Accessory Battery Connection; Water Pressure - Evinrude E-TEC 90 H.O. Original Instructions Manual

Product Information
Tighten all connections securely and coat the
installation with Triple-Guard grease.
A WARNING
Keep the battery connections clean,
tight, and insulated to prevent their
shorting or arcing and causing an explo-
sion. If the battery mounting system
does not cover the connections, install
covers. Check often to see that connec-
tions stay clean and tight.
NOTICE
DO NOT use wing nuts on bat-
tery connections even if they came with
the battery. Wing nuts can loosen and
cause errant warning signals or electrical
system damage.
Service
Before servicing the battery or the outboard,
remove both battery cables from the battery,
battery negative (–) cable first. Keep metal
objects from contacting either battery post.
NOTICE
Service electrical components
only while the outboard is NOT running.
Be careful when identifying positive and
negative battery cables and posts.
A WARNING
Battery electrolyte is acidic — handle
with care. If electrolyte contacts any part
of the body, immediately flush with water
and seek medical attention.
Do not use a booster battery and jumper
cables to start the outboard. Gasoline
fumes can cause explosion and fire,
resulting in property damage, personal
injury or death.

ACCESSORY BATTERY
CONNECTION
An optional accessory battery charge kit is
available to allow the charging system to
charge the cranking and accessory batteries
at the same time. See your Dealer to order
and install this kit (P/N 5006253).
IMPORTANT: The accessory battery connec-
tion must only be used to charge a single 12-
volt battery or two 12-volt batteries wired in
parallel. The accessory connection must not
be used to charge either battery in a 24-volt
system.

WATER PRESSURE

An optional water pressure gauge is recom-
mended to monitor cooling system pressures.
Noticing changes in water pressure can help
prevent engine overheating. The water pres-
sure gauge must be connected at the correct
point to ensure the most accurate pressure
readings. Follow the installation instructions
included with the water pressure gauge.
