PM/OV Filter and OV Protection Kit (14v).

This 14 volt kit provides crucial over-voltage protection to our permanent magnet alternator (BC433-H) and others rated at 30 amps or below. Comes with a clear-yellow warning light that will illuminate if the crowbar over-voltage protection module is tripped (or when the alternator switch is left off), and a filter capacitor to reduce radio noise and enhance regulation.
