'03 E250, standard van with RKE if that's pertinent.............
Looking to replace the on-board 4-way flashing system with Whelen strobes and looking to have the column mounted button be the on/off switch for that power supply. I have a schematic from a '97 E250 (almost identical FWIW) which I can post the pin out, test procedure and EVTM version of the hazard portion of that Multi Function Switch if that's useful.
I know it would be far, far less complicated to control the Whelen via a separate switch but this above reversible mod would be somewhat cool IMHO.
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 :: 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?

My dome light does not work and door ajar light is always on. I cant even turn the light with the switch on the side. Just don't know where to start. Do you think it is a switch on one of the doors? I have tried spraying cleaner and WD40 in there but it has not worked. Its been this way since I bought the truck but it is starting to drive me crazy....

2006 F-250 SD... I Keep popping the 15A #17 fuse under certain conditions - Driving forward
1. Start with good fuse.
2. Start engine, while in park, turn on parking light...4.8A on circuit. No problems.
3. Put into reverse and drive. down the block around the corner and back up to the house... No problem. 4.8A on circuit.
Put the shifter into drive and - POP - the fuse goes. I never see a jump in the current. 1-5 seconds until fuse goes. While conducting testing, I have had the fuse blow when shifting from reverse to park. Looking at the wiring diagrams, I don't see a common wire that would cause a short when shifting. What I should try next?

View 5 RepliesFord Wiring/Electrical :: 4x4 Light On The Dash Has A Small Delay
When the 4x4 switch is moved to 4x4 high, what is the sequence of operation?
I note the 4x4 light on the dash has a small delay. Does the switch engage the transfer case and draw a vacuum to the hubs or does the transfer case engage first and then close a relay to light on the dash and engage the hubs? I have hubs that are not working, but no detectable vacuum leak, a dash signal lit for the 4x4, but a wheel still turning freely. My vacuum hoses are all soft and pliable.
I'm trying to figure out what my dash signal is telling me, if anything, before proceeding. Fuse for transfer case is good.
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 :: 1990 F150 - Center Brake Light Went Out
My center brake light went out a month ago. Thought it was the bulb so replaced that, still didn't work. Checked the fuse and its not broken so my guess was electrical?
Hasn't come on once that I know of but I was randomly walking behind my truck and the light was on. Truck was off lights were off and key wasn't in the ignition.
Went and turned my truck on and turned the lights on and the cbl stayed on. When I switched my lights off it went out and stayed out.
Now I'm definitely thinking wiring but not sure where to start fixing?
Oh and it's a 1990 F150 XLT

View 14 RepliesFord Wiring/Electrical :: Dome Light Doesn't Go Off When Close The Door
I just purchased a 2006 E-350 15 passenger van. ~85000 miles. As soon as any door (except the very back door) opens, the dome light comes on, as expected. However, when you close the door, the light doesn't go off. There are two ways I've found to make the light go off:
1. Reach a speed of 10mph
2. Wait several minutes (i haven't timed it yet, maybe 10 min?) without opening a door
I've read that the keyless entry remote can control this, but this van isn't equipped with keyless entry. There must be some factory setting that can be adjusted. Also, any thoughts on adding an aux jack to the stock AM/FM/CD stereo? Maybe I should bite the bullet and install an after-market deck?
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...
View 4 RepliesFord Wiring/Electrical :: Dome Light Not Working - Tested Almost All Components?
I can't find out why my dome light doesn't work. I threw a bulb at it first, and then a tester but found no voltage with the door open or the dome lights dimmer roller clicked over to "interior lights on". I do get a door chime with the door open, so seemingly the door switch is working. Fuses 4 and 14 are good. They seem to be the related fuses.
Here's what I've checked.
1.. Fuses are all good.
2.. Removed and tested the relay. It tested properly, closing the large contacts when voltage is applied across the two coil terminals.
3.. 12V is present at the large left contact in the relay plug.
4.. I applied voltage to the relay output pin (the large contact next to ^^) in the fuse panel and get the dome/cargo lights to illuminate, so I know the wiring from the relay to the lights is good.
5.. The two smaller relay pins upper and lower look to be the relay coil/turn on contacts. (The middle contact is not used) There is 12v on one of them and it seems the other should be grounded with a door open or when the dash roller is rolled past the detent. I'm not getting this grounding signal.
6.. I do get a warning chime if I open the door while headlights are on etc, so it looks like the door switches are working.
Just got back in from some more testing... Here's a breakdown of how the relay works:
- Relay socket we're looking at is the upper socket.
- High amp 12V power is on the left large vertical contact. The relay's function is to port this voltage to the middle large vertical contact. (the load contact)
- The middle vertical contact (load contact) goes to the dome light and cargo lights.
- The upper horizontal contact is one end of the relay throw coil. This one has 12V present when probed.
- The middle horizontal contact is not used. (actually it's an empty socket with no female terminal behind it.)
- The lower horizontal contact needs ground applied to it to get the throw coil to close the high amp contacts.
With the relay plugged in, I was able to sneak a thin probe to the lower horizontal contact and ground it. The relay activated and the lights came on. So, for some reason I'm not getting the grounding signal to the relay with the dome light rocker or the doors open even though I get the door chime.
Apparently there is something between the door switches and the dome light/roller switch and the relay? Is this the GEM module? If so, I don't see the reason for anything between the switches and the relay? It should be a pretty basic relay circuit?
Is this something (GEM?) programmable, or testable? I don't want to throw parts at it. Looking for a wiring diagram, a diagnostic flow chart or a pin out?
