BATTERY
Troubleshooting
Removal
WARNING : Battery BLACK negative ca-
ble must always be disconnected first and
connected last. Never charge or boost battery
while installed in watercraft.
Proceed as follows :
1. Disconnect the BLACK negative cable first.
2. Disconnect the RED positive cable last.
3. Remove the vent line from the battery.
4. Remove the holding straps.
5. Withdraw battery from watercraft being careful
not lean it so that electrolyte flows out of vent
elbow.
CAUTION : Should any electrolyte spill-
age occur, immediately wash off with a
solution of baking soda and water.
WARNING : Electrolyte is poisonous and
dangerous. Avoid contact with eyes, skin
and clothing.
Cleaning
Clean the battery casing, caps, cables and battery
posts using a solution of baking soda and water.
CAUTION : Do not allow cleaning solution
to enter battery.
Remove corrosion from battery cable terminals
and battery posts using a firm wire brush. Rinse
with clear water and dry well.
Inspection
Visually inspect battery casing for cracks or other
possible damage. If casing is damaged, replace
battery and thoroughly clean battery tray and
close area with water and baking soda.
WARNING : Should the battery casing be
damaged, wear a suitable pair of non-ab-
sorbent gloves when removing the battery by
hand.
Inspect battery posts for security of mounting.
Inspect for cracked or damaged battery caps, re-
place defective caps.
WARNING : Battery caps do not have vent
holes. Make sure that vent line is not ob-
structed.
Hydrometer Test
A hydrometer measures the charge of a battery in
terms of specific gravity of the electrolyte. Most
hydrometers give a true reading at 21°C (70°F).
A. Specific gravity 1.260
In order to obtain correct readings, adjust the ini-
tial reading by adding .004 points to the hydrom-
eter readings for each 5.5°C (10°F) above 21°C
(70°F) and by subtracting .004 point for every
5.5°C (10°F) below 21°C (70°F).
SYMPTOM : DISCHARGED OR WEAK BATTERY
CAUSE REMEDY
1. Battery posts and/
or cable terminal
oxidized.
Clean and coat with
dielectric grease.
2. Loose or bad
connections.
Check wiring and
connector cleanliness,
damaged or short circuit.
3. Faulty battery
(sulfated, doesn’t
keep a full charge,
damaged casing,
loose post).
Replace.
4. 15 amp fuse burnt
or faulty rectifier.
First check fuse.
If it is in good condition,
regulator.
5. Faulty battery
charging coil (or
stator)
Replace.
