Ford 7.3L Power Stroke (1999-2003) :: F350 - Battery Light Flickers Randomly

I have a 99 f350 7.3l 4x4 and my battery light flickers randomly. I have checked the alternator and both battery's. All brand new and seems to be ok. They only are getting a charge when the battery light is flickering. I put both new batteries in on Thursday and on Sunday I needed a jump at the store.

Ford 7.3L Power Stroke (1999-2003) :: Battery Light Came On And Would Flicker

Battery light came on about two months ago it would flicker. So i had Auto zone check it out batteries were good just needed a charge. so i charged them no fix so i said alright ill do the Alternator did that and then beginning of this week it happened again so checked it went back got a replacement alternator since they said it tested bad. Put the new one on and didnt change anything. Check my batteries they were reading 10v each. I charged them and they wouldn't hold a charge. so i replacement both batteries.

So i have a new alternator and two new batteries light is still on. Contacted my tech (whose a friend) he said to check the wiring going to the alt he said both wires should read 12v on constant other when the key is turned on. Tested the constant it has 12v other reads 6-8v with key on.

He also said sometimes the wiring on the X pipe can short the alternator? i unhooked all the wiring from the Xpipe nothing changed per battery light being on or off. So what should i do.?

Also my dash lights don't work but that's been like that for awhile (bulbs are all good).. Forgot to mention sometimes the light goes off but seems to stay on 90% of the time.

Ford 7.3L Power Stroke (1999-2003) :: Dashboard Warning Light For Alternator / Battery Occasionally Light Up While Driving

The past few weeks the dashboard warning light for my alternator/battery will occasionally light up while driving down the road. Whenever it does, my plug in voltage meter shows a healthy 14.x reading. It usually goes out after a few seconds, but will stay lit up for as much as thirty seconds. So other than voltage being too high or too low, what else will cause the dash trouble light to illuminate?

Ford 7.3L Power Stroke (1999-2003) :: Battery Light On Again - External LED Hooked To GPR?

External LED hooked to GPR

I have gone through around 7 alternators in the past 18 months. I currently have a new NAPA alt and new interstate batteries. Today I noticed that my battery light is on again. I also noticed that my yellow squiggly Glow Plug inrush dash light was on at the same time. However, I do not believe that my GPR was active BECAUSE... I have an external red LED that lights up any time my GPR is active. When my GP dash light came on my external light was off. I had just driven 26 miles and my truck is warm and the outside temp is around 70 Fahrenheit.

Ford 7.3L Power Stroke (1999-2003) :: Battery Light / Indicator Coming On

In the last couple of days my battery light comes on after about 30 mins of steady driving. I have no starting issues as of late. Batteries have been tested under load and checked out okay. Alternator is a few months old. Other than the battery light coming on there no other

problems, yet. Is my alternator over charging? A couple of month ago my truck would shut off when I turned a/c or heater on in the mornings. My alternator was over charging. After I replaced it I had no more problems. Could any of this be related to the life time led bulbs that I'm using?

Ford Super Duty (1999-2016) :: 2004 F250 V10 Battery Light Flickers

2004 F250 v10 xtl 260xxx. Started off by using my remote start, truck started up ran for about 5 sec then shut off, then restart itself and shut back off. When I manually started it, it ran fine. I noticed my battery light was on and as I was driving it would flicker. First thing I did when I got home was clean all my connections to see if that worked. Battery light still on, checked my volts on my battery and they were at about 11.8 with a slow but steady drop while truck was idling.then checked my alt, that too was at about 11.9 with a stead drop.

Alt was only about 7 months old and I had a warranty on it so I had it replaced at Napa and had them test it there. Good alt. Installed the new alt charged up my battery and turned it over. Battery light still on and flickering. Checked all my wires for corrosion, checked all my grounds. Everything checked out. Checked my battery again 12.4 with the truck off, cranked it over and it was back at 11.9 with a steady drop and almost the same reading with the alt. I replaced the battery as well yesterday, seeing how it was about 7 years old.

Ford 7.3L Power Stroke (1999-2003) :: Battery Light On Intermittently After Replacing Alternator?

Alternator locked up in a parking lot. Replaced it and had to replace pigtail due to a loose wire in the harness. Now battery light comes on intermittently. New alternator is doing fine producing anywhere from 13.9v to. 14.4v. No output voltage correlation to battery light at all. The belt is still in great shape so I don't suspect slipping. Fortunately I caught the old one locking up almost immediately and had recently replaced the belt. Output voltage looks great. Are there any fuses for alternator?

Only thing I can think of that I did...when splicing in the pigtail that connects to the alternator, I briefly grounded whatever wire in the pigtail is hot. Was just a split second, but enough to see a spark and maybe enough to blow a fuse? I've seen people reference an "under hood" fuse box, but I don't seem to have one. My truck is a 2002 CC with just over 100k on the clock.

Ford 7.3L Power Stroke (1999-2003) :: 2002 - Battery Light Comes On / Voltage Does Not Drop

Bit of a confusing one as of late. Doesn't happen every time I drive, maybe 50% of the time. When I start the truck up, torque pro reads voltage at 13.9-14.1 consistent. After 30 minutes it usually drops to around 13.7/13.8. Sometimes, battery light comes on, voltage doesn't drop. I can drive the truck, park it, turn it off, restart, no side effects.

