How To Test Internal Voltage Regulator On Alternator

This is enough to destroy the car s battery and electrical system.

How to test internal voltage regulator on alternator.

There can be many reasons for a lack of charge. If you have electrical equipment that won t turn on that could. 01 test voltage across the battery terminals with the engine running. Tools used in the video volt meter.

In todays video we cover how to diagnose a first gen ford alternator and test the alternator or voltage regulator. 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. Voltage regulators are commonly found in vehicles and other electronic equipment. Simply put the regulator restricts the amount of voltage being sent to the battery.

A voltage regulator will limit the maximum amount of voltage from a power source and prevents a device or alternator from shorting and overheating. It also controls electrical power to the vehicle s different electrical systems. A voltage regulator controls the alternator voltage output to maintain a preset charging voltage for the battery. Even worst case with all.

Without a regulator the battery would receive upwards of 30 volts of power while charging which would quickly damage or destroy your battery. Without a voltage regulator an alternator may put out up to 250 volts. You may want to take the alternator to a local auto parts store to get tested. A good alternator should maintain battery voltage between 13 9 and 14 8 volts 14 2 is optimum.
