The voltage regulator on a 2004 Dodge Dakota is located within the Powertrain Control Module (PCM) . The PCM is responsible for regulating the voltage output of the alternator. It is not a separate component that can be easily accessed or replaced. If you suspect an issue with the voltage regulator, it is recommended to have the PCM checked by a qualified technician.

Will a bad voltage regulator drain a battery?
Yes. It can allow the battery to be discharged to the point the car won’t start, which is very hard on the battery, and it can allow the alternator to overcharge the battery to the point it’s ruined as well. The voltage regulator is seldom a separate part these days.
Is the voltage regulator located on the alternator?
The voltage regulator is this piece right here you can see it’s held down by several torx bits it’s a chunk of solid state circuitry that controls the amount of voltage generated by the alternator.
Where is the voltage regulator located on a 2002 Dodge Dakota?
the alternator voltage regulator is located in the PCM and is called the EVR or electronic voltage regulator; this is connected in series with the alternator and ground. you can tap into alternators Gen. Fld wire with a multimeter test the EVR output which is pulse width modulated.
What are the symptoms of a faulty voltage regulator?
Battery problems, illuminated warning lights, lighting issues, and other electrical oddities are the top symptoms of a bad voltage regulator. A weak battery or a faulty alternator can cause the voltage regulator to fail.
Can you replace just the voltage regulator?
It is possible to replace only the voltage regulator on some vehicles – usually by disassembling the alternator to gain access – but because the other alternator components can wear out over time also, the alternator is commonly replaced.
Where is the voltage regulator on a 2004 Dodge Durango?
The charging system voltage regulator is built into the PCM(powertrain control module). The PCM is your engine control module and controls the fuel injection, charging system and etc. The PCM is located on the right front inner fender in the engine compartment.
Where is the voltage regulator located?
Regulator is either attached to the alternator. Or inside of it in older cars with carburetors. It could be found on the firewall. Some newer cars don’t have a voltage regulator.
What happens when regulator fails?
If the fuel pressure regulator’s diaphragm or any of the seals fail, fuel leaks can happen. A faulty regulator can result in fuel leakage, which is a potential safety hazard. It can also result in vehicle engine performance issues. Usually, a fuel leak results in a noticeable fuel smell.
Does the voltage regulator control the alternator?
The alternator is a simple magnetic field device. It puts out raw power that must be regulated and controlled, like the engine’s speed. This is the voltage regulator’s job, which converts the AC voltage from the alternator into DC voltage. It also regulates how much energy the alternator makes.
Can an alternator work with a bad voltage regulator?
A bad voltage regulator can lead to the alternator undercharging or overcharging the car’s battery. Undercharging can result in a discharged (dead) battery, whereas overcharging can cause internal battery damage. If neglected the bad regulator can permanently damage the battery.
