SOURCE: 98 ford windstar has battery light on put new

The problem is the voltage regulator is bad. However the regulator is almost as expensive as a rebuilt alternator so unless the alternator as been replaced recently I would suggest to go with the rebuilt alternator.

SOURCE: ford windstar van, 2003

I had a small plastic piece replaced in the transmission and it solved the problem(2007). My car was still under warranty, so it only cost me about $100.00. The actual cost was closer to $900.00 because of the labor involved. I used the Ford Dealer in Schulenburg, Texas. They would know exactly what you are talking about, if you ask them.

SOURCE: 2000 Windstar no charge light

Check all connections to alt. and battery to make sure they are clean and tight, as it sounds like a loose or dirty connection someplace. Possibly something not tightened completely after battery and alt. replaced? (just enough to get the annoying light to go on occasionally)

Our 2007 Ford Freestyle 3.0V6 shows B1318 code, also scanner shows low battery voltage module. Car shuts off.Please help what to do to fix?


Which module ?

B1318 Battery Voltage Low Audio Control Module REFER to Section 414-00 . B1318 Battery Voltage Low DSM REFER to Section 414-00 . B1318 Battery Voltage Low DVD Player REFER to Section 414-00 . B1318 Battery Voltage Low Instrument Cluster REFER to Section 414-00 . B1318 Battery Voltage Low RCM REFER to Section 414-00 . B1318 Battery Voltage Low Satellite Radio Receiver REFER to Section 414-00 . B1318 Battery Voltage Low SJB REFER to Section 414-00 .
According to this charging system isn't working correctly ! This is a computer controlled charging system .
Principles of Operation
The powertrain control module (PCM) controlled charging system determines the optimal voltage setpoint for the charging system and communicates this information to the voltage regulator. This system is unique in that it has 2 unidirectional communication lines between the PCM and the generator/regulator. Both of these communication lines are pulse-width modulated (PWM). The generator communication (GEN COM) line communicates the desired setpoint from the PCM to the voltage regulator. The generator monitor (GEN MON) line communicates the generator load and error conditions to the PCM. The third pin on the voltage regulator, the A circuit pin, is a dedicated battery voltage sense line.
The charging system voltage is controlled by the PCM. The generator charges the battery and at the same time supplies power for all of the electrical loads that are required. The battery is more effectively charged with a higher voltage when the battery is cold and a lower voltage when the battery is warm. The PCM is able to adjust the charging voltage according to the battery temperature by using a signal from the intake air temperature (IAT) sensor. This means the voltage setpoint is calculated by the PCM and communicated to the regulator by a communication link.
The PCM simultaneously controls and monitors the output of the generator. When the current consumption is high or the battery is discharged (the PCM recognizes this and increases the output of the generator to accommodate), the system is also able to increase the idle speed to increase the charge.
To minimize the engine drag when starting the engine, the PCM does not allow the generator to produce any output until the engine has started. The PCM then progressively increases the output of the generator.
The PCM turns the charging system warning indicator off after the engine is started and illuminates it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The charging system warning indicator is also illuminated by the PCM whenever the key is ON with the engine OFF.
This is a System 4 charging system, which uses the GEN MON and GEN COM lines to control and monitor the charging system through the PCM. System 4 charging systems are virtually identical in design and therefore, share the same diagnostics. The circuit numbers and colors may be different, but the functions are the same.

Backup lights are 12 volt constantly, so how do I install my backup camera that only needs 12 volt when put in reverse. 2003 Ford Windstar SEL


All I can do is give you access to the wiring diagrams at this site and you can look up the best place to wire in the camera. http://bbbind.com/free_tsb.html

Code b1318 2001 ford ranger edge 3.0. What would cause this code


my book says b1318 code is "low battery voltage at module" this is a self test the engine control computer (ECC) does to measure the power comming to it that runs it. it means voltage at module has been less than 11 volts , try unhooking battery cable for like an hour , also good time to clean your battery terminals (BOTH OF THEM) reconncet battery OBSERVE polarity Very important (red to+) this should reset fault rescan after driving a few miles if code persists then you;ll have to look farther for a bad /dirty power connection around battery and assoc items

Battery dyes after not running 48 hrs+ ? 2003 Windstar minnewan.


There may be a factory service bulletin (FSB) for your Windstar that can correct the problem. It took three battery changes and replacement of a rear wiring harness to fix my 2000 Windstar. Also, using the rear blower and leaving it on with the vehicle shut down may be the source of the problem

2003 Ford Windstar won't start


Either your battery has failed or the alternator/ regulator/rectifier has. With the engine running, check the DC voltage at the battery terminals it should be above 13 volts but below 15. If it is outside this range then your alternator or regulator has failed. This is the most likely. If it is in this range then you need a new battery. As you have changed the battery it may need changing again if the rectifier has failed. but hope it is the alternator giving no output.

Ford mustang gt 2005 dtc codes


B1318 are related to low battery voltage .
B1202 is fuel sender circuit open.
P0463 is fuel level sensor circuit, (high input.)
If your gauge appears to be working o.k. all I would do for now is double check my voltage at battery with engine off & running, to make sure all is good there, erase codes & start fresh. The cheap way to erase is to remove neg (-) cable form battery for about 5 min., or more & then reconnect. You eill lose your memory on radio stations & have to re-set them though, otherwise have someone hook-up scan tool to erase them. Is vehicle starting & running o.k. at this time?
