Electrical components on bikes, including voltage regulators and rectifiers, can prove puzzling. However, those who take the time to understand what regulators and rectifiers do will have the power to figure out future issues on their own. Most modern bikes have these two parts as one unit, but older bikes can often have them as two separate items. These parts have two functions on your bike: The motorcycle's rectifier takes the power as it comes from the alternator and converts it from alternating current (AC) into direct current (DC). Then the regulator regulates voltage as this power is transferred to the battery, keeping it within acceptable limits and converting excess energy to heat, which is then dispersed.
With all of that technical explanation out of the way, you can now understand that the regulator/rectifier on your motorcycle is a vital component, ensuring your battery continues to get power as your bike runs without overloading it. Only shop from the best brands here at J&P Cycles and once you have the right part, make sure to pick up a mount for your new regulator rectifier.
