What can damage a voltage regulator?
Here are a few common causes for voltage regulator failure:
- Damaged ground wire.
- Corroded or worn-out battery terminal.
- Loose battery connection.
- Overheating of some electrical component.
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.
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.
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.
How much does it cost to test a voltage regulator?
This meter will be able to read the voltage running through your battery and will indicate whether your regulator is working properly. A multimeter is often much less expensive than other complex diagnostic tools and can cost from anywhere from $14 to over $100. Open the hood of your vehicle.
How do you change the voltage regulator on a Harley Davidson?
This specific video shows you how to change your Harley voltage regulator, also known as the voltage regulator rectifier. We remove the old regulator and the wire off the 30 amp breaker and install a new voltage regulator and wire it correctly. We then insert the plug into the Stator allocation.
