Can you replace the voltage regulator in an alternator?
Replacing a separate regulator outside the alternator is straighforward, whether it is a modern transistor type or one of the electromagnetic kind fitted to some imported cars. With the battery disconnected take the connections off the regulator. Label the leads to avoid confusing them.
Should I replace my alternator or voltage regulator?
