Ford Wiring/Electrical :: 1976 F250 - Alternator Not Charging
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 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.

I have a 1981 F100, lately when I've been driving at night I notice my headlights, dash lights, and charging light will flicker at the same time, and even sometimes my headlights will flash on and off by themselves.

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 :: 2002 Escape - Headlights Do Not Illuminate
On my 2002 Ford Escape my high lights do not illuminate. I changed the light but it does not light up.
On the dashboard, the little blue light does not turn either to indicate that the switch is high.
Is this a relay, where it is placed? Otherwise what would be the problem?

My alternator quit charging last night. Was pretty much a sudden onset as I was driving down the road and left off the accelerator the battery light came on and lights dimmed a bit. When I stepped on the accelerator again they bat. light went off and the lights came back up.
At idle I'm at 11.77v. I've pulled the plug on the back of the alternator and I'm getting voltage on both the red and green wires that go into the plug with the engine running. Is this correct?
Toyota - Electrical-wiring :: 2002 - Random Flashing Headlights
I have a 2002 Toyota Corolla. The issue I have been having is that the headlamps and tail lamps are flashing randomly. They flash for about 10 seconds then stop for about 30 seconds then flash again. There is also a clicking sound(similar to the one made when the hazards are on) heard from the inside. I know it is not the hazards because when I turn the hazards on their is another, separate clicking noise made and the flashing lights are brighter. I have attempted to reset the computer, pull out and put back in all fuses to no avail.

I have a F250 towing a Big trailer and the RV folks have told me that while the factory seven prong will supply power to the RV, it would take a days to charge the RV batteries. So...
1) Does the connector not really significantly charge the batteries?
2) Is there a faster way to charge the RV batteries while driving?
3) Would instructions something like I found at How to Charge Two 12 Volt Batteries on an RV Towed by a Ford F-150 | etrailer.com work?
4) Would #3 eventually tax my alternator so badly that I kill it?
5) Would #3 fry the electronics in the trailer?
I'm trying to charge 2 6-volt marine deep charge batteries in series.
Ford Wiring/Electrical :: 1963 - Replaced Generator And Regulator Still Not Charging?
I have a 63 Falcon that the generator went out on. I replaced the generator and the regulator and it still isn't charging. A friend of mine told me if I disconnect the FLD at the generator and connect a jumper between FLD and the battery + terminal it should start charging which it does. I have swapped out two different generators and regulators now and it is still doing it.

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?

Over the weekend I was driving my 2000 F350 and the alternator died (found out later). The shop said they replaced the alternator but it wasn't charging. They later told me it was because the isolator failed. My 2nd battery WAS a yellow gel battery. Before the battery (in series) was an 50 amp circuit breaker...........that blew apart.........and the battery had a melted off side terminal. It looked like the 'sealed gel battery" had been 'leaking for a while" (as there was funky acid type white corrosion deposits in a few places. Any speculation what happened here?

I have an 03 F350 Lariat, the overhead console display quit working awhile back (about 18 months ago) and so far my only option is to buy a new one from Ford. I have looked online, on ebay, local wreckers and have come up with nothing. I have come close a few times but the wrecks didn't have a sunroof so the display is different. I searched and found ways to fix the resistors but mine do not seem to have the poor solder problem that some do. Where I can find a replacement display?
View 1 RepliesFord Wiring/Electrical :: 2002 - Complete Headlight Switch Wiring Diagram?
Any COMPLETE headlight switch wiring diagram? Everything I find online only shows 2-3 wires in each sub connector, nothing with all wires and colors, and what they do. and of course the factory service manuals no longer work on my new computer. the switch and associated wires went up in smoke 2 hours ago, and this truck is my only means of transportation rite now. what i need is headlight wiring with colors so i can temporary hook up a toggle switch to have lights until the new switch and connectors come in next week. I went to pull the switch and connectors out of the parts truck, but of course that does not have fog lights so it uses different switch and connections.
