I have a pramac p4500 I have 240volts out but I have no voltage to charge the battery
For some reason the battery will not charge the gen is electric start but can't get 14 volts out to charge it I have changed the front pannel/ecu and the regulator but still no luck
if you can carefully put a metal wrench on the rotating pulley of the alternator and felt a magnetism attracting the metal wrench, then your alternator is charging. if there is no magnetism, then the alternator is not charging...
another test is to measure the voltage on the small wires that went in to the alternator that says "F" for field, it should measure battery voltage...that is the voltage from the regulator..that means your regulator is working...but the altrntor is not..
without that battery voltage, then the regulator is he culprit...
Reset the Roomba by removing it from the charger, then holding "spot" and "dock" for about twelve seconds. When you let go, the unit will play an ascending series of notes. Then recharge it overnight. If the run time is still short, give Customer Support a call-- be sure to have the Roomba with you when you do.

Your best bet would be to have a qualified repair shop diagnose the problem. Your vehicle has a smart charging system, computer controlled. Hooking up a factory or some other type of professional scan tool an checking for DTC'S - diagnostic trouble codes would be a good first step. Checking battery - cables and connections using voltage drop testing would be another good thing to do . Cables can be bad an you wouldn't be able to tell just looking at them.

Principles of Operation NOTE: The information contained in this section is for Escape, Mariner only. For Escape Hybrid information, refer to Section 414-03 and Section 414-05 .
This vehicle is equipped with a powertrain control module (PCM)-controlled charging system which 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 PCM uses a calibratable algorithm to estimate battery temperature and to reduce battery damage caused by over and under charging. Using this algorithm, the PCM determines the optimal voltage setpoint for the charging system and communicates this information to the voltage regulator on the GEN COM circuit. While this is occurring, the PCM is also monitoring the GEN MON circuit for charging system information, such as transient electrical loads or errors.
If the PCM senses when the charging system receives a transient electrical load (which may cause poor idle quality, such as an idle roll) the PCM can then adjust the injectors opening time to account for the transient electrical load. In this manner, the PCM can maintain a consistent idle speed.
If the PCM detects a charging system error, it broadcasts a CHARGING SYSTEM STATE STATUS message through the controller area network (CAN) communication link, causing the instrument cluster to illuminate the charging system warning indicator. The charging system warning indicator is illuminated if the PCM fails to see a signal on the GEN MON circuit for a time period greater than 500 ms. This telltale is used to indicate over-voltage conditions detected by the PCM.
The PCM also reduces the mechanical load on the starter by initially commanding a low voltage setpoint (using the GEN COM circuit) in order to improve start times and reduce load on the starter and its related system.
Each time the key is cycled to the ON position, the instrument cluster initiates a bulb check by illuminating the charging system warning indicator. This operation is called prove-out. The PCM then issues a CHARGING SYSTEM STATE STATUS - OK message if the charging system is functioning properly. This message is sent once the engine is running and the charging system is determined to be operating correctly. If the cluster does not receive an OK message, the cluster lights the charging system warning indicator indefinitely. Vehicles equipped with a message center display CHECK CHARGING SYSTEM any time a charging system error is present.
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. System 4 charging systems may use any type of generator, as the generator type usually depends on the engine packaging and/or output requirements versus cost.

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.
connect a pair of jumper cabells to the gen connect the pos to the gen side of the gen and the negative to the feald side and hook them to a hot car batt momentarley do not do wial running . should stop probleam good luck
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.

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.
