As a veteran motorcyclist or fan of Harley Davison motorbike, you’re not unfamiliar with the Harley voltage regulator symptoms or simply signs of a failed or bad instrument cluster voltage regulator.
Harley Davidson Voltage Regulator Symptoms: When your engine is running on a faulty Harley voltage regulator, the following symptoms are what you should look out for: Gauges flicker, Instrument cluster fails to power & Clusters that display inaccurate or erratic readings.
Even if you’re a newbie in the motorcycle industry, in one way or another, you may have heard, in some way as separate terms, what a voltage regulator is and what the symptoms of a bad voltage regulator would mean.
If not, as you read this post, you’ll find out there are common issues a motorcycle develops over time. But you need to have a little knowledge about some of them in order to apply some DIY mechanisms when there is no professional at hand to help out.
Essentially, in this post, you’ll come to know what signs to look out for when your Harley voltage regulator gets faulty, how to diagnose Harley voltage regulator symptoms, and the proper fix to apply at any point in time.
What is Harley Voltage Regulator?
Regarded in general terms as the instrument cluster voltage regulator, the Harley voltage regulator is an electronic element of a vehicle, be it cars, motorcycles, motorbikes, or trucks.
As the name suggests, the Harley voltage regulator controls the amount of volt that goes into Harley Davidson motorcycle’s instrument gauges, the speedometer, and the cluster.
It is with the help of the visual display of the voltage regulator that the rider is able to follow up with the bike’s speed and engine vitals.
However, once the Harley voltage regulator is faulty or goes bad, as a rider, you’ll not be able to access important information on the state of your bike’s engine and its running conditions.
Harley Voltage Regulator Symptoms
Hence, when your engine is running on a faulty Harley voltage regulator, the following symptoms are what you should look out for. Also, apply the fix as soon as they are detected.
1. Gauges flicker
One of the first symptoms you discover when your Harley voltage is going bad is that your bike’s gauges show dim or flickering signs. The voltage regulator is responsible for supplying power to the gauges, and once it has a fault, the gauges start to shine dimly, and the indicators flicker at intervals.
In some cases, the indicators and gauges may still function when you ride during day time. However, you notice these signs especially when you ride the bike at night, as you’ll not be able to read the clusters.
2. Instrument cluster fails to power
Another symptom of a faulty Harley voltage regulator is that the cluster is unable to power. In other words, when there is a bad Harley voltage regulator, the instrument cluster becomes inoperable.
What that implies is that the power being distributed to the cluster will automatically be disabled, therefore, rendering the cluster powerless and useless.
In some cases, you may find some Harley motorcycles that will start and ride on. But as you progress in your trip, you won’t receive any information from the instrument cluster in the event of any problem. You can be sure it’s a great risk riding a motorcycle without an active or efficient speedometer.
3. Clusters display inaccurate or erratic readings
A faulty Harley voltage regulator shows erratic or inaccurate readings. That can be dangerous and risky, you know. The gauge indicates inaccurate readings, and this should immediately tell you that your voltage regulator is bad.
Usually, when this happens, what you see is that the numbers displayed change rapidly. Alternatively, the needles may cut on and off in an erratic manner. The implication of that is that you’re unable to read the cluster to know if your engine’s service life is due or not.
It can be very disappointing and frustrating, too, when you have to ride a motorcycle with a faulty voltage regulator.
On the other hand, it is also advisable to check for all of these Harley voltage regulator symptoms as you ride your motorcycle. Do not take anything for granted. Regular servicing of vehicles and engines is also important.
It is not enough to purchase or ride these machines; there is also the need to take prompt and proper care of them. The good news is that Harley voltage regulator symptoms are not too difficult to detect early for a careful rider.
Unlike other brands, all motorcycles and bikes made by Harley Davidson have voltage regulators. There is a need for a proper diagnosis to be carried out in order to know whether your voltage regulator needs a replacement or if you simply have to fix the electrical issues on your bike.
