(Performed by a qualified marine technician)
Verify the integrity of the boat’s entire AC shore power grounding
system, including the connection to the DC system negative.
Verify that any galvanic isolators (if installed on your boat) meet
current American Boat & Yacht Council (ABYC) standards and are
fully functional.
Inspect shore power cords, adapters and boat receptacles for any
signs of deterioration, including cord wear, loose connections, signs
of sparking or overheating and bent or pitted blades. If there are any
such signs, examine, correct, and test the equipment or replace it.
Operate the boat’s electrical system at full load (everything on) and
check for AC system leakage or voltage between the boat’s under-
water fittings (bonded system, if equipped) and the shore side AC
system ground.
General Electrical System Information
Electrical panel and shore power inlet wire connections may possi-
bly loosen over time. Chaparral recommends having your dealer
check these connections at least annually, or if you are having any
electrical system problem.
Due to potential electrical shock hazard,
do not attempt this service procedure yourself.
Your dealer is
trained to properly diagnose and correct electrical problems safely.
Galvanic Isolator
A galvanic isolator is installed in your boat and electrically con-
nected between the boat’s AC panel ground and the dockside AC
ground wire. The galvanic isolator is designed to permit AC ground
currents to pass safely between the boat and the dockside, but to
block the small DC currents that flow in seawater between boats in
a marina because different metals on the boat are in the water.
When the shore power cord is connected to boat and breaker, the
green light on the panel should be on
