SOURCE: alternator light on

The alternator is not producing any power . If it were the engine would run without the battery. Check the wiring on the alternator. It must ave an exciter wire to make it work.

SOURCE: Charging Light On After Replacing Alternator/Battery1999Windstar

Hi, I can't tell you exactly what is wrong because there is too much involved at this point, what with 2 shops working with it, but I can give you some advise on what else to check. On the alternators and the wiring that supports them a small volt charge is taken off one of the slip rings, where the brushes ride, for the purpose of turning out the light. As I remember, this is a yellow wire that runs back to the dash.

To the alternator, it would be one of the wires that plug into the side of the alternator case.

If you replaced the alternator and you have checked all fushes and wires. you most likly recieved bad alt. I would take it off and have it tested.

2008 Expedition 5.4l codes: P0607, P2004, P2107, U1900, B1676.

P0607 - Control Module Performance Description: Indicates that the powertrain control module (PCM) internal central processing unit (CPU) has encountered an error. The PCM monitors itself and carries out internal checks of its own CPU. If any of these checks returns an incorrect value, the DTC is set. Possible Causes:
  • Module programming error
  • Aftermarket performance products
  • Damaged PCM
Diagnostic Aids: Application Key On Engine Off Key On Engine Running Continuous Memory All Reprogram or update the calibration. Check for other DTCs or drive symptoms for further action. Make sure to check for aftermarket performance products before installing a new PCM. If it is necessary to install a new PCM, refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM) .
P2004 - Intake Manifold Runner Control (IMRC) Stuck Open (Bank 1) Description: This DTC is set when the IMRC is commanded closed, but the IMRC monitor indicates open. This DTC replaces P1518 and P1537. Possible Causes:
  • IMRC monitor signal circuit shorted to PWR GND or SIG RTN
  • Damaged IMRC actuator or solenoid
  • Blocked vacuum hoses
Diagnostic Aids: Monitor the IMRC and IMRCM PIDs. The IMRCM state should change when the IMRC is commanded open or closed. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test HU .
P2107 - Throttle Actuator Control (TAC) Module Processor Description: The electronic throttle control (ETC) area of the powertrain control module (PCM) failed the self-test. The concern could be the result of an incorrect throttle position (TP) command, or TAC motor wires shorted together. Possible Causes:
  • TAC motor wire shorted together
  • TAC motor circuit wires short to PWR
  • Damaged electronic throttle body (ETB)
  • Damaged PCM
Diagnostic Aids: A TAC motor circuit PID reading may indicate a concern, if available. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DV .

HELP! 2005 Dodge Stratus 2.4L SXT Stalls Out with OBD codes P0038 P0032 P0700.

Check fuse 13, which provides the field voltage. Also check the 120 amp fuse link for the charge wire.

Alternator went out, truck died, Towed on hauler. Replaced alternator and now gages go crazy Codes are B1676, C1226, P0460 and P1000 I read if its driven the syst1em will reset itself. Is this true?

If the battery voltage is low it will set codes that are not prudent. It is not a good idea to charge a dead battery with the alternator as it causes the alternator to run at high amperage.Charge the battery, clear codes and retry

What does code no bus meAN

No bus means PCM communication error. Common in Chrysler/dodge/jeep product there could be several reasons your getting this code. It could be low voltage due to battery or alternator failing dirty conections or a crank sensor going bad. Try the most inexspensive thing first which is checking and cleaning connections such as battery post etc then have charging and battery system checked at your local autozone. If all check good dissconect your battery for about 15-30 mins and if that doesn't work have crank sensor checked and replaced. Hope this answer was helpful.

Voltage on both leads to IAT connector

12-13.5 V sounds a bit low. Have you checked the alternator? Is there a difference in the voltage when the motor is running (should be higher when the motor/alternator works)? Have you checked the consumption when the car is parked?

2000 ford expedition I changed plugs pcv egr valve cover gasket I am still getting power loss and hesitation in drive and sometimes it stalls plus I have a b1676 code

There is no B1676 DTC. You probably mean P1676 which refers to incompatible injector data. Probable causes are:
1. Control unit software needs updating
2. Faulty PCM or ECM

Checking these two probable causes may get performance back to normal.

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.
    I'll send wiring diagram tomorrow.

    Voltage light comes on. Alternator and battery checked out ok

    There are 3 control modules involved in this problem. The Powertrain Control Module (PCM), the Body Control Module (BCM), and the Instrument Panel Cluster Module (IPC) The alternator is actually controlled by the PCM. The PCM Relays information back and forth to the BCM and the IPC. The BCM recieves charging system information from the PCM and relays it to the IPC telling it whether or not to turn the voltage light on. Your problem could be caused by a communications fault (In which case one or more of these modules will report a U-code when they are scanned) or you may have a faulty voltage lamp control circuit in the IPC. (In which case, the IPC may or may not be reporting it as a problem.) ONE of these modules SHOULD have a code reporting some kind of problem with the charging system. You need to have all of them scanned.
