Had a bad alternator, changed it, and now the battery lite stays on all the time..Changed the alternator again with a known good one, and the light is still on all the time..
View 14 RepliesAlternator locked up in a parking lot. Replaced it and had to replace pigtail due to a loose wire in the harness. Now battery light comes on intermittently. New alternator is doing fine producing anywhere from 13.9v to. 14.4v. No output voltage correlation to battery light at all. The belt is still in great shape so I don't suspect slipping. Fortunately I caught the old one locking up almost immediately and had recently replaced the belt. Output voltage looks great. Are there any fuses for alternator?
Only thing I can think of that I did...when splicing in the pigtail that connects to the alternator, I briefly grounded whatever wire in the pigtail is hot. Was just a split second, but enough to see a spark and maybe enough to blow a fuse? I've seen people reference an "under hood" fuse box, but I don't seem to have one. My truck is a 2002 CC with just over 100k on the clock.
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?
View 14 RepliesSo my red door open light started staying on. Along with all the lights associated with the doors being opened. The lights don't always come on, but the dash lights stays. As a quick fix I just popped the bulbs out and went on my way. Tried lubing the doors. That didn't work. I started noticing it seemed to be related to when I was slowing down or turning.
I thought maybe it's my passenger leaning on the door around the turns. So I inspected all the doors, they latch fine and don't feel like they're open. Last night I was riding by myself, and I realized that it wasn't anyone leaning on the door. When I would slow down, at the same spot. I would hear a click and the lights by the doors would come on, as well as the light on the back of the cab over the bed.
It did it every time the whole way home. It was approx. 16-18 mph when it would click. It was the same spot each time but I couldn't really nail the exact speed and watch for deer. I originally thought I'd just replace the sensors in the doors, but idk if that'll work anymore since it seems to be affected by other factors.
Door ajar light stays on. Lights were staying on until they timed off but after two days they have returned to normal operation. Where the switch is located on the door frame, I can't seem to find it. 2002 ex psd.
View 12 RepliesJust bought a 2002 F-250 4x4 Off-Road Crew Cab 7.3L and the airbag light is staying on. I have found out after the fact that the truck has been previously involved in a front end collision. The damage was to the passenger side front. I turn the ignition on, the airbag light will come on solid (just like all the rest, with the exception of the 4x4 and 4x4 low) then go out. Then it flashes slowly 2x then 5x, then goes out for a bit then repeats a few times before staying on. This tells me I am getting a code of 25. I have searched with no luck to narrow this issue down. Everything mechanically works, cruise, horn, etc. The only thing I can find wrong is when I engage the 4-wheel drive (floor shifter) the indicator lights do not illuminate in the instrument cluster. Neither the 4x4 nor the 4x4 low. I am unfamiliar with this truck, so I don't know where to began searching. I cant afford to take it to a dealer and I have children in the truck quite often, so I would like to remedy this very quickly.
View 9 RepliesGot new batteries installed yesterday and found that the passenger side battery has a nearly broken positive terminal. Had to handle it very gently.
Don't want to replace the entire battery cable just to get the terminal. Using bolt-on replacement terminals? What did you go with and where can it be found?
Background: '01 Excursion 7.3 4WD, 264,xxx miles, batteries less than three years old, new alternator [URL] .... , using an Edge Insight for digital readings.
Problem: I replaced the alternator about three weeks ago, first week all normal. Second week alt/battery idiot light comes on, then to add more frustration it is consistently inconsistent in its reading.
The volts (upon starting) jump around 11.6 - 12.1 when first starting. The light comes on while accelerating and goes off during no throttle while cold.
After warm-up the light will come on intermittently even though the reading is 13.0>, but never during off throttle.
It seems to do this more when cold but it does not completely stop when it's warm. Yes, I don't think that should be a factor but it is a reality .
I'm thinking it's a bad voltage regulator.
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.
View 11 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 RepliesI've got a light burned out on my dashboard. No big deal (it still gets some light from an adjacent bulb) but just out of curiosity: How big a nightmare would it be to replace a lightbulb in the dash of a 2001 F-250 XL?
