PERIODIC CHECKS AND MAINTENANCE
Page9-2
The following tests should be performed in the intervals
specified:
9-3.1.1 Quarterly (Every 3 Months)
•
Check the level of the water (electrolyte) within the Lead-Acid
batteries. The plates must be covered. If not, add a small
amount of distilled water.
• Check the voltage of the battery. The battery must have a
chance to “rest” (no charging and no load for a couple of
hours) prior to testing. The following table represents a fully
charged battery:
• Check the battery terminals for signs of corrosion, acid build-
up or loose connections.
9-3.1.2 Semi-Annually (Every 6 Months)
• Check the specific gravity of your Lead-Acid battery(s) with a
Hydrometer. The reading for a fully charged lead acid battery
is 1.260 to 1.280.
9-3.1.3 Annually (Every 12 Months)
The tests performed on quarterly and semi-annual basis,
give a relatively good indication of the batteries’ health.
However, the only way to accurately determine the actual
health of your battery is to perform a Battery Load Test.
• There are two types of Battery Load Tests performed in
the field, Performance and Service. In order to determine
the actual health of your battery a Performance Load Test
is recommended. The Service Load Test determines how
well your battery performs in the boat and doesn’t take
into account the battery’s original rating, which could
result in misleading results. The Performance Load Test
places an accurate load on the battery and compares the
results to the battery manufacture’s specification. The bat-
tery should be replaced if the results are 80% or less than
the manufacture specifications.
9-3.2 Power Cables, Distribution Panels, etc.
• Check all of the connections from the battery to the DC Distri-
bution Panel to the APS for loose or corroded connections.
• Measure the voltage at the battery and at the Processor while
the Clutch or Throttle Servo is driving. There should be no
CAUTION: In many newer batteries, the vent cap is permanently attached, preventing
access to the electrolyte for water level and specific gravity tests. Attempting to
pry off these caps could result in premature battery failure.
