SOURCE: 1999 Ford F150, Charging system.

Your battery may not be holding its charge. Charge the battery and take a voltage reading. Then after a few hours take another reading andsee if the voltage has dropped. If that is alright, refit the battery to the car. turn off all the electrics anddo a voltage test. If the battery is discharging then ou will have to find what componant is drawing the voltage. I normally check the boot through the rear seats first.

If u disconnect the batteries for 10 minutes, it will reset, but I think I'd check for engine codes to see why the light came on, as you may have a problem.

SOURCE: My 2005 ford explorer check charging system warning light

if charging light is on w/ engine running,the fault could be the alternator or another component of the charging system.remove, clean and tighten battery post connections to check for alternator output,use a volt meter or multi-tester set to 50 Volts DC,w/ tester on battery terminals it should read 12 volts W/ engine off;13 to 14 volts w/engine running.if voltage increases when alternator is spinning,suspect battery

98 izzu hombre 4.3 battery went dead after a jump it wont start how to fix


The jump start may have blown you alternator or voltage regulator. If so, you have an inactive charging system. You must have a good battery for this to work, Disconnect the positive cable to the battery. Use a battery charger to slow charge your battery. When the battery is fully charged, reattach the positive cable and try to start your engine. If it starts take the truck to a shop or auto zone to have the charging system checked. Fix what is needed.
Any time a vehicle is jump started, do so with the hot battery car not running and its ignition off. If it is running and your car starts one or both charging systems are usually damaged. There may not be damage if it is GM to GM or Ford to Ford, etc., but to be safe, do not let both cars run at the same time when connected.

2005 ford f150 stalls when driving pull over put in park no power to starter wait a few it starts goes a coupel blocks and stalls again


Hello, Try having your battery load tested. If it tests good, then charge it and try using it again. Check under your dash at the top of the Brake pedal lever for a dislodged or smashed Interlock switch. If it is a stick-shift, check the Interlock on the clutch lever. Check for clean battery terminals.

Autozone, Advance, and Oreilys will check your onboard computer free either with a scanner or you need to ask for a charging system check.

If you watch your dashboard Voltmeter, you will probably see it drop the charging after the vehicle has been run about 5 minutes . It will do the same thing after a jump start too. I have been told that you never want to jump start the newer Fords.

Many Ford, Lincoln, and Mercury products act this way. I have yet to see a TSB or printed answer from Ford on this problem. My opinion is that the Batterysaver feature is part of the problem with the Antitheft and battery being the other problems.

The Antitheft drops the Starter voltage to the Starter to 7 Volts or less, if it detects someone messing with the battery. The Batterysaver cuts off Parasitic power drains. Unfortunately the Batterysaver can identify your charging system as a Parasitic drain and disconnect that circuit.
This is because the Alternator uses power to generate output.

I have had clients whose batteries were completly drained at 70MPH when the charging system stopped charging miles earlier. So watch your Voltmeter before you consider it repaired.

Last night I got pulled over and so I shut off my car. When I went to turn it back on NOTHING at all worked, the hazard lights and the key wouldn't even work. we jumped it and put a battery charger on...


Hello, First, you will need to charge the Battery and have it load tested. The charging system on your vehicle may be bad. Depending on the Year and Model, there is sometimes an inline fuse from the Alternator to the main wiring.

On some Models, the Alternator wires drape over metal lines and brackets and wear through and short the system. Just gently lift up on those wires leading from the Alternator and watch for bare wire. If you come across a fuse, check it.

Ford systems are very sensitive to low battery Voltage. While the system uses a 12 Volt battery, the top charge is somewhere between 13.2Volts- 13.6Volts. As you can see, that is over a 10% higher charge to have all systems working perfectly.

When a Ford detects lower Voltage, the Antitheft system and the Powersaver systems can cause both starting and charging problems. The vehicles may indicate a charge for 5 minutes or more after removing an outside jump, then cut off the circuit (2004 till?).

Autozone, Advance, and Oreillys give FREE scans and charging system tests. You can carry in the battery for tests. Once a topped off battery is installed, you should have the Alternator tested. Even if a new battery solves your starting problems, get the charging system checked.

Has power but wont start or even turn over


Hello, Have the Battery checked. The Ford AntiTheft systems are sensitive for low batteries. When the system senses a problem, it can actually reduce the voltage to the starter to about 7 Volts.

Although the Battery is a 12 volt, the general full charge is 13.2 to 13.6 volts. The system can also interrupt the Alternator if you attempt to jump start the vehicle and drive away. After several running minutes your vehicle will completely drain the battery and die.

Once you get things going, go to Autozone, Advance, or Oreillys for a free charging system check. Ask them to do a starter draw test to insure the starter is good too.

Truck starts and then does'nt start


When you say doesn't start do you mean you have to jump start? If so it is something to do with charging system. If alt is charging fine, then you probably have a bad cell in your battery which would cause this type of problem. Sometimes it works sometimes it won't. Eventually it won't anymore without a jump.

Brand new 08 Ford Sport Trac (2 hr old) - won't start


Sounds like the battery may be bad. You could remove it and take it to a mechanic or parts store and have them test it for you. Mechanic might charge you 15bucks or so. Most parts stores will test it for free and gladly sell you a new one.
