My battery indicator light is doing weird stuff. I have a secondary volt gauge that shows good voltage throughout. Checked posts and connections tight. At idle the warning light is off. Under slow acceleration it starts to flash with the frequency increasing with greater acceleration until it finally goes solid with normal acceleration and highway speeds.
View 3 Replies2005 Excursion Limited 4x4. Will not go into 4 wheel drive. At initial key on the 4x4 indicator light comes on briefly. Tried manually locking the hubs, no 4x4. Tried swapping the underhood relays around, no 4x4.
Should I be looking for voltage at the transfer case 4x4 motor to determine if it is faulty when turning the in cab switch to 4x4? I'm thinking that would tell me the transfer case motor is shot, I think.
I just bought my 2002 Excursion about a month ago, and the cruise control doesn't work. When I'm driving, I press "ON", then "SET", the CC indicator light comes on, but when I take my foot off the gas, it doesn't maintain speed.
I've done the self test, and all the lights blink once. Just to be sure, I've replaced the CC switch on the master cylinder, and the Brake switch mounted above the brake pedal. Still no joy.
The manual just says it's a charging system problem.
View 8 RepliesIn 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?
Just bought my first F150. 1998 XLT 4.6l automatic. 126K miles, looks like it was mostly garage kept. All power, A/C, etc.
Picked it up this evening, drove it home after dark. About a 30 mile mostly highway speed drive. Everything went fine, no problems, no hiccups......Until I turned on my last street, about a half mile from home. The battery indicator light on the dash started blinking intermittently. I didn't notice anything else, just the red battery shaped light blinking.
What would cause this, what should I check? I don't want a big problem when I haven't even transferred the title yet!
98 Ford Expedition 4.6L, 198K Miles, New Battery, Alternator replaced, but battery light still on and after a minute charge indicator drop until left indicating zero, temp gauge on top while temperature motor is cold, gas gauge drop, when lights are turned on oil light turn on also check engine both for a few of seconds.
View 2 RepliesI just did a brake job on my 2002 2.7l and 10 minutes after driving both the e brake and battery indicator light came on not the abs. It is not throwing any dtc codes also. Did I do something wrong or is it a coincidence meaning my alternator is crapping out? I replaced all pads and front rotors and sucked out some dirty fluid and added clean fluid. It brakes properly and I do not believe I got air in the system.
View 4 Repliesi have a 2000 ex,6.8 4x4.every now and then the dome light stays on.theres also a problem where theres a buzzing sound coming under dash while driving and makes the dome light flicker.these are seprate problems.lol.when the buzzing sound is present ,it stops when i open the door,running or not.but starts up again when i close it,even happens occasionaly when ignition is off and no key in ignition.electrical problems are my worst night mare!!!!!!!! My battery is dead in the morning when this is happening .oh yea,and the o.d.light flashes occasionaly as well.im totally lost.
View 6 RepliesI just noticed this happening the other day. Sometimes the battery light will come on for a second then go off. It seems to happen when I accelerate. I've watched the battery gauge and it never moves when the light comes on. I have a digital voltmeter that plugs into the cigarette lighter and it reads 14.2 volts constantly, even when the light is on. So what could cause the battery light to go on besides a drop in voltage?
View 9 RepliesCame on intermittently other day, got it home then did not start. Charged for a bit, it started on the charger then off the charger a few times I assumed out was the alternator just replaced it. Battery light now on continually, hope I didn't destroy two batteries driving out for 20 mom after light first illuminated, they already to be only one year old. In addition to the ABS light now and the brakes feel unboosted? Hopefully fuses popped?

View 9 RepliesSo my dummy light came on the other day, I went ahead and pulled the alternator and had it tested at advanced. It tested bad so I replaced it not my battery light comes on and off randomly. I have a edge tuner on my truck and my voltage reading on there is different after each start up. Sometimes it runs 12.1-12.2 other times it reads in the 14's I have checked with a multimeter also and got the same readings +-.1 or 2.
My dummy light keeps coming back on randomly, I had to replace the alternator connector because I broke it by accident. I also traced the wires as far as I could to check for brakes in the wire and found none with out proper time to pull all the wire loom off. What is the cause I know I could probably use cables soon as my terminals look a bit rough but are clean. Seems to be some really weak flimsy metal. Which fuse to check as my 2002 ex 7.3 only has the inside fuse block and I can't find much online about it.
As I'm driving along, I get the battery light coming for a few minutes then going out. Is this a sign my alternator is on the fritz?
View 7 RepliesSo I get in my X today and she fires right up as usual... Then the battery light started blinking then stayed on... Then I hear a click and all my stock gauges go out my window and lock switches don't work and my radio doesn't work... Battery light stays on and all signals work as do the mirrors and everything else... I turn the truck off then back on it all comes back on.. 15-20 seconds later I hear the click and all the same stuff is off again.... No seemingly applicable fuses are blown... And the behavior is repeatable...

My battery light is coming on intermittently but the truck seems to be running fine need to know how to test it to make sure that is the problem.
View 9 Replies2000 Ford Excursion XLT 4x4 V10 ... Part store shows I need a 3G alternator ... Current alternator put on by PO in 2013/14 s a Duralast DL7764 from Autozone. Tag is still on it.
My battery light is coming on for a few seconds and going off for several hours before it comes on again. Connections are good....crappy Autozone alternators.
But for some reason my motor has a 6G alternator. All parts stores say I need a 3G. Did Ford put 6G'S in all excursions, or do I have a 2004+ motor in my 2000 Ex? Or will a 6G fit where a 3G is supposed to be? All connections look factory including electrical hook ups.
The Battery Light flashes on 2002 excursion 7.3l. I have been having a problem for several months, one of the batteries ended up being shot, alternator checks out. Problem is there is nor rhyme or reason as to when or if the light will flash, it is not consistent with a shorted wire that is bouncing around and grounding out.
View 14 RepliesI have been having an intermittent door unlock switch failure... The driver side and passenger side unlock doesn't work but the lock does... It has been intermittent, but now seems consistently not working... This is now accompanied by a flashing battery light on the dash, which I've never seen before....as well, the dome lights have stopped working, could be bulbs, haven't checked, but i replaced them within a year ago...
I guess my question is.... Would a flashing battery light be connected to switch not working? Is it likely to be the module since both passenger and driver side unlock function failed at the same time? I doubt both actuators would go at the same time...The other odd thing to tag on to this is a month ago my fuel gauge went dead... I keep wondering if there is a common connection....
I have a 2000 Ford Excursion XLT 2WD with just over 155,000 miles on it, for awhile now My battery light has been on and off or it'll flicker and some times it will even stay solid. I checked the batteries and the alternator a while ago and got good readings from them. I just thought it was a code that never got reset. Well this morning I was driving it and I noticed that when I brought the RPMs over 3,000 the battery gauge would go up to 18 volts and the battery stayed on until the RPMs went back down past 3,000. It did this all morning until I got home and just for kicks I put it in park and revved the engine up to 3,000 RPMs, when I did nothing happened. I tried looking online for an answer and I called a few mechanic shops who all said it was my alternator. I want to make sure that it is in fact the alternator....
