Ford Wiring/Electrical :: 2005 2WD - Battery Light Came On

2005 Ranger XL 2.3L 5 speed 2WD 305,000 miles. Alternator has about 100,000 miles on it.

Battery light came on about 0400 and 50 miles into my daily 90 mile drive to work, made it to work. After the truck cooled down for 3 hours and I got time I checked the battery voltage 12.6VDC and started the engine and the system is charging at 14.2VDC with no battery light on (battery light out when cold). Serpentine belt looks good, dry weather.

Other than alternator nearing end of life and being warm is there anything else that may cause battery light to come on.

Ford Wiring/Electrical :: 1997 F250 HD Manual Trans - Cruise Control Inopertive

1997 F250 HD 7.3L It is a May build so is mainly 1996 parts. Came from the factory with auto transmission but PO did manual swap. Truck had factory cruise control but never worked after the swap. I found clutch safety switch missing so installed that and now it works as far as truck only starting with clutch in and other pins ohm good but it didn't fix the no cruise issue. All the diagrams I can find are wrong so I am stumped.

Horn works and steering wheel brushes appear to be functional.
Brake switch has 12V in and out so I think it is ok.
Brake switch on master cylinder has power in and out so I believe it is ok.
All brake lights work since I read that diagrams don't show it but they are somehow tied into the cruise.

I believe the issue is in the clutch safety switch (CPPS) wiring as I only have power on one wire however my colors don't match my Haynes or online diagrams. Also, no where can I find if this circuit runs on hot 12V or ground. Some wrong diagrams show hot 12V coming in on the light green wire from the brake switch but others show a hard ground on the red/Blu wire.

Most diagrams say I should have red/LtBlu, Red/LtGrn, LtGrn, Gray/Yellow. I actually have Red/Blue, White/Red, Tan/Blue, White/Brn. The White/Brn has power coming into the switch.

The connector for the automatic transmission column shifter is disconnected and the shifter was removed. I read that this needed to be jumpered to the tan/blue wire after a conversion on the CPPS but only on 2002 and up trucks so I don't think this affects me. That plug is for overdrive cancel.

Looking for a good diagram for a manual shift, diesel cruise control circuit that shows my color wires on the CPPS? I have had this truck 2 months and have fixed everything except this and will be making a long trip soon so cruise would be nice to have functional but I am stumped.

Ford Wiring/Electrical :: 2002 Ranger - Battery Light Comes On And Off

I have an 02 Ranger 4.0 4WD and I have been doing a lot of research to try and figure out why the battery light comes on and off. I was driving the other day down the highway and the battery light came on and voltage gauge dropped. Drive a little further and it goes off, go down hill light comes on, up hill it turns off. (The up and down hill part was probably just a coincidence!) ...

Next day I pulled the alternator and had it tested at O'Reillys and it passed no issues. Yesterday I was driving again the light comes on my way home from the store and stays on for about 3 miles til I got home. Turned my truck off, restarted it later, no light. Today I drove around for a while and about 45 minutes into my driving around the light comes back on and voltage gauge drops and after about a mile it turned off. I stopped by O'Reillys again to have them test the complete charging system and everything passed. On the way home, light comes on again!

So, question is, the battery light was not on when they tested, will that make a difference in the outcome of the tests? I'm guessing not??? Belt looks good, no bad connections that I have found, battery was good...what am I missing? Battery light is still on and voltage low when I start truck after 1.5 hours of being home. Also, I get no magnetism from the alternator when the battery light is on.

Ford Wiring/Electrical :: Battery Light Is On In The Dash / Overcharging?

The battery light is on in my dash. To test it I probed the car battery with a multimeter. Car off the battery reads 12.5 volts. With the car running and no headlights on, heater fan off, etc the meter reads 15-15.5volts. When I turn everything electrical I can think of on the meter reads 14-14.5volts. Is this normal or is the second scenario overcharging the battery? What else can I test that may be keeping the battery light on in the dash?

Ford Wiring/Electrical :: 1999 F150 - Battery Light Came On

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?

