How long can you drive with battery light?

How long can I drive my car with the battery light on? If your battery light stays on while you drive, you’ll have roughly 30-60 minutes to drive with your battery lights on before your car may start stalling.

Why is my check charging system light on?

What’s happening when the battery/check charging system light comes on? Whenever this light goes on, it means that the vehicle is running solely on battery power. If the problem continues and your charging system fails, the battery won’t be able to recharge and it will soon run down, leaving you with a dead battery.

How do you tell if its your battery or your alternator?

If your engine won’t turn over or takes far longer than usual, it’s time to grab the jumper cables and attempt a jump-start. If your engine starts and stays running but won’t start again later, it’s likely a battery problem. If your vehicle immediately stalls, it’s probably a bad alternator.

How do know if your alternator is bad?

7 Signs of a Failing Alternator

Dim or Overly Bright Lights.
Dead Battery.
Slow or Malfunctioning Accessories.
Trouble Starting or Frequent Stalling.
Growling or Whining Noises.
Smell of Burning Rubber or Wires.

What are the symptoms of a failing alternator?

4 Symptoms of a Faulty Alternator

Car Won’t Start. A dead battery almost always lies behind a car that won’t start.
Engine Stalling. A dead alternator almost always leads to a car that won’t start.
Electrical Issues. A dying alternator can lead to a wide range of other electrical issues.
Unusual Sounds.

How do you check an alternator with a screwdriver?

Unlock the car hood from inside and open the hood to get access to the engine as well as the alternator. The hood either automatically stays secured or you’ll need to secure it with the rod in place. Now place the screwdriver near the alternator pulley bolt. It is usually located in the front of the alternator.

Why is my new alternator not charging my battery?

The most common reason an alternator is not charging the battery is due to worn carbon brushes or a damaged alternator itself. It can also be caused by a blown fuse or bad wirings. If your serpentine belt snapped off, the alternator will, of course not charge then either.

P0625 battery light on Ford Fusion

The alternator in Ford Fusion cars manufactured after 2014 is equipped with an inbuilt voltage regulator. A P0625 code indicates that the charging mechanism is malfunctioning, and the battery light may be illuminated. Starting with the electrical loads switched on (such as the blower, heated seats, defogger, and so on), check for voltage at the battery connections. A voltage measurement of 13.5 volts or above shows that the battery is charging. This car is equipped with power management, which means that the alternator will not charge if it does not need to be charged at the time.

If the alternator isn’t charging

Internal voltage regulation is included into the alternator of Ford Fusion automobiles manufactured after 2014. It is possible that the battery light is illuminated when a P0625 code is received. Starting with the electrical loads switched on (such as the blower, heated seats, defogger, and so on), check voltage at the battery terminals. Charging occurs when the voltage measurement is 13.5 volts or above. It is fitted with power management, so the alternator will not charge if there is no need for it to be charged at all.

If the alternator does charge with the voltage regulator disconnected

Check the brown/red wire in the voltage regulator connector to make sure it is not frayed. You should be able to view the battery voltage. If this is not the case, check fuse55 10A, which is situated in the battery junction box. Rick Muscoplat has a new year’s resolution. Rick Muscoplat posted a blog entry on

Generator Field/F Terminal Circuit Low Voltage Article byStephen DarbyASE Certified Technician

What does that mean?

This is a general diagnostic trouble code (DTC) that may be found in a wide range of OBD-II automobiles (1996-newer). Automobiles from Ford, Hyundai, Mercedes-Benz, Sprinter, Land Rover, Kia, and other manufacturers may fall under this category, but is not restricted to them. Despite the fact that the processes are basic, the specific repair procedures may differ based on the year, make, model, and engine configuration. A recorded code of P0625 indicates that the powertrain control module (PCM) has detected a voltage signal from the generator field coil circuit that is lower than predicted by the PCM.

Probably the most distinctive feature of the field coil is its windings, which are visible via the vent holes on the majority of alternators.
It is the armature that rotates within the field coil, which is activated by the battery voltage.
Whenever the engine is running, the PCM is constantly monitoring the continuity and voltage level of the generator field circuit.
If a problem is discovered when monitoring the generator field circuit, the code P0625 will be saved, and a malfunction indication light (MIL) may be lit to indicate that a problem has been identified.

Depending on the perceived severity of the problem, it may be necessary to perform many failure cycles in order to illuminate the MIL. An example of a typical alternator is as follows:

What is the severity of this DTC?

A stored code P0625 might result in a range of drivability issues, including a no-start and/or a dead battery state, depending on the circumstances. It should be classed as severe in this instance.

What are some of the symptoms of the code?

The following are possible symptoms of a P0625 problem code:

The charging system lamp is illuminated
There are concerns with the engine’s driveability. Unintentional engine shutdown
Delayed start-up of the engine
And other recorded codes

What are some of the common causes of the code?

The following are examples of possible causes for this code:

Fuse or fusible link that has blown or been burned
Open or shorted generator field control circuit Alternator/generator that is not working properly
Faulty PCM
PCM programming problem

What are some P0625 troubleshooting steps?

