Experienced mechanics share their insights in answering this question :
One of your wires may be shorting out your alternator, check to see if there are corroded wires on your wiring harness. Also, as I’ve seen in the past there may be a problem with wires on your starter. Also, I understand that your alternator is good but is it big enough for your car? You may have an aftermarket component that is drawing power from your alternator.
I hope these are helpful tips. You may want to have certified technician, such as one from Yourmechanic, come out to check your car and diagnose your electrical issues firsthand.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Common reasons for this to happen:
Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine.
Voltage in the system is approximately 450 volts DC.
The most common reasons a Ford Mustang Mach-E won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Ford recalled more than 48,000 Mach-E SUVs on June 10, 2022, NHTSA Campaign Number 22V412000. This was because they discovered that the high voltage battery main contactors could overheat. When and if this happens, it can cause the vehicle to lose drive power. This, in turn, will increase the risk of a crash.
A faulty crankshaft position sensor will be unable to identify the exact piston position, triggering an engine misfire. This causes your car to shut off while driving. A drop in performance, fuel efficiency, rough engine, etc., are some important symptoms of a damaged crankshaft position sensor.
Cars shouldn`t shut off while driving, but when they do, the most common culprits are: A bad crankshaft position sensor. Other sensor issues in the engine. A faulty fuel system.
At home you can charge from a 120 Volt outlet or a 240 Volt source. The extended range battery pack has 99 kilowatt hours of storage. Every Ford Mustang Mach-E vehicle comes with a dual voltage 120 V / 240 V charger.
If the battery is in a good state, the multimeter should show a reading between 12 and 13 volts. Measure the starting voltage of your Mustang: With the tips of the multimeter in the same position, and without breaking contact, we must turn the engine on and check how much the voltage drops when the engine starts.
Why Your Car Battery Keeps Dying. While car batteries slowly die over time, high heat, brutal cold, excessive use of vehicle accessories (after-market equipment), and other mechanical issues can shorten the life of even the toughest battery.
Another possible scenario (especially if you have an old car) is that your car`s ignition switch is worn out. This can cause a car to shut off while driving, but the fact that you noticed a gradual electrical shutdown—rather than everything stopping at once—suggests an alternator or battery issue.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit. Your engine needs air to run properly as well.

2005 Chrysler 300C changed battery and alternator. Car started, ran, and then battery light came on. Shut car off and wouldn’t start.
ANSWER : Hi. There is a couple of things that could be wrong here. The battery or alternator that was just installed could be defective. Theses parts need to be tested for proper operation. There also could be a fuse, fusible link, or wiring for the battery or charging system that is blown or broken causing the battery light to come on.
The codes that you have will cause the car to shut down, run rough, or not start at all. The crankshaft sensor and camshaft sensor should be replaced. I suggest having a certified technician from YourMechanic come diagnose the charging system and check engine codes to help you proceed with correct repairs.
Battery light is on, car didn’t crank, took power post off battery and car shut off does this mean I need a new alternator??
ANSWER : You should never disconnect a cars battery while the engine is running or you may cause a voltage surge that can burn out the computers and modules/components in the car causing more problems. This is a test that was done on cars before they were computer controlled. Your battery light needs to have the battery and charging system checked to see if the alternator needs replaced. You will also want to check the main cable from the alternator to the main fuse power panel to make sure the wiring is not shorted anywhere in between.
My car shuts off while driving and then turns back on multiple times or shuts off after driving and car turns off.
ANSWER : Hi there. Check the alternator and make sure that the wiring it connected tight. Check the battery cables and make sure that they are tight and clean. Look for any loose ground wires to the chassis on the vehicle. If everything checks out to be working correctly, then the PCM may need to be replaced as it may have a battery disconnect condition. If you need further assistance with multiple functions shutting off, then seek out a professional, such as one from Your Mechanic, to help you.
Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.
Purchased a battery last November…Recently my battery light came on. Then now my car lost power and it won’t drive forward?
ANSWER : Hello, thank you for writing in. The warning light is indicating an issue with the charging system in general. This means the alternator may also be having issues keeping the battery charged. This also validates you issues while driving, as the alternator is what supplies the vehicle with power once the car is started. When all of the warning lights illuminate, it is because they all depend on the alternator’s electrical supply, and are not getting it. You can have the alternator tested on the vehicle, or remove it and have it bench tested. For more help with this, contact our service department to schedule an appointment.
Just put a new carburetor, battery, starter relay, alternator, car stalls out while driving and battery dies when restarted
ANSWER : The battery should be load tested. Simply charging the battery or measuring voltage is not adequate. Measure charging output, too. You want to confirm that the ignition system, including for instance the ignition coil and ignition switch, are not intermittently cutting out. Coils can fail as temperature rises (resistance increases with temperature) so if you run the car for a while and all of a sudden it quits, measure the resistance of the coil windings to see if that provides a clue. Apart from that, the ENTIRE primary side ignition circuit has to be checked, using voltage drop testing (and testing of the hall effect sensor in the distributor), to rule the primary side in or out. If you want the required diagnostic steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a stalling diagnostic and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Car died while driving so I replaced the alternator and battery and car won’t attempt to turn over. What else could it be?
ANSWER : The initial failure was likely caused by a sudden fuel system (e.g., failed fuel pump) or electrical (including ignition) faiure. Prior to performing diagnostics be sure you have a fully charged battery that passes a load test. Then, confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. If the starter motor is not functioning, check for power to the starter motor when the key is held in the "start" position. If there a large voltage drop at the starter motor or no power at all, you may have a faulty ignition switch but you do have to check out the entire starter circuit, which includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch and terminations. On the other hand, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced. If you desire that a certified mechanic resolve this, please simply request a no start diagnostic and the responding certified mechanic will get the problem diagnosed and repaired for you. Please let us know if you have further concerns or questions as we are always here to help you.
