Is there a problem with my alternator and battery?
Check the two fusible links in picture they should have battery voltage both sides. The problem may be the PCM but lets run some tests first. Check out the diagrams (Below). Please let us know what you find.
How does an alternator and battery work together?
Anything less than that and your car isn’t even able to start. Both of these car parts control your electrical system. However, your alternator charges your battery while your battery supplies power to your car. The failures of a battery are sudden, while failures of a failing alternator are slow.
How long can a battery last without an alternator?
A good alternator and can last well over a decade, sometimes as long as 15 to 20 years. However, if an alternator does fail on you then you’ll know it fairly quickly as your electrical systems will fail soon afterwards. The charge in your battery does not last long without the alternator there to keep it running properly.
Can a generator be replaced with an alternator?
It appears your system has an alternator which means it is a PCM controller voltage regulator. Generators are the ones with internal voltage regulators and are replaced with the generator. Take a look at the attachments but Navigators with this issue usually have a failed regulator in the PCM. Let me know if you have questions.
What happens if you have a new alternator and the battery is not charging?
The alternator in your car is an integral part of your vehicle’s electrical system. If you have a new alternator and the battery is still not charging, then you definitely have some kind of a problem with your battery that you’ll need to address immediately.
What should I do if my alternator keeps dying?
The alternator is essentially a generator and it keeps your battery charged while supplying additional electrical power for the other systems in the vehicle. If you have a new alternator and your battery keeps dying on you, then there’s definitely a problem that you’re going to need to look into.
How do I know if it’s the battery or the alternator?
Both of these car parts control your electrical system. However, your alternator charges your battery while your battery supplies power to your car. The failures of a battery are sudden, while failures of a failing alternator are slow. Always check your battery first, it can generally tell you which of these two is the culprit.
How long does it take to install an alternator?
If you need to have it installed by the mechanic, then the price might be a bit higher. Depending on where your alternator is located within the compartment, the installation might only take an hour. But if the alternator is difficult to access, it might require removal of other parts and it could take many hours.
What should the resistance be for an alternator?
If all this checks out then I suspect you have a wiring issue. I would perform either a voltage drop or resistance measurement of each of the wires from the PCM to the alternator. Also, through the fusible link from the battery to the alternator. You should have less then a half ohm of resistance.
What happens to power steering after an alternator is replaced?
Usually when brakes pads are replaced and the rotors surfaced, it may make the brakes feel stiff for a while until they wear in, but it shouldn’t impact the power steering at all. The only thing I could think of… Engine sludge?
