Honda CSC29 Rectifer Bridge Assembly Replacement

はじめに

Are you having issues with sluggish electrical components in your Honda? An issue with the Diode Trio on your Alternator's Rectifier Bridge will cause voltage to leak from your car battery, hampering its performance. The diodes act like one-way check valves, splitting AC current into a positive and negative branch that redirected to the positive and ground terminals of the car battery.