I notice if I stop, turn off the truck, and restart it, torq pro will begin to read a voltage of 12.8.13.0. Sometimes it won't budge for an hour, sometimes it climbs right back up to 13.8, sometimes the battery light goes off, sometimes it stays on.

Alternator was replaced a month ago, both batteries replaced a week ago, all terminals cleaned and secured at the time of replacement. Truck behaves perfectly normal, I'm almost at the point of putting a piece of tape over the light and ignoring it, but was curious before I go that route.

Ford Super Duty (1999-2016) :: Battery Light Blinking / Flickers Like A Loose Bulb

The battery light blinks in my truck. It's not a controlled blink, but it flickers like a loose bulb. It started a week or so ago. It would blip every once in a while. Gradually it would start to flicker more often. At first I thought it was belt-related but it isn't related to the transmission shifting at all. So if you're thinking that it's belt-related, you're going to have to explain why it doesn't blink either right before or right after a transmission shift (i.e. a rapid change in engine speed).

Earlier in the week, the light was flickering so hard that it was virtually on. I drove home last night and didn't see it once, although that's the first time I haven't seen it happen at all in a week. The battery gauge itself doesn't move a bit while this is happening. I have a cigarette lighter voltmeter and it shows a pretty steady 14.1 volts regardless of whether the light is flickering or not.

I had the batteries tested in my truck by a real battery shop about 4 months ago and they are fine. The battery connections all seem tight and clean, and the belt, tensioner and all that seems fine. So..What can cause a battery light to come on that isn't voltage related?

Ford Super Duty (1999-2016) :: Battery Light Flickers On Highway Having 50% Charging - No Alternator?

for some reason my battery light flickers when im driving regular and on the highway. I have had both batteries checked and they were at 50 percent charge and both were good so therefore I assumed it was my alternator. I removed alternator had it check and it passed all test. Everything was checked at o'reilly and autozone

Ford 7.3L Power Stroke (1999-2003) :: Battery Light Flicker In Time With The Idle Of Truck

I bought a 7.3 f250 with 300k mi. It had a battery light on but didn't show any signs of trouble. Eventually started dropping volts a few days later and I replaced the alternator. The light is still on and flickers in time with the idle of the truck and sometimes goes out when I'm on the gas pedal. Some nights when the lights are on the voltage drops ever so slowly until its drained. Why the new alternator didn't fix the problem? NAPA's scanner says the truck has 12.4V at idle and 12.1V at idle with the lights on. Batteries are relatively new and test fine, dual Interstate Mega-tron Plus batteries-top of the line.

Ford Super Duty (1999-2016) :: 2005 F250 - Battery Light Comes On Dimly And Flickers When At Low RPMs

I've been having issues with the charging system on my 2005. The battery was 7 years old, so I replaced it. Now, the battery light comes on dimly (and flickers) when at low RPM. I am thinking alternator. I replaced one on my 2002 F150, but haven't done a 250. How hard are they to get to and replace? This is on a 5.4 gasser.....

Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 - Battery Light On When Truck Is Running At Less Than About 1200 RPM

Battery light comes on when the truck is running at less than about 1200rpm, but I see zero movement on the needle. Weird thing is i charged the batteries and tested the alternator with my multimeter and it was reading 14.1-14.2 which is nominal. Run it for about 10 min then it reads 12.3-12.8

I'm thinking a bad cell in the battery or alternator is going out. Oh and all the connections are tight, wires look good. 2001 f250 4wd 7.3 intake exhaust basic tuner gauges. Could the constant heat be a factor?

Ford 7.3L Power Stroke (1999-2003) :: Battery Light On / Voltage Meter Only Show Barely 12 Volts At Full Throttle

The brief information:

1. Stuck/non moving in traffic on the freeway for roughly 1 1/2. During that time the AC was running, but once I noticed my "battery light" on the dash turn on, I turned everything off.
2. Since then while on my way home from work the voltage meter only showed barely 12 volts at full throttle.
3. I charged my battteries, and started it up today to go into work. While going to work the voltage meter showed 14 at its high point, but shortly there after it dropped back down to 12. At which time the battery light came back on.

New battery or alternator?

Ford 6.0L Power Stroke Diesel :: When Turn The Key Clicking Under Dash And Cruise Light Flickers

I have been trying to diagnose my truck for 2 weeks now. Truck basically died at light. Towed to a friends shop, had ficm low voltage and crank and cam codes. He replaced crank and cam sensors with aftermarket ones from his parts supplied. I also purchased a ficm, still no start. When i turn key I get a clicking under dash and cruise light flickers, it does flash it flickers. If I unplug ficm relay or icp it will stop and crank over.i am getting a weird random off and on ficm sync.as well as cam crank sync.

If I unplug icp it will start for about 30 seconds then dies and as i am watch ficm and cam sync,when it says no is when it dies. Key on Icp unplugged. Here is Icp plugged in you can see cruise light flickers and check engine goes on and off but this is when it will grind starter. I'm starting to think maybe the motor fires briefly and then dies and starter is trying to engage moving flywheel.
