A Quicksilver Galvanic Isolator kit includes an audio and visual monitor to alert you to faults
that occur. The monitor is a microprocessor controlled, solid state device that will test the
integrity of the Quicksilver Galvanic Isolator and the safety grounding lead. This device will
also supply impressed current to the drive to aid in corrosion protection.
!
WARNING
Improperly conducted AC shore power is an electric shock hazard that can result in
damage and injury. The AC grounding conductor green wire must be connected between
the boats electrical system and the shore power connection in order to provide a path for
fault current and to assist the MerCathode in preventing galvanic corrosion on drive
components. Install a galvanic isolator or similar isolation device in the AC shore power
system in the vessel. Consult a qualified marine electrician for more information.
IMPORTANT: If the Galvanic Isolator alarm sounds and the monitor will not respond to the
reset button, AC fault current may be present and the shore power safety grounding
conductor circuit to shore may be an open circuit. Disconnect shore power immediately.
Refer to
Troubleshooting—Galvanic Isolator
for an explanation of the conditions or
faults that may be displayed by the monitor.
