Ford Wiring/Electrical :: 1999 F350 - Alternator Over Charging And Gauges Stopped Working
We have a 1999 F-350 V10 super duty. The alt was over charging and the gauges stopped working. Replacing the alt, the guages still don't work, and the new thing is the charge light and selt belt light comes on. The fuses 29 (5amp)and 30(30Amp) which are supposed to be key on hot only are hot at the same time. With these on, it causes a drain killing the battery. Also if the truck is started, the lights go out, but when you try to turn the vehicle off, it stays running, one with the battery disconnected. The only way to shut it down is pull the fuse box power fuse, 50(amp)Some one had been in the dash before we got this vehicle and busted, burned out or removed the check engine light. I can read codes and their vehicle runs fair and does operate. Could this be a dash board? Also this problem appears when the truck is sitting, and the key removed nothing on. No fuses are blown either.

My steering wheel lights r out and need to know which wire runs power to those. also the led in my headlight switch is very dim.I checked the wiring and all the wires check out with high 11's and high 12 volts.i checked the volts at the led in the switch and it read 2.18 v.i have another light switch from the salvage yard and the same thing. which wire powers that light. also, the light only comes on when the key is in the on position or back for accessory. if i just turn the lights on it wont lite, only with key in ignition in those positions. truck is a 2000 f350 xlt dually.....

I bought a truck recently and I am attempting to get the alternator to charge. A previous owner hacked up the wiring pretty badly. We found that they had connected the voltage regulator to the horn relay for some reason. Anyway, I am trying to get it rewired and have searched existing threads for info and I thought that I had the wiring sorted out, however it is still not charging the battery.
The alternator has been tested and works. The voltage regulator is new. This is how it is currently wired.
Regulator A Terminal --> Battery side of started solenoid --> Alternator Batt Post
Regulator F Terminal --> Alternator Fld Post
Regulator S Terminal --> Alternator Sta Post
Regulator I Terminal --> Empty
Regulator body --> Radiator Support --> Alternator Ground Post --> Neg batt
When running, the battery is showing about 11.8 and slowly dropping as it runs. The truck has an ammeter in the dash, however it looks like it is no longer connected. Does it need to be connected in order for the alternator to charge the battery?
Ford Wiring/Electrical :: 1999 F250 - Alternator Fails At High RPM
I have a 99 F250 super duty 4x. It's all stock except for some speakers I replaced when I got it. The others were blown from my uncle. I don't have any amp or anything like that and the truck has ran fine for 3 years so I don't think the alternator has failed because of that. I'm thinking just age and 138k miles.
I was wondering what generation of alternator might be on there and how to tell the difference between the generations.
I have 12.5V with the truck off, about 14V with it on idle. As soon as I get it around 3000 RPM the battery light comes on and the voltage goes to 12.5V. Where can I get a rebuild kit for the alternator. I don't see anything at the major parts shops (napa, oreilly, autozone). Could this be the voltage regulator(that I did see at the stores)? I think its mounted to the back of the alternator. Is there any way to test the alternator further?
I'm a little confused as why it would be only above 3000 rpm. Are there two separate circuits for it? Like a low rpm one and then a different one above 3000 rpm?
Ford Wiring/Electrical :: 2002 - Alternator Quit Charging / Headlights Little Dim
I *think* I'm having trouble with the alternator on my 2002 Navigator with the 5.4L DOHC engine.
A year ago in Feb 2014 the alternator quit charging. I thought the headlights were a little dim, but when the radio turned itself off and then the heater fan did the same, I noticed that the alt light was on. Then the engine shut down about 1.5 miles from home.
I'd heard of war stories about rebuilt alternators so I sprang for a brandy new one. I also got a voltmeter that fits in the cigarette lighter so I can monitor the system voltage. All seemed good and the new alternator put out 14.2 to 14.5 volts. Except that the battery never seems to be fully charged. If I check the battery voltage with the engine off it typically reads 11.9 to 12.2 volts. I had Interstate Batteries check the battery. They thought it was okay, but offered to put a new battery in to keep me happy.
Six months and 8,000 miles later I'm up in Ontario back country (on vacation - no tools in the truck) and I notice the engine idles at 900 RPM instead of the usual 650 +/- RPM. Oh-oh, I also notice the volt meter is reading 11.9 volts and drops a tenth about every 10 miles.
Found a shop that was open and they installed a rebuilt alternator and it was putting out 14.2 to 14.5 volts. All was good (except for my wallet!).
Now, here we are six months and 5,000 miles later and the rebuilt alternator is struggling to put out 12.5 volts this afternoon. At a steady 50 MPH with the cruise Control on, the radio, and the heater fan on low, the voltage is bouncing between 12.2 volts and 12.7 volts.
Now to my questions:
1. Shouldn't an alternator put out 14.2 to 14.5 volts all the time? Not just when the alternator is new?
And
2. Is there anything on my truck that could be killing these alternators? Or am I just unlucky in the alternator lottery?

