If your regulator-rectifier has failed, or is starting to fail, then replacement with a new genuine Honda part will help insure against sudden battery discharge. Or, worse over charging, which in the worse case scenario blow the battery up, spraying acid all over the inside of the battery compartment, leading to sever corrosion if left untreated! Check our online catalogue for your model, to see our full range of genuine Honda replacement parts and consumables.
Note: this part is superseded by 31600MA6000.