The diagnosis of code P0625 will need the use of an automotive diagnostic scanner, a battery and alternator tester, a digital volt/ohmmeter (DVOM), and a reputable source of vehicle information. Inquire with your car’s information source to see if there are any technical service bulletins (TSB) that mimic the code saved as well as the vehicle (year, make, model, and engine) and symptoms displayed. If you can locate the right TSB, it may provide useful diagnostic information. Starting with a car diagnostic port connection and extracting all saved codes and freeze frame data, connect the scanner to the vehicle.

Remove any important information from the car after recording it and then clear the codes and test drive the vehicle until the code is reset or the PCM enters ready mode.
It may even be necessary for the condition that led the P0625 to be kept to deteriorate more before a diagnosis can be determined.
Make use of the battery/alternator tester to load-test the battery and ensure that it has received adequate charge before using it.
To determine the minimum and maximum voltage output requirements for the battery and alternator, refer to the manufacturers’ suggested specifications.
Utilize your source of vehicle information to collect connector face views, connector pin-out charts, component locators, wiring diagrams, and diagnostic flow charts that are specific to the code and vehicle in issue, as well as any other information you may want.
If this is not the case, examine the system fuses and relays and replace any broken parts as needed.

It is fairly uncommon for the field coil to be an integral element of the alternator and to be unable to be replaced independently.

2016 Ford Fusion OBD2 Code P0625 Generator Field/F Terminal Circuit Low – MyCarSpecs Denmark

Known as Generator Field/F Terminal Circuit Low, Error Code P0625 indicates that a fault has been discovered in the generator field control circuit, which is frequently caused by too shorted connections or a malfunctioning control area network (CAN). This is a general issue code, which means it applies to any and all vehicles equipped with the OBD-II system, particularly those manufactured between 1996 and the present. The 2016 Ford Fusion is particularly susceptible to this problem, as are other Ford models, as well as Hyundai and Kia vehicles, Land Rover vehicles, and Mercedes-Benz vehicles.

P0625 is an error code that indicates that the PCM (powertrain control module, also known as ECM or engine control module in other 2016 Ford Fusionmodels) has concluded that the voltage signal from the generator field coil circuit is lower than intended.
Its windings, which can be seen through the vent holes of most alternators, make it the Field Coil, which is undoubtedly the most identifiable of the alternators.
A rotating armature is contained within a field coil, which is energized by the battery.
The PCM continuously monitors the voltage level and continuity of the generator field circuit throughout each cycle of the engine’s operation.
It will register a fault code and illuminate the Check Engine light if the PCM detects an issue while monitoring the generator field circuit.

Common Symptom

As previously stated, this code causes the Check Engine light to illuminate, but it will also illuminate the Charging System bulb. This code causes drivability difficulties in the engine, such as unintended engine shut-off and delayed engine cranking, among other things. In addition to these codes, there might be more.

Possible Causes

Some of the most prevalent reasons of this error code are as follows:

Fusible connection that has been burned
Fuse that has blown Generator field control circuit that is open or shorted
PCM that is defective
PCM that has a programming issue

How to Check

As with other error codes, troubleshooting this problem involves the use of a diagnostic scanner, a battery/alternator tester, a DVOM (digital volt/ohmmeter), and a dependable source of 2016 Ford Fusioninformation and guidance. See whether your 2016 Ford Fusioninformation can be found in the TSB (technical service bulletin) that corresponds to the code saved, as well as the 2016 Ford Fusion (year, make, and model), the engine, and the symptoms. If you locate the appropriate TSB, you will be provided with the appropriate diagnostic information.

In the event that the problem is just intermittent, you may want to write down this information.
Generally, if the PCM enters Readiness Mode, it signifies that the code is intermittent and that you must wait for the problem to worsen before you can correctly diagnose and perform the required repairs.
Then, using the battery/alternator tester, load-test the battery to ensure that it has been correctly recharged.
Maintain the minimum and maximum voltage output requirements for the battery and alternator in accordance with the guidelines and standards set forth by the manufacturer of the battery and alternator.
Make use of a 2016 Ford Fusioninformation source to acquire component locations, connection face views, connector pin-out charts, wiring diagrams, and diagnostic flow charts that are connected to the problem code shown on your 2016 Ford Fusion.

If this is the case, inspect the system’s fuses and relays and replace any damaged components. It is reasonable to presume a faulty alternator or generator if voltage is detected at the field coil control terminal of the generator.

How to Fix

The following are examples of frequent repairs for this code, depending on the diagnosis:

Electrical component replacement (blown fuses)
Replacement of the control module ground strap
Disconnection of CAN pins and testing of the pins (this can be a costly and time-consuming procedure, and it should be done last)

This code may result in a variety of drivability difficulties, including no-start and dead battery conditions, among other things. As a result, it has to be handled as quickly as feasible. Furthermore, the field coil is a critical component of the alternator and cannot be changed independently from the rest of the unit.

What Does Code P0625Mean?

