Hook this into your shore-power line, then hook the Galvan Alert to the power station. If excessive corrosive currents are present and working through your boat’s ground wire, an LED indicator illuminates to warn you to keep an eye on the anticorrosive systems. The device also warns of reverse polarity connections and shows when correct power is present. $150; westmarine.com
