Where is the voltage regulator located on a car?
Does anyone know were the voltage regulator is located on the car? Tester July 6, 2016, 4:07am #2 The voltage regulator is located inside the alternator. When the voltage regulator fails the entire alternator is usually replaced. Bing July 6, 2016, 4:07am #3 It should be on the alternator or internal to the alternator.
What are the signs of a bad voltage regulator?
Signs of a bad voltage regulator in a vehicle include dimming or pulsing lights or a dead battery. If you have electrical equipment that won’t turn on, that could also indicate a bad voltage regulator—the regulator could either be letting no power through or letting through too much and damaging the other components.
When do you need to replace a voltage regulator?
If your voltage reading is below 13.8 volts, you have a weak battery and will need to replace it soon. Read the schematics that came with the voltage regulator. In order to test a 3-terminal voltage regulator in electronic equipment, you’ll need to know which pins are the input, output, and ground pins.
What should the voltage reading be on a voltage regulator?
Attach the red wire to the input pin and the black wire to the ground pin. Doing this will give you the input voltage reading. This voltage reading should typically be around 1-2 volts higher than what the regulator is designed to output.
Where can I find a voltage regulator for my car?
There are 14 references cited in this article, which can be found at the bottom of the page. Voltage regulators are commonly found in vehicles and other electronic equipment. A voltage regulator will limit the maximum amount of voltage from a power source and prevents a device or alternator from shorting and overheating.
What should the voltage be on a battery regulator?
The regulator should cap the output of your battery at around 14.5. If the voltage reads over 14.5, it probably means that you have a faulty regulator. If your voltage reading is below 13.8 volts, you have a weak battery and will need to replace it soon. Read the schematics that came with the voltage regulator.

Why does my multimeter not read my voltage regulator?
This voltage reading should typically be around 1-2 volts higher than what the regulator is designed to output. If your multimeter doesn’t read anything, it means that your regulator isn’t properly receiving current from your power supply or that the meter is not connected to the correct pins on the regulator.