Fault code for the OBD II P0625 is a general code that is described as ‘Generator field terminal -circuit low,’ and it is set when the PCM (Powertrain Control Module) detects an unusually low voltage in the generator field coil and its related control circuit, which is caused by a short circuit in the generator field coil (s). NOTE: It should be noted that the term ‘generator’ has become synonymous with the term ‘alternator’ in recent years. The field coil in an alternator, also known as the ‘stator,’ is the most immediately recognized component in nearly every alternator because of the copper wire windings that are almost always visible through the alternator shell.

This part of the alternator is called the stator.
This definition is used in conjunction with code P0625.
When the ignition is turned on, electricity is given to the filed coils from the battery through the ignition switch and the charging system warning light, which are both illuminated.
It is at this moment that the alternator is considered to be self-sustaining, which means that the field coils no longer require any current from the battery to function.

An alternator that is completely functioning maintains the current being generated in a range between 13 and 14 volts; however, it should be noted that this range can be as high as 15 to 16 volts in some applications, which is mostly dependent on the kind of battery utilized in the application.

The PCM (or other control module, such as a specialized alternator control module) will set code P0625 when it senses an unusually low voltage in the field coils, as described above.

Notably, whether a warning light is flashed on the first failure depends on the application, as well as upon the nature/severity of the issue.

Where is the P0625sensor located?

The image above depicts an exploded view of the major components of a typical contemporary alternator, as shown in the diagram. The portion labeled ‘Stator’ is a metal ring that keeps the copper windings in place; the field coils are two sets of copper wire windings that protrude from either side of the stator, which is a metal ring that holds the copper windings.

What are the common causes of code P0625?

Should be noted that code P0625 is frequently associated with other codes, which might include those relating to misfires, low fuel pressure, and transmission troubles to name a few possibilities. In most cases (but not all), these and other codes are not activated until after the vehicle has been driven for a long length of time and the code P0625 has been activated and saved. On the practical side, this means that practically all of the extra codes were generated as a result of the battery being depleted, since the malfunctioning alternator was unable to keep up with the current demanded by the fuel, ignition, and other systems that may have been activated.

Incorrectly functioning alternator component(s), which may include the voltage regulator and/or rectifier
Alternator control module that has failed
In the field coil windings, there is an open or short circuit. Note that, as opposed to creating a low voltage in the field coils, this is more likely to result in the alternator not functioning at all. The alternator’s drive belt is slipping. Battery that is not functioning properly
Affected wire and/or connections practically everywhere in the charging system or in the CAN (Controller Area Network) bus system
Damaged, shorted, disconnected, or corroded wiring and/or connectors
PCM or other control module that has failed or is failing. It is important to note that, in contrast to most other codes, a broken or failing control module is a definite possibility, as many of the alternator’s control circuits are included into the PCM.

2013 F-150 Code P0625 – HELP !

I have a P0625 error number that appears after installing a new alternator. There are no additional issues with the system’s pricing; is there anything else to report? According to the Ford repair manual: DTC P0625 or P0626 are the results of Pinpoint Test D. Typical Business Operations The generator monitor (GENMON) circuit, which is part of the PCM, keeps track of the generator output (generator field terminal circuit). When the PCM is unable to read the GENMON circuit due to an open or short to ground, the generator defaults to a steady voltage of approximately 13.5 volts when the engine speed is greater than approximately 2,000 rpm, and the PCM sends a request to the Instrument Panel Cluster (IPC) to illuminate the charging system warning indicator.

A GENMON duty cycle of 98 percent or above indicates the presence of an open or short to voltage fault, which results in the PCM displaying the DTC P0626 error code.

P0626 is a diagnostic trouble code (Generator Field Terminal Circuit High) This DTC is set by the PCM if the GENMON circuit is open or shorted to the power supply.

The following conditions are expected to be diagnosed with this pinpoint test: Fuse Wiring, terminals, or connectors are all examples of electronic components. Adapter for the radial arm Grounding is required for the engine, generator, and battery. PCM Battery Generator (PCM for short).

Red Battery Light

Okay, I’ve just gone out and taken a look about with a multimeter in my pocket. I was unable to locate the little window you stated anywhere on the battery, and other from a carry handle, there was nothing to elevate in order to verify. It has to be a tight budget ‘pain in the rear end’ one! Anyway, after attaching the multimeter, the car sat overnight with nothing in it and the battery voltage was between 11.9 and 12 volts. When I started on the car, the voltage dropped to 11.86v, and I revved it to 2000rpm before stopping.

This to me indicates that the alternator is in good working order, and the fact that I was able to travel more than 150 miles (while using lights, radio, and warmers) indicates that the car is ‘live’ off of the alternator while driving.

Because the light turns on and stays on when the key is turned to start the automobile, I would guess that it is the battery based on logical reasoning.

1) It was more than likely sitting idle at a dealership for a few months, with the engine being cranked every now and then to check it out.

I was working in zero temperatures when the snow reached the moors and I had to leave the project.

Would you agree with me on this point?

thanks
