The voltage regulator Harley regulates the voltage through Harley Davidson’s instrument gauges, the speed meter, and the cluster , as its name implies. The driver can track the bike’s speed and motor life with the aid of the voltage controller’s visual display.
What are the symptoms of a bad voltage regulator on a motorcycle?
- Motorcycle won’t start. This one’s the big, obvious one. ...
- Spluttering as you drive. When voltage is low, it’s hard to keep the motorcycle running.
- Lights light up and dim as you rev. ...
- Battery warning light comes on.
What are the symptoms of a bad voltage regulator?
A bad voltage regulator can even affect your car’s engine. For example, as this car part stops working properly, you might notice your car’s engine sputters or stalls once in a while. It might also have trouble accelerating as you drive .
What happens when you have a bad voltage regulator?
A damaged or failed voltage regulator can rapidly diminish the alternator’s ability to cycle power from the battery . This may cause the vehicle to experience dimming or pulsating external systems, such as headlights and dashboard elements.
How do you test a voltage regulator on a Harley Davidson?
To check the regulator unplug it from the stator. Take a test light and clip it to the negative terminal of the battery and then touch first one pin and then the other on the plug that goes to the regulator. If you get even the slightest amount of light from the test light the regulator is toast.
Can I drive with a bad voltage regulator?
A bad voltage regulator may cause it to simply not work or behave erratically . You’re not likely to be able to start the car at all, but even if you could, it wouldn’t be wise to do so without knowing how fast you’re driving, how much fuel you have left, and other critical info.
How long does a voltage regulator last?
For the most part, the instrument voltage regulator is supposed to last for the life of the car . Like with any other electrical component of a car, eventually this voltage regulator will begin to show signs of damage.
What are the signs of a bad stator?
The most obvious symptoms of a bad motorcycle stator include no spark, weak spark , or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.
Is a voltage regulator the same as a rectifier?
Perhaps the biggest thing to note is that a rectifier converts input AC power into DC electrical power. Regulators are, on the other hand, systems configured to automatically maintain a constant voltage level to protect various apparatus against damage that can be caused by fluctuating voltage.
What causes a voltage regulator to overheat?
Why is the voltage regulator heating up? ... The greater the difference between input and output voltage or the greater the current, the more heat will be dissipated by the regulator . This means linear power regulators are not very efficient at regulating voltage, since so much energy is wasted as heat!
Can you replace a voltage regulator?
This is possible because the modern voltage regulator is a sold-state device. ... When you have tested the charging system of a car fitted with an alternator , and the checks in How to test a car battery point to a fault in the voltage regulator , make sure that you need to replace it.
How much does it cost to replace a voltage regulator?
Between $345 and $386 is the average cost for a voltage regulator replacement. Labor costs are between $155 and $196 and parts are priced at $190.
How many volts should my Harley run at?
Check the voltage of the battery while it is disconnected from the bike using the multimeter. The volts should be no less than 12 volts .
How many volts should a Harley stator put out?
For example a 32-amp stator should put out 18 volts AC (VAC) per each 1000-RPM. At 2000 it should be 36 VAC (18×2). At 3000 RPM it should be 54 VAC (18 X 3).
How many volts should a Harley start?
Harley-Davidson motorcycles use either a 6 volt or a 12 volt battery. Harley-Davidson motorcycles made after the early 1960s are using 12 volt batteries, while older Harleys made before the early 1960s are using a 6 volt battery.
