2003 Ford Windstar: Check Charging System alert

A few days after having my air conditioning system charged (refilled or whatever the proper term is), my Check Charging System alert came on my message center (along with the battery light on the dash and the alert "ding"). I had my alternator replaced in March, so I was pretty sure it was not the alternator (plus it was under warranty). I took it into the shop and they confirmed that the alternator was working fine, but it looked like the cap (again, not sure if that's the proper term) that holds the wires to the alternator needed to be replaced as the wires were stretched and worn. The technician had explained that the while the alternator was charging my battery, it was not doing it while the engine was idling only when the rpms were in a cruising level. He said the van wouldn't leave me stranded, so I took it back on Friday to have the part replaced. After leaving the shop and taking my kids to the movies, the alert came on again. On my way into the office yesterday morning the same alert came on followed by and alert (nothing in the message center) of the ABS, Activetrac and Brake symbols on the dash. The two separate alerts took turns flashing on every five minutes or so on the drive to the office. I called the mechanic and explained what happened and he suggested that he'd need me to drop off my van to take a longer look at it. I explained that I'm off on Friday for the holiday weekend, so that would be a good time for me (this was after he advised that it is most likely not something to be overly concerned about, but something we'll want to fix). I don't really know much about cars, but I do know computers. I was told a while back that if you don't address things quickly enough in this van that the computer will start "yelling" at you with alerts. I am wondering if perhaps since it took over a week to get the wire thingy replaced if the computer was yelling at me and perhaps now it's not registered that the part has been replaced as the computer needs to be rebooted (like installing or uninstalling some software on windows requires a reboot). If that's the case, is there a way for me to reboot the computer myself? I would be more concerned if it weren't for me having a total checkup (including the brakes) in March when the alternator was replaced. Thanks in advance for your help and answers.

The computer system learns failey quick on vehicles/not the problem,,,have the tech, check battery load check,and check it for ac voltage if ur old alternator ,before it went out completey ,was charging ac voltage ur battery would have been sort of modified to ac voltage and now would be putting out some ac voltage,,,,this woul cause the problem ur having ,,,of course,me i would take the alternator back for a free replace ment and install a good 65 series battery or orbital or such brand so u have more than enough reserve power on hand and alternator doesnt have to work as hard

2003 Ford ka what colour is the wire for the alternator warning light on dash cluster


There isn't one ! This vehicle relies on serial data communication . The PCM sends an message on the data bus to the microprocessor inside the instrument cluster . The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The warning indicator will also be illuminated by the PCM at key ON engine OFF, and stall conditions.
Charging System Warning Indicator
The instrument cluster receives the charging system status from the PCM over the SCP or CAN communication network. The PCM controls the charging system and the charging system warning indicator. The PCM is therefore responsible for turning the lamp off once the system is running and illuminating it under fault conditions (including stall conditions).
How to Diagnose Controller Area Network CAN Your best bet would be to take your vehicle to a qualified repair shop .

Overheats could this be from to much coolent rushed the radiator and refilled just Wonder if added to much coolent


If you have emptied the cooling system and refilled it, you need to bleed air out of the system using the correct procedure for your engine.
If you did not bleed air out after refilling, you will have air trapped in the cooling system and it will not function properly. You will most likely get an overheating condition.

Battery light stays on after changing battery,alternater & plugin.


Is the system charging? You should have 14.2 14.6 volts at the battery. The charge light is controlled by the alternator internally. If the charging system is working, you could have a bad diode inside the alternator keeping the light on or a short/grounded circuit to the battery light

2003 windstar alternator over charge I try 5 or 6 alternator diferent companie always the same problem go up to 18.80 v help me please


it should notgo over 14 1/2 volts.

Get free DTC codes scan from Autozone. I think you will get DTC code 1246 - System Voltage Malfuction.

The I (indicator) (BAT light) wire activates alternator field circuit.

The heavy B wire circuit sends current to the battery for charing and to run the car.

The S circuit helps control the amount of charge. I suspect yours is not controlling. This car has the PCM (engine computer) help control the output and turn the BAT light on when under or over charging.

SECTION 414-00: Charging System - General Information 2003 Windstar Workshop Manual
DESCRIPTION AND OPERATION Charging System This vehicle is equipped with a powertrain control module (PCM)-controlled "smart charge" charging system. The PCM-controlled charging system is a system whereby the PCM determines the optimal voltage setpoint for the charging system and communicates this information to the voltage regulator. The PCM-controlled charging system is unique in that it has two uni-directional communication lines between the PCM and the generator/regulator. Both of these communication lines are pulse-width modulated. The GEN COM line communicates the desired setpoint from the PCM to the voltage regulator and the GEN MON line communicates the alternator load condition to the PCM. The third pin on the voltage regulator, the A circuit pin, is a dedicated battery voltage sense line.
-------------------------------------
  • Charging system malfunction (high or low system voltage)
  • possible causes:
    • A circuit 35 (OG/LB).
    • A circuit fuse link.
    • B+ circuit 36 (YE/WH).
    • B+ circuit fuse links.
    • Generator.
    • PCM
    • GEN-COM circuit 586 (RD/PK).
    • GEN-MON circuit 585 (VT).
    -----------------------------------------------------------------------------------
    Generator The generator (10300) on this vehicle is monitored and controlled by the powertrain control module (PCM). The PCM monitors the voltage regulator and sends a duty cycle command back to the voltage regulator to regulate the amount of field current supplied to the generator. The generator has an internal voltage regulator. The generator and voltage regulator are installed as an assembly.

    Check charging system light keeps coming and dont know why


    Have you checked your belts and charging system? The light is telling you that you have a problem in the charging system. This could be the belt, battery, loose wire or alternator. You need to to address this or you may get stranded somewhere with a car that won't run. Once you perform these checks you'll find the problem and can repair as needed.

    Air condition blows hot air but it has freon


    You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....

    I have a 99 windstar. I replaced battery and alternator. charging system checks out Good. 14V charging and good battery strength. Battery light still on. I have been driving in this condition for 3 days...


    With the battery light on and at 14 volts I would suspect that the diode trio is going out and over charging the battery, first check that the battery has fluid in it all the way if it does then have it load tested at a battery shop like all state or sears or any parts store can do a load test for you. Just because it's putting out 14 volts does not mean it's putting out enough amperage, the light is giving you fair warning of an impending problem, have it checked at AutoZone or shucks it does not cost nothing and they can test the alternator output as well.
