GREY LADY OPERATING MANUAL
NW Explorations
In the event of a low engine-starting battery, the operator can combine (parallel)
the batteries in the engine room with a rotary switch. This will
connect the
starting and house batteries together!
This way, we can be virtually positive that
our engines will start.
And a third battery (#3, in the engine compartment near the Kohler Genset) is
used exclusively for starting the generator. What redundancy!
Magnum DC Battery Monitor
You can monitor batteries with the Magnum meter on stairway to the galley near
the AC/DC Electrical panels.
The LED’s on this monitor provides the type of charging for the batteries. Bulk
charging when the batteries are in a low state, Absorb charging when they are
reaching a fully charged state and Float charging when the charger is maintaining
a full state of charge.
Do not discharge the batteries below (50%)!
At 50% discharged (250 amp-hours), it could take four hours of shore power or
generator time, or twelve hours of engine operation to recharge them!
The Electrical Panels
The nerve center of the electrical system are the circuit breaker panels by the helm. The panels have two “sections”, AC
& DC.
