An alternator resistor is a device used in an automobile’s electrical system that limits the amount of current flowing from the alternator to the battery. The resistor can be either internal or external and is typically connected in series with the output wire from the alternator. Its purpose is to reduce electrical noise, prevent overcharging of the batteries, and limit voltage spikes caused by sudden changes in engine speed.
The resistance value should match what was specified by the vehicle manufacturer for optimal performance. When replacing an alternator it may also be necessary to replace this resistor as well if it has become damaged or worn out due to age or excessive use.
The alternator resistor is a critical component in modern vehicles. It helps regulate the voltage output of the alternator, ensuring that it does not overload and damage other components in the vehicle’s electrical system. The alternator resistor also acts as a safety device to prevent overcharging of the battery and subsequent failure due to excessive current flow.
Without an alternator resistor, your car could suffer from damaged wiring, worn out spark plugs, or even engine stalling due to too much power being sent through its circuits. If you suspect your vehicle might have an issue with its alternator resistor, it’s important to get this checked out by a professional mechanic as soon as possible for proper diagnosis and repair.

What Does an Alternator Resistor Do?
An alternator resistor is an electrical device that works to reduce the voltage of an alternator. It does this by controlling the amount of current being drawn from the alternator, which helps protect other components in a vehicle’s electrical system from potential damage caused by overvoltage.
Alternators work when electricity passes through a set of coils to create magnetism, which then causes electrons to flow and generate power for the car’s battery and other electrical systems.
The problem with this process is that sometimes too much current can be passed through these coils leading to higher than normal voltages in those systems. To prevent this, an alternator resistor is used as it limits how much current can pass through while still allowing enough energy for all systems in the car so they remain operational without any issues or damage occurring.
What Ohm Resistor for Gm Cs 130 Alternator?
Choosing the right ohm resistor for your GM CS 130 alternator can be a daunting task. Depending on the amount of current flowing through your system, you need to select an appropriate resistor that won’t overheat or create too much resistance in your electrical circuit. Generally speaking, most GM CS 130 alternators require a 2 ohm resistor for optimal performance.
This allows enough power to flow through the system without creating any additional strain on the unit itself. When selecting a resistor for this application, it’s important to look at its power rating and ensure that it will not exceed what is recommended by the manufacturer of your alternator.
Additionally, you may want to choose one with higher wattage if you are expecting more output from your vehicle’s electrical system.
Choosing the correct ohm resistor is key to ensuring efficient operation of your GM CS 130 alternator and avoiding unwanted problems down the road!
Are All Ls Alternators the Same?
No, not all LS alternators are the same. They come in a variety of sizes and shapes, with different amperage ratings so they can work on different vehicle types. The most common size is a 130 amp unit, but you can find higher amperage units that go up to 160 amps or even 200 amps for high-performance applications.
Additionally, some LS alternators may have an internal voltage regulator while others will require an external one. Some models include features such as adjustable output voltage, remote sensing capabilities and more which allow for customizing your setup depending on your needs and requirements.
Ultimately, it’s important to make sure you purchase the correct size and type of alternator for your specific application in order to ensure maximum performance from your system.
What is D+ on Alternator?
The alternator is a key component in any vehicle’s electrical system, and it is responsible for the conversion of mechanical energy into electricity. A D+ terminal on an alternator refers to the connection point between the DC voltage regulator and the main output circuit.
This connection point allows for regulation of current flow from the alternator to ensure that all other components connected are receiving consistent power.
The D+ terminal can also be used as a diagnostic tool to test for issues such as weak or bad connections, damaged wires, faulty grounding points, or defective parts in your car’s charging system. In order to keep your vehicle running properly, it is important that you inspect this connection regularly and replace any damaged components if needed.
Doing so will help ensure that your car continues to receive adequate power without causing further damage down the line.