Ford Wiring/Electrical :: Battery Light Started Blinking Then Stayed On

So 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...

Ford Wiring/Electrical :: 1997 F250 - Dash Lights Flicker Off When Place The Transmission In Drive Position

I have a 1997 F250 that I am fixing up. The issue is this... The dash lights now flicker off when I place the transmission in Drive position. I can slightly move the slack in the gear selector and the lights come back on. When the transmission is in Park, the dash lights work correctly. Not sure why there is some type of switch to control the dash lights buried within the steering column?

Ford Wiring/Electrical :: 2004 F250 - Airbag Light Flashes And Stays On

I have a 2004 250 SD. Supercab. Took out the bench and replaced with captains or buckets, whatever you want to call them. Perfect fit. The new seats have their own seat belts built in to them. The old ones, were mounted to the floor and roof. Now the air bag light blinks for a fairly long time, then stays on! What? OK, So, what do I NOT know about this project? I did have to make the wires longer in order to reconnect the plugs. Not a problem, I am an electrician. Trouble shooting is ok, when you know where to start.

Ford Wiring/Electrical :: 2011 F250 - Reverse Light Wire Under The Hood?

I would like to hook up some auxiliary reverse lights, I want to use a relay. And activate the relay when I put my truck in reverse. I would like the relay to be in my custom relay/fuse box under my hood near my battery. I'm looking for a wire I can tap into, to use to active the relay as close to the battery as possible. Or at least a wire on the outside of the cab near the engine compartment. Maybe there's one coming from the tranny? I have a 2011 f250 super duty. XL, I think, its a very base model truck no power windows or locks, only fm/am radio, no NAV system, no remote unlock, no nothing, 2 wheel drive.

Electrical-wiring - Acura - Rl - Gauges - Starters :: 1997, Battery And Brake Lights Came On After Alternator Replaced

I got my Alternator replaced last week. Last night, I hit a very small bump, not even large enough to really cause me to slow down, and as soon as I did, my battery and brake lights came on. My RPM gauge also jumped around and eventually went to 0 until I stopped and put the car in park. (The bump might just be a coincidence who knows). So after all this happened, I turned off my car, tried to restart and got nothing. Sometimes I get a click, sometimes 2 clicks up to 4-6 consecutive clicks. Every few times I won't even get a click, just a slight attempt to start, then the car dies, then 2 seconds later all my lights and radio etc. come back on. My problem here is a few things:

1. I've been told it could be the starter. If it's the start, those dashboard lights shouldn't have came on right? just the STARTING portion of the car.
2. I've been told it could be the battery.

Well If i got my alternator tested and Advance said it was working, Why would my battery be dead? And if it WAS dead, wouldn't my lights have went dim or something else happen to the car?

Ford Wiring/Electrical :: 2006 F150 - Battery Light On / Voltmeter Spikes / Grinding Noise As 4x4 Engages

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.

Ford Wiring/Electrical :: 1971 F250 - When Right Turn Signal Activated The Left Brake Light Does Come On

I have a unique problem with my newly acquired 71 F250. The left brake does illuminate when the brake is pressed but when the right turn signal if activated the left brake light does come on. The left flasher light also does not work. All other rear ligh function are normal. I am assuming I have a short or a wiring issue just wanted to know if there was any common item that might be know about this topic. The bulbs are all new. The reverse lights do not work either but pretty for sure its unrelated.

Ford Wiring/Electrical :: 1990 F250 Hard To Start - Glow Plug Controller Relay Wiring

I just bought a hard to start 1990 F250. Per the board, just replaced all 8 glow plugs with Motorcraft. Still wouldn't start (it turns over but will only start if you use either). I attempted to install a new BWD brand (Borg Warner I believe) glow plug connector relay today...I removed the old no problem, but am unsure what wires to plug where....the only connection that I'm sure about is the blue wire that works the WTS feature...it plugs in easily but I don't know if there are other connections that need to be made or not? All the wires run from the posts and into the bottom of the unit.
