sult the manufacturer's literature, included in owner's

D. 12-Volt Electrical System Shutdown Procedure
When leaving your boat unattended for an ex tend ed
period of time it is advisable to shutdown the electrical
system to reduce battery drainage and/or possible
electrical draw.
To shutdown:
1. Turn ignition key to the "OFF" position and
remove key.
2. Turn the battery switch to the "OFF" position.
E. Electrical System Maintenance
1. Battery Maintenance
Be sure to keep the batteries charged. Also, keep the
batteries clean, especially the terminals and con-
nection lugs. Be sure the batteries are fas tened
securely while in use.
Check the battery fluid level often, especially when a
charger/converter is being used. Replen i sh a battery
indicating a low charge. Determine the reason for the
dis charge. Lack of battery usage is as detrimental to
battery longevi ty as is overuse. Alternating battery
usage is impor tant. Refer to the battery manufac-
turer's instruc tions 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
15 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.
2. Electrical Wiring Maintenance
Periodically, inspect all wiring for nicks, chafing,
brittleness, improper support, etc. Spraying the
electrical connections with an electrical connection
cleaner will reduce corrosion and improve electri cal
continuity.
DO NOT allow corrosion to build up on con nec-
tions. This can cause equipment to operate
improperly.
The American Boat and Yacht Council (ABYC) has
published a standard for the color coding of boat
wiring. Scarab voluntarily complies with these stan-
dards so a qualified service technician can install new
equipment or troubleshoot the electrical system. The
following table (Figure B31) summarizes the color
code system:
