ELECTRICAL SYSTEM
6.1
A 12 V D.C. electrical system is used throughout the vessel for
lighting and operation of pumps and various accessories. For any
12 V current to be delivered, the following criteria must be met:
1. Charge in the battery
2. M a st e r sw i t c h i n "Batt. 1" - " B a t t . 2" - or "Both" position
3. Master circuit breaker on the electrical panel - 'ON ' (if vessel
so equipped)
4. Circuit breaker for the individual appliance - (cabin lights,
running lights, etc.) -'ON'
5. Switch on the appliance ( if there is o n e , such as cabin
light) - 'ON •
The battery monitor installed on the electrical panel will give
an indication of the charge status of the battery,or bank of batteries
when optional battery installed, to which the battery selector has
been switched. The battery monitor will show a high reading, between
13.6 and 14V when the engine is on and the alternator is charging.
When the battery is fresh and fully charged, the battery monitor
will read between 12.8 and 13.2V.
The amount of charge going into the batteries is shown on the
ammeter in the engine panel in the cockpit, if so equipped. Generally,
this meter will show a high rate of charge as soon as the engine
starts, and the charge will taper off as the batteries come up to
full charge. The voltage regulator automatically regulates the
amount of charge going into the batteries, and reduces the level to
prevent the batteries "boiling" over as they reach capacity. For
this reason, even though an engine has a 55 amp alternator, charging
the batteries for an hour will NOT put a full 55 amp-hours back into
the battery.
On boats equipped with three or more batteries, the #1 position
on the battery bank select switch indicates the "primary" use or
