Having problems with your 2001 Ford Expedition ?
What does it mean when your battery light comes on?
All cars have a battery light on the dashboard that is designed to warn you if the recharging system fails. A simple circuit looks at the voltage that the alternator is producing, and turns the battery light on if it is low. The battery light indicates a battery charging problem. If the battery light comes on and stays on while you are driving, the most common cause is a broken alternator belt. Total failure of the alternator is another possibility.

Diagnostic then reads fault code 'POA09 - Converter status - Circuit low input', but no-one at Jaguar knows what this means! Great, anyone got ant ideas?

I have a 2001 Ford F150 truck and no owners manual. Recently the red battery warning light comes on at idle speed. Sometimes it flashes and sometimes it stays on. I also have a battery guage that at the same time is in the mid-range between High and Low. What does it mean when this warning light comes on?
You should be able to download an owner's manual from one of many web sites for a nominal fee. If the battery warning light is on, it could be the battery or the charging circuit (alternator). Check the battery connections first and the battery. I ... 2001 Ford F150 Styleside SuperCrew
Electrical car was jumped several times for days and days. no problems, finally had battery replaced and terminals, right after battery dumby light comes on and 20 min later the car went crazy and died out, dash lights faded , car spuddered, lights went out, i mean it just died !!!! had to jump it with a brand new battery to run only for 20 seconds before it went crazy again and just died. what happened? did they hook something up wrong or cross wires when installing new terminals?
With the computers and complicated circuitry in newer model cars, jumping is not a good idea. Not only can you cause damage to your battery and fuses but you can fry entire electrical systems. Try checking fuses first. Then relays and wires. If your ... 2001 Chrysler 300M

After driving a short while, engine control system light comes on and stays on. "Service engine soon-refer to owner's manual" is displayed. I don't have a manual. What does the light mean? Car seems to drive fine. No other warning lights come on. Engine data on display shows nothing abnormal. If car hasn't been driven for a while (2 weeks), the battery goes dead. Thanks, Donna
My Engine Control Light comes on in the hot weather. The car idle now runs very high when I initially start the car and any time I stop for any period of time. Is it a bad ECU? Is it a do it yourself job and how much does it cost? ... 1988 Cadillac Eldorado
91 accord lx overheating, leaking fluid but no smoke or steam? i have a 91 accord 180,000 miles awesome car but just now started over heating. no smoke or steam are coming out i don't know is that means anything. there is a small leak coming from just around the battery. the fluid is light green i cant see EXACTLY where its coming from its just above the battery somewhere. i placed water in the radiator theres not a leak there or from any visible hoses from what i can tell. i towed it home i can
The green colour will be antifreeze additive in the water, you should really trace the leak source as it is bound to continue or worsen without repair. You could try a product called CE-LIT which comes in little packets, looks like chopped up grass o ... Honda Accord

Check wires to make sure they are secure on the starter, alternator and battery. Also check fusible links. Fusible links are fuses within the wire. These are usually found near the starter. It could be that the wires are brittle or broken and not ... 1983 Pontiac Grand Prix
When im sitting at a red light, the check battery light comes on and it will idle really low to the point where it feels like the engine is about to die but it never does, what does this mean? also another question: sometimes when i first start the car up the speedometer shoots back and forth while im driving until i drive about 3-5 miles and it goes back to normal, what does that mean as well?
First question, it sounds to me like your altenator. If you hear a squeak coming from under the hood, it could be your altenator. If you do not hear a squeak, that does not mean it is 100% not your altenator. There is still a good chance that your al ... 1990 Chrysler New Yorker
!999 Saturn. Occasionally when I first start it, 2 dashboard lights come on in the upper right of my dash; one looks like a battery and to the left of that looks like a thermometer. It's a fairly new battery and once the car runs for a minute and I restart it, they don't come back on.....what do they mean?
I am guessing these are the battery and oil light indicators. Check your oil level IMMEDIATELY. Make sure it's full. Your battery level may also be low; however these are normal to come on right before you start almost any car and they'll go off a ... 1999 Saturn SL
I own an 03 tiburon GT, and the light for my turn signal driver side stays on when i turn off my vehicle, and when i do manage to turn it off, i put my alarm on, and it will come back on. Also, i put my car in storage, and i bought a new battery for it, and i start it every once in a while, but i didnt start it for a month, and the battery is dead, the other problem is my reverse lights will not engage when i go into reverse...does this mean that there is an electrical problem? If there is, i ca
All exterior lights run through a body control module on the left side of the dash. Inside the body control module there is a relay that might be sticking. You might need to replace the body control module to fix the problem. ... 2003 Hyundai Tiburon

I bought a 1983 caprice wagon in very good condition. I changed the battery and the check engine light went off, but now the battery idiot light comes on. I disconnected the positive cable while the engine was running so that means the alternator is okay right? What else should I check?
Is the light staying on steady, or intermittantly coming on and off. if its going off and on, off and on, then the alternator is going bad, not out yet, but close i wouldnt trust it... if its steady, im not really sure what it would be... hope this ... 1983 Chevrolet Caprice
My battery light comes on all the time, does that mean I need a new battery
Maybe, but probably not. Generally, when the battery light comes on that is an indication that your alternator is not charging your battery. Have the alternator and battery tested to find the cause. ... Cars & Trucks
Had OBD2 codes P0441 & P0446 on my 1999 Toyota Corolla. Replaced the VSV CHARCOAL EVAPORATORE, disconnected the battery, check engine light went out. came back on this am, took the car to advanced auto & rechecked. The P0441 & P0446 codes were gone, but had a P0125 code showing. Reset & the lights out now. The guy at advanced says that lots of times other sensors will get tripped and it should stay out now that we reset, but not real sure what a P0125 code means or how to fix if light comes back
According to my 2002 Toyota Tundra manual (and it may be different for your car) P0125 is as follows:Insufficient Coolant Temperaturefor Closed Loop Fuel ControlThis would seem unrelated to your original problem. ... 1999 Toyota Corolla

The battery light has just come on for my 2001 vw golf. what does this mean? how do i know if it's the alternator, battery or something else? and how much should a new battery or alternator cost. FYI this is for a UK car
When the light comes on, it is a signal that you are using more electricity than is being produced, below some threshold. If it continues to stay on when you rev the engine, it is probably your alternator. A 9 year old vehicle is a candidate for a ... 2001 Volkswagen Golf
My nisson 300ZX has been in storage for several years and the battery was disconnected. We connected battery but nothing. However, the security light comes on and flashes. Does that mean the battery is dead or is there something else we need to do to get the car to start. Thank-you Unhappy car owner
Several years in storage without being started would be a problem on the battery, even disconnected. I'm sure a jump would start the car but I doubt the battery would hold a charge. How old is the battery? If it were 2-3 years old already it's probab ... 1989 Nissan 300ZX

What does it mean when the battery light comes on and the steering is hard when turning. There is power steering fluid in the vehicle and the battery is new.
I would say your drive belt isn't turning the alternator or the power steering pump.Either the belt has come off, the tensioner isn't holding the belt tight or one of the rotating pulleys is seized and not allowing the belt to turn.If the ... 1996 Ford Explorer
