A Harley Davidson voltage regulator is a device that controls the flow of electricity through the motorcycle’s electrical system. A good regulator will keep the battery voltage at 13 volts, as the motorcycle’s parts need 13 volts to function properly. If the voltage drops below this point, the regulator will cut off the power supply to the battery.
Changing your Harley’s voltage regulator is a fairly simple process. You can even do it at home if you have the right tools. You can find these tools at a local hardware store or motorbike supply store. While it may sound difficult, it’s an easy job that can save you from spending a small fortune on a Harley repair shop. In addition, the job should only take you about 15 minutes to complete.
A bad voltage regulator can cause your motorcycle to overheat, stop working its tail lamps, or even cause the battery to release flammable gasses. It can also lead to cluster errors, which can signal the engine is due for an overhaul. Even if you aren’t having problems while riding, you should still pay attention to your voltage regulator and its symptoms.
To remove the regulator, unscrew the two 3/8-inch bolts on the top and bottom of the motorcycle. A socket wrench will help remove the bolts. Make sure to keep the ties you removed in a secure place. You can now see the wiring. If you are uncertain about where the wires go, you can use the service manual to find the location.
Your Harley’s voltage regulator can be a source of a lot of trouble. The main problem with the standard regulator is that it is not efficient. The regulator’s silicon-controlled rectifier is prone to overheating. The resulting heat can damage the regulator. If you want a more efficient regulator, you can upgrade to a MOSFET regulator. This type of regulator runs much cooler and uses simpler circuitry. This means it will last longer.
If your Harley’s voltage regulator is malfunctioning, your bike may not have enough power to operate its gauges and cluster. This could cause your speedometer to flicker or stop working completely. It could also damage your motorcycle’s headlamps, side lamps, and tail lights. So, it’s essential to check your Harley’s voltage regulator.
To test your Harley’s voltage regulator, turn all the electrical accessories on and keep the bike running at its normal RPM. Look for 13 volts on your meter. If you see anything less than 13 volts, it may be a sign that you need to change the regulator. Luckily, the problem is fairly simple to diagnose and repair.
