It is no secret that every detail installed in the car performs a specific task. And in the event of a breakdown, other elements may fail, which in turn will lead to high repair costs.

With all this, you need to look not only at the big details, but at the small elements too. The METZGER brand Alternator Regulator is a small part that performs important tasks, namely, it is responsible for controlling the voltage in the generator itself.

The alternator regulator allows you to keep the voltage at approximately the same level. It is thanks to this that damage to the generator can be avoided. And this can happen due to exposure to high temperatures and a constant change in the rotor speed. Without a generator regulator relay, the generator itself will not function normally.

The alternator regulator replacement

It is very important to change the charging relay in time, until the generator begins to break down. It is very important to choose this part, depending on the make and model of the car. This is because the alternator regulator can be of different sizes and shapes. That is why, for replacement, you should choose exactly the same version of the element.