I'm working on the '73 F250 in my sig. I'm not very skilled when it comes to electrical work and I don't want to hack things. First up is I'm wiring a 7-way trailer connector with brakes. I need to tap into the brake light switch at the pedal, what is the cleanest way to do this? I was thinking of sticking a blade connector in the existing connector or adding a plug pigtail.
Also in the future I will (hopefully) be doing a 3G alternator swap and adding relays to keep my headlights from shutting off. I'm looking for suggestions on a junkyard or aftermarket fuse block that will accommodate the circuit breaker for the trailer brake, the 100 amp fuse for the 3g swap and the relays for the headlights.
Ford Wiring/Electrical :: 1987 - Died While Driving - No Spark?
So I bought my 1987 F150 XLT 4X4 (4spd) about two weeks ago and haven't had any issues with it so far... until now. As soon as I got it I did a full tune up. Changed plugs, cap, rotor, fuel filter, new battery, sea foamed it, fuel filter, ran a bottle of fuel stabilizer through it, new pvc valve, cleaned the throttle body, oil change, etc., ( all the usual things).
Was running fine up until two days ago when I was driving down the highway doing about 90km/hr in 4th when the truck suddenly lost power, sputtered and died. Tried to start it again and it will turn over but not start. So I get a nice expensive tow home and start to diagnose the problem. It is not a fuel issue. I can hear the pumps coming on, and fuel is coming out of the fuel filter so I cross that off the list.
Next I check for spark. No spark at all. So I run some tests. Battery is putting out 12V, about 10 when cranking. The solenoid is getting power and putting out power. No visible damage to any of the wiring, and all the grounds look good.
Next I just went ahead and swapped out the coil thinking that could be the issue. Didn't work. So I preform some more tests on the old and new coils. Both are grounded and having voltage pass through them. Next I take the TFI module off the distributor and check for resistance. Everything still checks out fine. Now I am thinking that the only thing left could be the PIP in the distributor. So instead of taking the dist apart and screwing around I go ahead a get a brand new dist and throw it in.
Now I am stoked and thinking that I finally fixed my truck and go to start it up and.... no spark. It still turns over but no start. I am trying to provide every bit of detail that I can. When I say I tested all the components I mean I REALLY tested them. I did both tests from the Haynes manual and from various sources off this site.
I am almost at the point of getting it towed to the shop, which I really do not want to do. A day before this happened I degreased the engine and VERY carefully sprayed it off with water. In the process I am thinking I may have damaged something?
Ford Wiring/Electrical :: 2000 - Electric Shift Transfer Case Wiring Diagram?
I am curious if it is possible to make a stand alone controller for the electric shift transfer case in a 2000 F-350?
The reason I ask is, this is swapped into a 4x4 conversion in a van and I would like the transfer case to work like the factory, but I don't want to swap over the whole GEM module. I have the high to low and low to high shift relays and wiring, the selector switch from the dash.
I know that powering up the relays will shift the transfer case, but the GEM module tells when the relays need to shut off, and that is where I am not sure what to do. I am assuming that the other plug on the shift motor (6 pin plug) is the sensor that tells the GEM module where the shift is at.
What needs to be done (with a bank of relays).....
Ford Wiring/Electrical :: Duraspark Module Overheated And Engine Died
My points to electronic conversion suffered this problem, just started, set the timing and was idling, like ten minutes or more, suddendly the engine died, no spark, immediately I noticed the module was very hot, so was the ignition coil, it's a TFI "square" coil from a 1987 Econoline I6, the module is a new Spartan brand name blue module.
I cooled the module with a wet rag and the engine came back to life. I hooked up the module and the coil with full 12V, no ballast resistance for the coil, I'm feeling this is the problem, maybe this coil needed a ballast resistor?
I have this 1.6 ohmm ballast, if I install this, will the coil run cooler and put less strain in the module, so it won't overheat? or the TFI coil is wrong for the Duraspark ? it was running fine with the points, never missed a beat, never tested how hot it run with the points though, but I did used the ballast resistor with the points.
Ford Wiring/Electrical :: 1984 F150 4x4 - Died While Driving - No Spark?
My '84 F150 4X4 inline 6 Died last night while driving. just conked out and died right there on the spot. no sputter... no gasping... just instant death...
after some investigation i found i wasn't getting spark anywhere. not at the plugs, not at coil. I have replaced the ignition module to no avail. still no spark I am going to swap in a the coil tonight. sure do hope this works.
Ford Wiring/Electrical :: F350 Truck Would Act Like It Ran Out Of Gas Then Pick Up And Go Again
Truck is up in the back country and has quit. It has two factory gas tanks, I can't hear either of the fuel pumps will come on when you turn the switch on. The problem started as an intermittent fuel starvation issue. Truck would act like it ran out of gas then pick up and go again. Switched tanks back and forth but it got worse throughout the day and finally will not start at all. I have listened to both tanks when the ignition switch is turned on but can not hear the pump come on for either tank (switching the selected tank with the switch on the dash). We went through some bumpy terrain just before the problem started so I am thinking maybe a wire might have come loose or got broke somehow. I am asking for wiring schematic so I can check for voltage in the correct place going to the fuel pumps. Both tanks are full of gas so for now dropping either tank is not an option.
View 8 RepliesElectrical-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?

