Are there any voltage regulators on all cars?
Voltage regulators are not found on all vehicles, however they serve an important function for the ones they are found on.
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.
Can you bypass the voltage regulator on an alternator?
On many alternators (except those with computer voltage regulation), you can bypass the voltage regulator to test whether your voltage regulator or some other component (alternator or charging circuit) is at fault.
Why do you need a voltage regulator in your car?
This article has been viewed 252,334 times. 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.

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.
What should be the output of a voltage regulator?
Typically, if you’re facing the front of the regulator, the left pin should be input, the right pin should be output, and the middle pin is usually the ground pin. You will also need to know how many volts your regulator is supposed to output. Typical voltage regulators for computer equipment will be anywhere from 5-12 volts.
