The boat manufacturer may replace the fuse and holder with a circuit breaker. Have your
boat manufacturer or dealer show you the location and identify the fuse or circuit breaker
for your reference.
OVERLOAD PROTECTION FOR OTHER CIRCUITS
Other circuits may be protected by circuit breakers or fuses installed by the boat
manufacturer and can vary in appearance and location.
For example, the MerCathode system has a 20‑amp in‑line fuse in the wire that connects
from the positive (+) battery terminal to the positive (+) terminal on the controller. If the fuse
is defective (open), the system will not operate, resulting in a loss of corrosion
protection. Have your dealer show you the location of and service procedures for the
fuse.
Ask your dealer for the location and operation instructions of all overload protection
devices.
Galvanic Isolator and Monitor
These power packages feature anodes as standard equipment to help protect them from
galvanic corrosion under moderate conditions. The MerCathode System and sacrificial
anodes provide corrosion protection under normal usage.
Boats connected to AC shore power require additional protection to prevent destructive
low‑voltage galvanic currents from passing through the shore‑power ground wire. A
Quicksilver Galvanic Isolator or equivalent isolation device is recommended to block the
passage of these currents while providing a path to ground for dangerous fault (shock)
currents.
IMPORTANT: If AC shore power is not isolated from boat ground, the MerCathode System
and anodes may be unable to handle the increased galvanic corrosion potential.
