Ford - F150 :: 1999 - Battery Light Is Staying On
Nov 23, 2014
I have a 1999 F-150 4.6L V-8, and the battery light is staying on. Something is draining the battery. I have taken it to Auto Zone, and they tested the battery (brand new), starter, and alternator - all show good. The only error they can register is "C1226 brake light lamp short." What could be causing this? I had to get jump started at a gas station 2 nights ago. I have checked the alternator fuse, and it is ok. Could the wiring be bad somewhere?

I have a 1999 Ford F150 6 cyl. 4.2, 2 WD with 160,000 miles. Replaced the battery May 2010.
Today battery light came on. Battery gauge did not look like it was discharging. Had battery checked they said it was a little low but OK. Then they continued test and tried to check alternator, test stopped and they said something wrong with alternator most likely.
I took alternator out and had it bench tested. They said it was OK, putting out 98 amp on 95 amp alternator. They said check wires, grounds, harness, connections. Checked connections and wires as much as possible, reinstalled alternator, light still on.
Have not checked fuses yet. Was told to start vehicle, disconnect positive battery cable and if engine continued to run alternator was good, if cut off alternator was bad and to replace. Should I try this and is it true?
What is the part on the fire wall that is between the alternator and the battery that the wire connection runs through? Can it be bench tested/checked?

Over the past few days the battery light has been flickering and at times staying on. In using the gauge cluster diagnostics, I am getting 12.4 engine off and 13.8 - 14.0 with the engine running.
Even when I'm driving with the battery warning light on I still get a consistent 13.8 - 14.0 (and I do have the headlights on, the A/C running, radio, etc).
Kind of scratching my head on this issue since it appears the alternator and battery are working correctly.

When the battery light on my F-150 came on (about 100,00), the dealer put on a new alternator. This has now been done 3 times in the last year, and the battery light still comes on intermittently. They have no ideas about what to do.

I started having an issue with my battery light coming on and staying on so everyone told me change the alternator. So i did. 4 days later the battery light came back on and now i have it in the shop, alternator check came out good, battery check came out good and starter check came out good.
I haven't had any issues with the car before now, i have made several long trips, bought it brand new and have 69,000 miles on it. I love my car, but I am scared to find out what it's going to cost to fix it.

Battery warning light came on a couple of times when driving to work in my 2000 F-150. I had thought that the instrument lights had looked dim for a couple of days. The warning light was only when the truck was idling and the warning went off as the truck was moving.

The alternator on my wifes '07 Santa Fe (2.2 CRDI) broke down when one of the internal diodes gave up last week. The battery warning light came on when she was driving to work. Since then the Alternator has been rebuilt and refitted, and the battery fully charged. The car now runs fine and the Alternator is putting out around 14.6v so charging the battery OK. The only problem is the warning light is still on. How to get it to turn off ?

Start out, drive about 20 minutes, get on the Interstate and the battery light comes on 2008 F 150 5.4L 4X4 - 57K miles..... get to my destination, went about 20 miles, turn around to come home, without turning the truck off because of the battery light being on and I notice the charging gauge drifting down to the left, get back on the Interstate and the wipers are slowing down and lights on the dash are dimming.....go around 15 more minutes I lose all lights on dash, wipers, defroster everything, charging gauge is now pegged all the way down to the left and the truck is starting to act up running like crap so I barely make it off the Interstate and call a flatbed, I guess I was about an hour into the trip ..... battery is only about a year old and it started fine that morning and the day before when it was about 12 degrees ...... dealership had the truck, just gave me a call and said they can't find anything ?? ..... never a days problem since I bought it new in late 07' ....

Problem with my 2006 F150 5.4 4x4... Voltmeter spikes, battery light comes on, grinding noise as 4x4 engages on its own then everything returns to normal after about 60 seconds. Took to Ford who replaced the alternator and battery, still doing it so they replaced the alternator again...they checked the wiring and replaced some other misc parts and don't know what the problem is. The problem occurs once every few days, after only a few minutes or after a few hours, completely random.

I just replaced the rear calipers on my wife's Taurus wagon (old ones were siexed) and bled the brakes as normal, but now the brake warning light is on and staying on. At first I thought it was the parking break, but it seems to work fine, (Tried setting the parking break while in motion and the car slowed quickly.) Its the first time I have changed the calipers on a car. When bleeding I did so until there were no more bubbles pulling about 8 oz from each side. The reservoir did get low but I don't think it emptied. Is it possible that I went too far and now have air in the master cylinder? How would I correct this?

My neighbor's kids truck battery drains from full charge to "no start" in 1-2 days. 1999 Ford F-150 w/ 4.6L engine. He has already.....
1) Replaced the Battery.
2) Replaced the GEM module.
3) Replaced the Turn Signal Relay.
He did all this before I looked at it....
I checked the following....
1) Truck off, doors closed, hood open... Amp meter shows 3.6 amp draw. When 1st hooked up, shows 4.2 amps... after a while drops to 3.6.
2) To isolate the draw, we pulled fuses while checking current draw at battery.
a) Under Dash fuse Panel. (Yes, with door closed) We remove fuse #15 "stop lamp switch, speed control, brake shift interlock, ABS, PCM,GEM, RABS test connector". (Really... couldn't be more stuff?)
b)Under the hood is another fuse box (drivers side). We remove Fuse #103. "Junction Block Battery Feed".
3) Found that if we remove the #15 fuse under the dash with the door opens, all interior lights flash on/off at about 1 second intervals... weird.
4) Again, another weird one... with the fuse #15 removed and door closed, the "ABS" indicator and some other indicators and dash lights are staying partially lit... not fully lit.
5) The only "aftermarket" stuff i can see is a dealer installed trailer brake system. Wiring looks professional and disconnecting it does not remove the amperage drain.
I'm hoping that one of you wizards will give me the "slam dunk"... if this happens, it must be that. Can I be so lucky? And, yes. I have my own '06 F-150 that i absolutely love. 6-cyl., manual trans, stripped down without even power door locks... my kinda technology.

So 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.

Just 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.

Truck '02 F250 SuperCab - I was having an issue with the door ajar light staying on and the radio not shutting off upon exiting the truck. After having no luck with the WD-40 fix, I replaced the door switch sensor on the driver's side door and disconnected the negative battery cable for a few minutes (maybe 5-10).
Problem solved or so I thought...a few days later (approximately 5) the door ajar light came back on and the radio did not shut off. I disconnected the negative cable and sure enough that fixed it...again The problem is that every few days I have to go thru this. I'm not sure if it's related or not, but the CD player has started giving me "error reading disc" on even brand new CD's.

I have a 2012 f250 been in the shop 4 times for the traction control light just coming on randomly and staying on. they have flashed it changed something in the steering column forgot name of that and changed some sensors out. still does it. I think its a bad connection or bare wire is what I keep saying to them cause it only does it on rough roads and when its wet.
