It also controls electrical power to the vehicle s different electrical systems.

How to test internal voltage regulator on alternator.

Simply put the regulator restricts the amount of voltage being sent to the battery. Voltage regulators are commonly found in vehicles and other electronic equipment. Tools used in the video volt meter. 01 test voltage across the battery terminals with the engine running.

Alternator failure voltage regulator stator problems slip rings worn out etc but make also sure your battery still can take the charge check the alternator belt. This is enough to destroy the car s battery and electrical system.

A good alternator should maintain battery voltage between 13 9 and 14 8 volts 14 2 is optimum. A voltage regulator controls the alternator voltage output to maintain a preset charging voltage for the battery. You may want to take the alternator to a local auto parts store to get tested. A voltage regulator will limit the maximum amount of voltage from a power source and prevents a device or alternator from shorting and overheating.

The voltage regulator is built into the alternator on all chevys made from the 1980s to at least 2010. In todays video we cover how to diagnose a first gen ford alternator and test the alternator or voltage regulator. There can be many reasons for a lack of charge. Without a regulator the battery would receive upwards of 30 volts of power while charging which would quickly damage or destroy your battery.
