B. Electrical Wiring Maintenance
Periodically, inspect all wiring for nicks, chaffing,
brittleness, improper support, etc. Examine the shore
power cord closely for insulation cracks and corrosion
in the electrical devices. Spraying the receptacles and
electrical connections with an electrical connection
cleaner will reduce corrosion and improve electrical
continuity.
DO NOT allow corrosion to build up on connec-
tions. Shorts or ground faults can result.
The entire 120 (220) volt circuitry, especially the shore
power cord, should be seasonally tested for proper
continuity by an experienced marine electrician. This
will help detect any short, open wire, or ground fault.
Also, check the polarity indicator system for proper
operation.
0 (0) volt AC electrical power can be danger-
ous. DO NOT attempt to service a system unless
you are familiar with, and experienced in, perform-
ing such service.
H - 11 STRAY CURRENT CORROSION
A. General
Electrically induced underwater corrosion occasionally
affects boats and their related components. This is
referred to as “Stray Current Corrosion” and appears
as surface pitting or deterioration. Stray current
corrosion is the decomposition of chemical com-
pounds by electric current.
Stray current corrosion can be caused by surrounding
boats; an improperly wired battery/charger installation
or other boats that are in close proximity which have
electrical power leakages. Stern drive units are
especially vulnerable to stray current corrosion.
Periodically inspect the engine components to deter-
mine if corrosion damage exists. If stray current
corrosion damage is found, determine and correct the
cause of the stray current to prevent further damage.

connection lugs. Be sure the batteries are fastened
securely while in use.
Check the battery fluid level often, especially when a
charger/converter is being used. Replenish a battery
indicating a low charge. Determine the reason for the
discharge. Lack of battery usage is as detrimental to
battery longevity as is overuse. Alternating battery
usage is important. Refer to the battery manufactur-
er’s instructions included with your battery.
Batteries produce hydrogen and oxygen gases
when being charged. These explosive gases
escape through the vent/fill caps and may form
an explosive atmosphere around the battery
if the ventilation is poor. This gas may remain
around the battery for several hours after
charging. Sparks or flames can ignite the gas
and cause an explosion.
Fire or Explosion Hazard!
Only qualified personnel should install batteries
and perform electrical system maintenance.
Do not expose batteries to open flame or
sparks. Do not smoke near batteries.
Poison!
Sulfuric acid in batteries can cause severe
burns. Avoid contact with skin, eyes, or
clothing. Wear goggles, rubber gloves and
protective apron when working with batteries.
In case of skin contact, flush with water at least
minutes. If swallowed, drink large quantities
of water or milk. Follow with Milk of Magnesia,
beaten egg or vegetable oil. Get medical
attention immediately.
Disconnect the battery before working on
electrical or ignition system to prevent electrical
shock and accidental ignition.
