Ford Wiring/Electrical :: 1999 F350 - Alternator Over Charging And Gauges Stopped Working
Sep 8, 2013
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 father in-law gave us a 1996 explorer AWD with a 5.0 for my son who is 16. A couple of weeks later he's out learning with my wife and a very strong electrical smell took over the cabin. They came right home and when I got in I found all of the gauges not working. The instrument lights work, blinkers work, but all gauges do nothing. Pulled cluster and wires look O.K. behind it from what I can see. They saw no smoke, just smell, fuses look O.K.. What could cook on this vehicle that would wipe out just the gauges?

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?

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 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?

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 early 99 F250. The a/c compressor stopped working. Have checked pressures, switches, freon etc. Found the switch in the dash is not getting power to send to the compressor. Where the feed for this switch is? I have checked all fuses, all good. The manual does not show a relay as being an a/c relay, so I am stumped without taking it somewhere now but I would like to avoid that.

My radio, all gauges and windows aren't working. Fuse 17 did not seem blown but I changed it anyway and still no luck.

I have a 2000 F350 4x4 with 7.3L diesel and a manual transmission. While driving home yesterday my gauges (fuel, temp, volts, oil pres) stopped working. Within a couple min the speedometer and the tach also stopped working, but the truck was still running fine. Within a couple miles the engine stopped running, just like I had turned the engine off.
After having it towed home I checked all the fuses, none are blown, but there is no power to fuse #16 (15A, instrument cluster, high beam head lamp). Also in the fuse box under the hood, again, no fuses are blown, but fuse #9 (left head lamp low beam) and #11 (right head lamp low beam) have no power to them.

2002 f350 super cab 7.3 diesel, replaced alternator because wasn't getting charge to batts, Napa guy checked batts and determined no charge, replaced alt, still no charge, have 12v at alt post with engine running or not. My ? is, is there a fuse in here somewhere that I'm missing? Went through all fuses in fuse panel all good.

I am working on my son's 1997 F-150, 2 wheel drive, 4/6L truck. He was driving it when the gauges and the tach stopped working. I replaced the cluster and it still blows the fuses. The five amp fuse that is specifically for the cluster doesn't blow. It is a twenty five amp fuse that also power the overdrive circuit, etc.
After replacing the gauge cluster I installed a new fuse and the overdrive button on the shifter started smoking. Where I could get a wiring diagram of this circuit so I can see how it is wired.

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?

I was replacing the dome light in my 06 Ford F350. I tested the light and it worked then while screwing it back in, the lights when out and then the radio. I suspect it may be a fuse, but have yet to find the culprit.

So I have an 04 F250 Super Duty 6.0L and suddenly the turn signals and hazards stopped working. First I replaced the switch on the steering column...no luck. Today I replaced the flasher relay under the dash panel (the blue one)...still no luck. I remember checking fuses in the fuse box but don't remember which ones I checked but I didn't see anything obvious. I also took a quick look under the dash at all the wires for any anomalies...nothing. I'm lost... What to do next!?

I'm having a problem with my interior dome light and my door chime bell not working in my '01 F-250. I found that the bulb was blown,so I replaced it thinking it might fix the door chime bell also, thinking they were wired together from the factory.
The new bulb didn't fix the problem. I recall that when I noticed the door bell didn't ding-ding anymore was about the time(when it got dark), that I noticed the dome light was out also.
What I may check? The fuses all work, the interior dome relay switch works and I see nothing else in the owners manual to look for as far as dome lighting and door bell chime.

I have a 2005 excursion with about 112,000 miles and last week all 5 doors decided to stop working on me when trying to lock or unlock with the remote or the door switch. I do hear a sound like something is happening just right of the fuse box. I did a little research and found that this is a wide spread problem. I did order 4 of the 5 actuators and I replaced the drivers door but nothing yet. Do they all have to be replaced in order to work? Or is it most likely something else causing this? Just trying to figure it out before I install the other actuators or take it in to a shop.

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.

I have a 1999 f350 crew cab. There is a gray box with some wiring running to it and when the door is open I here a little cracking and popping sounds. It is between the steering wheel Column and the ashtray under the dash. I can hold it and feel it clicking and popping, What that is called, or how to get it out to replace it?

I have checked the fuses for the Hazard and the Turn Signals. Both look fine. I tried replacing the turn signal flasher (which was a task in itself). After all of this it is still not working. What else could it be? Simple short?
