Try replacing the "convinence control module" and bad board can cause all elec issues explained and also cause engine to cut out and other things but that is where I would start, hope this helps-

Is there another name for this part? I completely lost trying to figure out what this is. The only things that come up are the ECM and ICM.
Assuming ECM would be the one you might want I am guessing others would call it that if it stands for Environment Control Modual, if so then yes they are the same and no it is not the ICM that is your ignition control modul. If changing the ECM if not to expenisive doesnt work then you have a fault in your wiring harness and need to follow wires until you find a bad spot because if it is not the ECM then it must be a wire grounding out somewhere, it is a pain in the back side to chase wires but once found easily repaired. If you end up chasing wires I would start from the front of the vehicle and work to the back, it is most likely in the engine cradle area or along the frame. hope this helps-

SOURCE: 1998 windstar van: charging system light goes
It could mean the alternator has gone bad already... with the car off, the battery leads should read 11-12V.. with the car on, the battery should read 13-14V.. if it's lower then it's not charging your battery and if it's higher, it's damaging your battery....

check the alternator fuse and grounding
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

you have a voltage drop.fine the damaged wire going fro mthe positive terminal of your battery to your alternator.fix this or it will keep working the alternator and draining your battery.

Its probably the alternator. It will need to be tested on the vehicle with the engine running and the light illuminated. Measure the battery voltage with the engine running. It should be at least 13.5 volts. If it is lower have the alternator tested at a shop with a charging system tester.
How did you test battery and charging system?
Your charging system is computer controlled. Check for applicable trouble codes. To check codes yourself, at the least you need an obd2 code reader that will check manufacturer specific codes as well as po codes.
Take wire connector loose from generator . The two wires on the left should show battery voltage, do they? What is the voltage spec? This is with key off and no charger hooked up.
The two wires on the right are to and from the computer, To check those, at least, you need a digital multimeter that has a duty cycle or frequency setting, with engine running, should activity on both wires. You have a battery temp sensor that could cause problems.
?€¢
The IPC determines that the system voltage is less than 11 volts or greater than 16 volts. The IPC receives a class 2 message from the body control module (BCM) indicating the system voltage

Actually, I need to clear things up a little. I had the problem of the battery going dead which led to the replacement of the alternator a little over a year ago. About 6-8 months ago the Charging light would blink an the truck gave a tone every so often. About a month ago it started happening more frequently, which led to the entire elec. system shutting down. The engine would run until the battery was depleted. That's when I had the system tested and replaced the bad battery. It ran fine that day, but the next day it started flashing the light again. I uncovered the alternator wiring harness to check for bad wires and found nothing wrong. It continued to show the light, but I have't lost electrical power since. I have had the engine shut off on me after the light flashed off and on continuously for about 5 minutes. The electrical stayed on, so I pulled the key out and opened my door to shut off elec. I then closed my door and tried to restart the truck. After it turned over a few times it finally started again and I got to my destination. I have driven it once more since then. It only flashed the light with nothing else failing. I can also tell when right before the Charging System light is going to illuminate. All electrical items will show a decrease in power (lights, ect.) and then the light will illuminate. Another thing that's been happening for a while now, when I roll my windows up and the window can't go anymore, it will draw a ton of power from the electrical. Thank you for any help you can give me.