I have a 2006 F350 Diesel. Had one of my employees go out to start the truck yesterday and when I went out I had no electrical power to most of the accessories (gauges, warning lights, power windows, radio, interior lights, turbo charger). It also seems to have no power - could barely make it go up the slight incline into my garage. I have checked all the fuses - they seem fine. Although put a tester on the interior fuse box and I don't have any power to the fuses that run these accessories.

View 2 RepliesFord Wiring/Electrical :: 2008 F350 - Battery Frequently Dying
My truck has been sitting more lately, which means up to a week without starting and running. Each time this happens I run into a dead battery. And I mean dead. I've charged it full and then used the truck no problem.
We did a test where we unhooked the negative terminal wiring clamp and ran a meter to check for amp draw. We did this by touching the meter leads to the negative post clamp (unhooked) and to the negative post on the battery. It gives a reading of ~1.5 amps. Trying to figure out where the drain might be.
We'll jut pull each fuse to see if we find the electrical area drawing the amps.

Ford Wiring/Electrical :: 2007 F350 - Parking Lights Won't Work
I am beginning to think that I need a whole forum dedicated to my trucks wiring issues ... I finally got my reverse lights to work but my newest issue Is that while driving tonight i lost power to my parking lights, my instrument cluster lights, and my heat control lights... everything still works inside (gauges all act properly but they won't light up) and i still have turn signals and brake lights, and headlights. I really don't know where to start with this one. I don't have an owners manual so i can't figure out what fuses to check or what relays to look at. It is a 2007 f350 diesel....
