look for a fusible link out. You need to check for output on the alternator that you installed. make sure the batteries are fully charged before that, otherwise its not going to read right. start from the source. also, you can disconnect the batteries from the sys and do a continuity check on the wires in the loom, so you can see if current has a path, or if you have an open circuit. hope this helps

SOURCE: which post is which on generator on a 1975 sportster?

the post should be the same as an original. The wires should be green and tan. Green wire goes to the post towards the front wheel and the tan to the post nearest the engine. Don't forget to "polarize" the generator before starting. procedure is in the service manual. Momentarily short between the battery positive post and the field terminal.

641 Ford Tractor late 50 vintage won't charge the battery. Rebuilt the generator it's putting out the right voltage. new battery. Put in 4 different voltage regulators none will charge the battery.


Charging voltage has to be greater than battery voltage. If so, it is reaching the battery? If so, the battery has to charge unless it is defective.

What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.

I have 2003 Saturn Ion and I have bought a new


test the battery voltage while the engine is running, (you'll have to jump it again)
if you know the battery, voltage regulator and alternator are good, you may have to check all the fuse-able links on the car, all the vehicle grounds, and the fuses and relays.
if you put your battery on charge until it is fully charged and let the car sit over night and it is dead, either the battery is internally shorted or the vehicle is drawing far to much current and each circuit tested to find the short.

Why is my 1972 chevelle voltage regulator make noise when you rev it up


If the battery is no good,then you will hear the alternator
hum all the time, trying to charge it

Check for diode problems & A/C Ripple on the circuit

Check all vehicle grounds (wires)

If the wiring is good & the light comes on, it isn't charging
properly,have you not metered that,voltage,amperage &
ripple

You can go through 3 alternators from the auto part chains, to
find a good one.

Have a 1993 ford e350 jamboree that the alternator is overcharging, put new voltage reg. unit on alternator and it seem to fix the problem, but when i went to use it again the charging light came back on...


If you have an engine computer that controls the alternator, you will have to check the wiring from the alt. to the PCM. Also check any fusible links and grounds are often overlooked.
Do you have dual alternators?

SECTION 414-00: Charging System - General Information 2002 E-Series Workshop Manual
DESCRIPTION AND OPERATION Charging System The charging system is a negative ground system consisting of the following:
  • generator
  • integral/internal voltage regulator
  • charging system warning indicator
  • storage battery
  • necessary wiring and cables
The generator is belt-driven by the engine accessory drive system. Refer to wiring diagrams for schematics and locations of the components and wiring.
The battery is a 12 volt direct current source connected in a negative ground system. The battery case is sealed and includes two vent holes to release gases. The battery has three major functions:
  • engine cranking power source
  • voltage stabilizer for the electrical system
  • temporary power when electrical loads exceed the generator output current
The optional dual generator package (7.3L diesel engine only) consists of an upper/lower dual generator system. The upper generator is a 6G 50/110 generator with a 2.49:1 pulley ratio. The lower generator is a 6G 50/110 generator with a 2.32:1 pulley ratio. Thus the upper and lower generators are not interchangeable.
This system is also monitored and controlled by the powertrain control module (PCM). The PCM monitors both the upper and lower generator I circuits to determine both generators' output and set possible fault codes (diagnostic trouble codes [DTCs]). The PCM only controls the lower generator by turning it on or off by opening or closing the lower generator off only when the glow plugs are commanded on by the PCM to avoid possible damage (excessive voltage) to the glow plugs.
Both generators are independent of one another and only control themselves (through their own internal voltage regulator). If one generator fails, the other generator can maintain system performance under light load conditions. Under a heavy load, the PCM should detect a problem, set a DTC and illuminate the warning indicator.
The PCM controls the charging system warning indicator and will command the light on if the PCM detects a problem on the monitored circuits.

1989 f350 7.3 replaced voltage regulator and alternator same time. still not charging


you should have 12.5 volts with engine off at battery and 14.4v with engine running and charging system working. Is alternator light on? please rate, thx.

There are different versions and 1989 is too old to get on line. here is 1993, so take with caution. Also check the fusible link.

Battery Positive Voltage (B+) Output
The generator (alternator) output is supplied through the Battery Positive Voltage (B+) output connection to the battery and electrical system. I Circuit
The I circuit, or ignition circuit is used to turn on the voltage regulator. This circuit is powered up with the ignition key in the RUN position. This circuit is also used to turn the indicator on if there is a fault in the charging system operation or associated wiring circuits A Circuit
The A circuit, or battery sense circuit, is used to sense the battery voltage. This voltage is used by the regulator to determine the output. This circuit is also used to supply power to the generator (alternator) field coil. This circuit is connected back to the load distribution point and is a protected circuit. S Circuit
The S circuit, or stator circuit, is used to feedback a voltage signal from the generator (alternator) to the regulator. This voltage, typically 1/2 battery voltage, is used by the regulator to turn off the indicator.

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.

    Can I use a 8 volt battery on a 6 volt tractor or will it trip the voltage regulator and blcck the generator?


    YOU CAN USE AN 8 VOLT BATTERY, IT SHOULDN'T HURT ANYTHING. THE ONLY THING IS IT WON'T STAY FULLY CHARGED. THE GENERATOR IS DESIGNED FOR A 6 VOLT BATTERY NOT 8 VOLTS. WHAT I DO IS CHANGE THE SYSTEM TO 12 VOLTS. NOTHING WILL HAVE TO BE DONE TO THE STARTER, IF THE TRACTOR STARTS LIKE IT IS SUPPOSED TO. IT WILL JUST START FASTER. YOU WILL NEED NEW POINTS & CONDENSER & A RESISTOR FOR THE DISTRIBUTOR. ALSO A 12 VOLT BATTERY & A MID 1970'S INTERNALLY REGULATED ALTERNATOR, MOUNTED IN PLACE OF THE GENERATOR. THIS A LITTLE WORK BUT THE TRACTOR WILL START AMAZINGLY FAST. I HAVE DONE THIS SEVERAL TIMES & IT WORKS GREAT. IF THE FUEL GAUGE STILL WORKS YOU WILL NEED A SPECIAL RESISTOR FOR THAT. OF COURSE ANY LIGHTS WILL HAVE TO BE CHANGED TO 12 VOLT GOOD LUCK. DR. VOLT.

    Honda S2000 engine installed in kit car. How do I wire alternator


    Unfortunately the Honda alternator is regulated by the ECU, which allows the ECU to intelligently reduce alternator engine loading to improve fuel consumption. The intelligent system uses an electrical load detector (ELD) located near the battery to control the alternator output voltage. A two wire alternator has an inbuilt regulator that will always generate the required charging voltage. When a battery is fully charged and the electrical loading is low there is no need for generating the charging voltage, in this situation the honda alternator will reduce the output voltage to reduce engine loading, hence improved fuel economy.
