it is inside the alternater, not stand alone.
A charging system test is done to check the internal voltage regulator. It can be done at any auto parts place.
with a regulator tester kohler sale one that will test most regulators

with a kohler regulator tester
You need the test equipment and a bunch of knowhow.
With engine running, ensure system voltage is in the 13-14 volt range.
Usually the voltage supplied to your battery when the engine is running is about 13.5-14 volts max. If the output is higher or lower than 12 volts, then the regulator could be faulty. hope this helps
To install a new wiring harness for the voltage regulator on a 1990 Mercury Topaz, first, disconnect the battery to ensure safety. Remove the old harness by detaching the connectors from the voltage regulator and any securing clips. Connect the new wiring harness to the voltage regulator, ensuring all connections are secure and properly aligned. Finally, reconnect the battery and test the system to ensure the voltage regulator is functioning correctly.
have the battery checked and test the voltage regulator
You will need to go to a repair shop and have them test the charging system.
Test/replace the voltage regulator. The year, make and model info would help.
Hi there the voltage regulator isnormally located at the back of the alternator which is located at the front side of the engine. there is a simple way to check that the regulator is working and that is to connect a multimeter to the car battery but before connecting it to the battery make sure that the multimeter is set to 20 volts dc then connect the red test lead to the battery positive terminal usually marked with a + mark and the negative test lead to the negative battery terminal then start the engine you should get a reading of 13.8 volts then rev the engine slightly and observe the reading it should increase to between 14 and 15 volts but no more than this if it is much higher then the regulator is probably faulty test 2 with the meter still connected to the battery and engine running switch on all lights ect and the voltage should drop below 13 volts switch all lights ect off and it should return to 13.8 volts this will confirm the voltage regulator is working. hope this helps from kev.
