BATTERY VOLTAGE
The level of charge of the battery or batteries may be checked with the
VOLT METER located in the center of the D.C. POWER PANEL. The level of
charge of the battery, alternator output, state of the voltage regulator
and power draw to services can all be checked with the use of the DC
voltmeter. A voltmeter gauge is located on the engine instrument panel.
Your voltmeter will indicate differently, depending when the readings
are taken. Here are a few simple guidelines. Fully charged batteries
that are in a static state should. read between 12.3 - 12.6 volts on the
numerical scale, and just barely be touching the high end of the yellow
band on the colored dial of a gauge. (The term static means that the
battery hasn't been charged or discharged for at least two hours.) If
the pointer is in the yellow or red low band on a gauge, or reads
between 11 - 11.5 volts on a voltmeter, then the battery is about half
discharged and should be charged to insure its usefulness. If the
engine is started, and the needle does not move up, this would indicate
that no charge is being delivered to the battery.
When the battery is being charged, the pointer should be between 12.6 -
13 volts, which is approximately the center of the green band on gauge
types. The pointer may move up to about the 13.7 volt range (the high
end of the green band) toward the end of the charge cycle, at which time
the pointer drops back to the 12.6 -13 volt range, as voltage regulation
controls this function. If the battery voltage reaches 15 volts (which
is the high red band on the gauge) this indicates that the battery is
being overcharge~ and will damage the battery if left unchecked.
When the battery is being discharged (having electrical loads placed
upon it) and no charging current applied, it is normal for the pointer
to indicate between 11.4 - 12.6 volts, or be in the yellow band.
A FINAL WORD - The above guidelines provided are merely to help you to
establish what is normal - the usefulness of the meter will depend on
your own routine observations which will spot trouble when it occurs.
The BATTERY TEST SWITCH adjacent to the meter is used to directly
connect the meter to the individual battery(s). The condition may then
be read directly from the meter. The BATTERY SELECTOR SWITCH must NOT
be in the ALL position and the engine should NOT BE RUNNING or false
readings will result.
The battery(s) should be inspected and serviced at least once a month,
more frequently when under heavy use. The terminals should be free from
corrosion and tight on the battery posts and the electrolyte kept at the
proper level by topping up with distilled water.
CAUTION: Avoid spilling battery electrolyte into the bilge and avoid
getting any salt water in the battery. If this should occur, ventilate
extremely well since poisonous gas will be given off. Avoid contact
with eyes or skin using proper protection at all times.
If battery fluid comes in contact with any surface, wash thoroughly with
clean, fresh water immediately.
