't even find this thing, just looking for some further explanation. I'm keeping an open mind so far, I don't suspect the dealer's just trying to get one over on me, just trying to be good and educated before I go plunk down for the repair.
When I park over night while in 4x4, the next morning my hubs are disengaged and I have to manually lock them. There is an apparent slow/slight leak in the vacuum system. What would be the usual suspect, so I can start at that point?
View 3 RepliesI 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.

Just changed my alternator, that was the easy part apparently...............
Cant get fan belt back on? My pulleys don't look the same as the picture under the hood. I can see a idler on passengers side down low, but cant seem to make it move to give me some slack.
What kind of tool to use on idler to get slack?
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.
I am having a charging system issue. The alternator is making barley over 12 volts. With KOEO the battery light on the instrument cluster does not come on. I have already replaced both batteries and the alternator -before i noticed the battery light is not coming on.
View 2 RepliesI have a 2004 E350 6.0 with a bad vacuum pump. I tried looking on Youtube for a video on replacing the pump but no luck. Looking for a video or instructions on replacing the pump? It looks fairly easy but you need to be a snake to gain access to the pump bolts.
View 9 RepliesWe'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?
View 4 RepliesSo 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 .
View 14 RepliesBrake booster failures on 2011 and newer F-250's? I purchased a 2011 last august and the mechanic at the dealer I purchased the truck from stated that he had replaced the vacuum pump, vacuum brake booster and brake master cylinder on the truck just before I bought it as they were bad. Since then I have had two factory Ford vacuum Boosters fail on me. That makes at least three new factory Ford booster assemblies in this truck within the last year. What could be causing the problem? The truck is out of warranty and I am at a loss as to what could be causing them problem. Too much vacuum? Luckily the last two boosters have failed while sitting in a drive through and at a stop light, otherwise I may have had trouble stopping.
View 3 RepliesMy 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?