Do you have to pull the motor/trans and lift the cab off the frame like I've been told you need to do to replace a heater core? Local mechanics laughed at that job and told me to get some stop leak...
Battery light came on about two months ago it would flicker. So i had Auto zone check it out batteries were good just needed a charge. so i charged them no fix so i said alright ill do the Alternator did that and then beginning of this week it happened again so checked it went back got a replacement alternator since they said it tested bad. Put the new one on and didnt change anything. Check my batteries they were reading 10v each. I charged them and they wouldn't hold a charge. so i replacement both batteries.
So i have a new alternator and two new batteries light is still on. Contacted my tech (whose a friend) he said to check the wiring going to the alt he said both wires should read 12v on constant other when the key is turned on. Tested the constant it has 12v other reads 6-8v with key on.
He also said sometimes the wiring on the X pipe can short the alternator? i unhooked all the wiring from the Xpipe nothing changed per battery light being on or off. So what should i do.?
Also my dash lights don't work but that's been like that for awhile (bulbs are all good).. Forgot to mention sometimes the light goes off but seems to stay on 90% of the time.
I have an odd issue, 2003 7.3L f250 ... My battery light flickers on and off, I had the alternator tested at a alt rebuild sale place here locally, I don't always trust the auto zone techs, also had the batteries tested at interstate batteries. both batteries good, alternator good.
I think my connector is bad on my alt, not the one that goes to the battery, output is 13.8 to 14.1 btw......there is another connector that is a PITA to get off. I think it is bad, I played with it and applied some dielectric grease had the light go out when I wiggled it.
Can just the connector be replaced?
So was replacing my power steering pump get all done and my headlights start flickering and then stay on the switch is off it does have DRL on it but they have been unplugged for about 10 years what do I need to check
View 3 RepliesI have a 2001 F250 Crew Cab with Powerstroke. The dash lights are starting to go out one at a time. How do I get to and replace the bulbs?
View 14 RepliesExternal LED hooked to GPR
I have gone through around 7 alternators in the past 18 months. I currently have a new NAPA alt and new interstate batteries. Today I noticed that my battery light is on again. I also noticed that my yellow squiggly Glow Plug inrush dash light was on at the same time. However, I do not believe that my GPR was active BECAUSE... I have an external red LED that lights up any time my GPR is active. When my GP dash light came on my external light was off. I had just driven 26 miles and my truck is warm and the outside temp is around 70 Fahrenheit.
My battery light come on this morning. The volt meter is sitting right where it always has though. I noticed that the battery light is kind of pulsating with rpm and at idle its very very dim.
E99 F-250 PSD ....
Where should I start?
In the last couple of days my battery light comes on after about 30 mins of steady driving. I have no starting issues as of late. Batteries have been tested under load and checked out okay. Alternator is a few months old. Other than the battery light coming on there no other
problems, yet. Is my alternator over charging? A couple of month ago my truck would shut off when I turned a/c or heater on in the mornings. My alternator was over charging. After I replaced it I had no more problems. Could any of this be related to the life time led bulbs that I'm using?
I have a 99 f350 7.3l 4x4 and my battery light flickers randomly. I have checked the alternator and both battery's. All brand new and seems to be ok. They only are getting a charge when the battery light is flickering. I put both new batteries in on Thursday and on Sunday I needed a jump at the store.
View 7 RepliesBit of a confusing one as of late. Doesn't happen every time I drive, maybe 50% of the time. When I start the truck up, torque pro reads voltage at 13.9-14.1 consistent. After 30 minutes it usually drops to around 13.7/13.8. Sometimes, battery light comes on, voltage doesn't drop. I can drive the truck, park it, turn it off, restart, no side effects.
I notice if I stop, turn off the truck, and restart it, torq pro will begin to read a voltage of 12.8.13.0. Sometimes it won't budge for an hour, sometimes it climbs right back up to 13.8, sometimes the battery light goes off, sometimes it stays on.
Alternator was replaced a month ago, both batteries replaced a week ago, all terminals cleaned and secured at the time of replacement. Truck behaves perfectly normal, I'm almost at the point of putting a piece of tape over the light and ignoring it, but was curious before I go that route.
