Battery Light on and flickers

Hello

This guide will help

https://www.2carpros.com/articles/how-to-check-a-car-alternator

Advance Auto parts should be able to tell you if your alternator was putting out steady and if bad. If they are not sure then go to Auto Zone (AZ) or O'Reilly's (OR) and for FREE they can bring their tester out and check your battery and alternator.

If the alternator checks good then it may be your belt tensioner is not keeping proper tension as the spring may be weak.

Thanks for the advise. I took the truck to a repair shop who identified that the alternater was defective. This was replaced and all is well now.

Hello

I am glad your vehicle is fixed. Thanks for the update

Hello Also, it looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.

Ford dealership condemned the battery, replaced no change
Mechanic shop condemned the alternator, replaced no change
Replaced harness from alternator, no more flickering light

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help

Cheers, Ken

Battery light comes on and off, had battery and alternator checked and they both checked out fine. What else you it be?

It checked out fine because you weren't testing is while the problem was present. You likely have a bad alternator but it can only be confirmed if tested during the failure.

yep, it was the alternator, had a buddy who is a mechanic hook it up and drive it around, voltage was dropping on the alternator when the light came on. Thanks for the quick reply.

Your welcome,
Positive feedback is always appreciated

Hi,

My battery warning light came on so I bought a new battery and hooked it up. After hooking it up, the warning light still came on. So I reconnected the old battery and tested it and the old battery is fine. The old battery is also receiving the necessary charge from the alternator. Is there any way I can reset this battery warning light? Do you think there is something else wrong? Thank you for the help.

Andrew

check fuses
Check charging system and suspect alternator

2001 Ford Escape 6 cyl Two Wheel Drive Automatic 132095 miles

The car in the last couple of years, has went thru two alternators. We had the car checked out by Ford dealer after it stopped running and they replaced the battery and cable ends. They put it on their tester and everything seems to be ok but when we got home after the 75 mile drive the battery light came back on. Is there something else we should be looking for?

Hi
Ford issued TSB # 01-20-2 on Oct. 15,2001 for a similar issue. They recomend replasing the 320 watt cooling fans with two 220 Watt fans. Does your problem occure in warm weather with AC on? if yes ask dealer to check out TSB may fix under warranty.
Hope this helps
Thanks for donate

I have a 2001 Ford Escape. The altanator went out in October of 2007. We changed it, and it went out again on January 25, 2008. My husband changed it on the 26th. The battery light came on as soon as he started the truck, and has come on and off since then. What is the problem?

Not uncommon to run into multiple alternator failures especially on partucilar brands. Some rebuilder's continue making the same mistake. If the alternator is not charging right, go to a different brand. I like the napa premium alternator myself.

It has been 100+degrees here the last 3 days. My battery light has come on and off. The car stalled a few times but has continued to run and start. The radio or lights have not gone out or dimmed. I just had a new battery and alternator installed in February.

The first thing you need to do is have the battery and alternator tested even though you recently replaced them.Also make sure your battery cables are clean and tight.Let me know what you find.

The battery Light stays on all the time on our 2001 Ford Escape...even though we replaced the battery with a new battery...the light just stays on

The battery warning light has nothing to do with the battery. It means the generator is not recharging the battery after starting the engine. Use an inexpensive digital voltmeter to measure battery voltage while the engine is running. It must be between 13.75 and 14.75 volts. If it is low, have the generator tested.

My battery light stays on most of the time especialy when i first start the car and drive 10 or 15 miles.

Have the charging system check could be the alternator is failing or a loose/open connection

fuses I still can't get fuses I still can't get the battery light to come on it only comes on when I touch the green and red stripe wire to the base of the alternator problem and help me get my alternator to charge or is the alternat and help me get my alternator to charge or is the alternator shot thank you

Do you have a multi meter to do some testing? You will need one.

Having similar issues in my wifes 06 escape 2.3 duratec to those in this focus thread: http://www.focusfanatics.com/forum/showthread.php?t=261352
Battery warning light keeps coming on mostly at idle. Battery and alternator have both been replaced.

I don't appear to have a main fuse but a metal "shunt" which goes across the 2 big wires that go to the under hood fuse box. We took it out and cleaned it up as well as tried replacing fuses for things like the alt or pcm. Also swapped around relays to rule those out.

Found the ground from battery to chassis looked a bit corroded to took it of and cleaned up all ends and sanded the connection points. Still no luck. Batt light keeps coming on.

The strange thing is that if I read the voltage with a multimeter from the battery positive and ground to the engine block it shows 14+ volts while running. If I ground the multimeter to the negative batt post or its grounding cable it shows a volt or so lower. Using the odometer voltage display it seems to get the same voltage that is shown by connecting to the battery ground rather than the block. Alternator which was just replaced thinking it was the problem is indeed putting out good voltage. The battery ground looks good and has been cleaned up. What could be causing this difference in voltage output readings?
The batt negative does have 2 leads coming off it. One is to the body that I cleaned up one disappears underneath and looks like it may connect to the engine. Any suggestions what to do from here please? Somehow its losing a volt or so...

check your fusible links pointed out in pic, test with a ight or volt meter shold be same voltage for both sides. also check fuses in picture there are two. this is for a non hybrid if hybrid it's different

Thanks I will check this. Is the link what the manual is calling a "shunt" in the under hood fuse box? Page 208

it might be you'll have to go to item 25 and see. but the drawing gives the location of those if you would read above it.

Thanks. Item 25 in the fuse panel is a small metal bar that links the 2 large wires that connect to the fuse/ relay panel which is in the front left area behind the battery. Doesn't look like a fuse but a small solid metal bar that screws down across the connectors of those wires. I will meter it and see.
Took it off and cleaned it yesterday but didn't see any cracks or signs of damage on it.

the parts i'm talking about are underhood don't waste your time checking he shunt. look at the pic isentinfirst reply if you have a 2.3L ther eis one an d3.0L there are two. BOTH UNDER HOOD

Thanks for your guidance and diagram! So the voltage seems to be the same on both sides of the fusible link. It's also the same whether we ground the multimeter to the block or batt post.

Discovered that the starting issue goes away if we use jumper cables to add a ground from the battery to block. I will replace the 2 grounds.

The strange thing now is that tonight the alternator voltage was the same if we metered it using the block or batt post as ground. The other day it was over a volt higher using the block as ground. Tonight though the alternator didn't seem to put out any more than 12.5 volts. Possibly the rebuilt alt is bad?

I guess we will see what happens after the ground cables are replaced.

The battery shows good voltage after I charge it and still showing 12.4 volts after starting it several times and running the engine for 10 mins with the alternator putting out low voltage. Could a battery with a bad cell cause a charging voltage problem?

Anyone have any insight on why my battery light flickers at high RPM's, after further testing while sitting idle I could only get the motor to up to 4000 RPM's (that was also the max, seemed like it hit a restrictor)and it also sounded like the engine was missing.

https://www.2carpros.com/how_to/battery.htm

if the battery has a bad cell it wouldn't read 12.4 volts. this battery should be load tested but other than that have this scanned as there may be something else causing the light to stay on. You'll need apro to do it.

I just replaced belt on my girlfriends 2003 ford escape and now none of the pulleys are turning and it squeals real bad. Looks like 4 wires where stripped when old belt broke looks like but can't tell they go to alternator would that be the problem or did I just do something wrong? Also battery light stays on now

check for a frozen alternator bearing if it is the replace belt and tensioner as well as alternator

The generator has to be tested while the problem is occurring, otherwise of course it's going to test okay. The most common cause of intermittent operation is worn brushes.
